Continuing her comeback in style, Jasmine Camacho-Quinn stormed to a 100m hurdles win in 12.32 (1.7m/s) to move to equal seventh on the world all-time list at the Tom Jones Memorial Invitational in Gainesville, Florida, on Saturday (17).
Prior to her season opener one week before, Camacho-Quinn's last outdoor hurdles race had been in 2019 and the Rio 2016 Olympian had started questioning whether her future lay in competing over the barriers.
But her perseverance is paying off and in&nbsp;Gainesville&nbsp;the two-time NCAA champion took 0.08 off her own Puerto Rican record, which had been set in 2018, to make a statement in Olympic year.
Behind her, British sisters Tiffany Porter and Cindy Sember both clocked 12.62, with Brittany Anderson finishing fourth in&nbsp;12.91.

Victories by Dina Asher-Smith and Ameer Webb in the 150m dash were among the key highlights of the Great North CityGames street athletics competition in Newcastle on Saturday (9).
In the women's race, Asher-Smith and Bianca Williams, both members of the silver medal-winning 4x100m relay team from IAAF World Championships London 2017 last month, were head to head over the rarely-raced distance.
Asher-Smith continued her remarkable recovery from a broken foot to win in 16.70 from Williams who clocked 17.00 while Dutchwoman Naomi Sedney was third in 17.40.
Nethaneel Mitchell-Blake, the anchor in the 4x100m men&rsquo;s relay team who won the gold at the World Championships, was denied victory in the men&rsquo;s 150m with the 23-year-old finishing second to Webb of the US who clocked 15.24. Mitchell-Blake finished in 15.26 ahead of Harry Aikines-Aryeetey who clocked 15.38.
There was a rare occurrence in the women&rsquo;s long jump after the top three all recorded the same distance of 6.46m.
Lorraine Ugen took the win on countback with her second best jump of 6.43m superior to that of Latvian Kseninja Balta and Jazmin Sawyers who finished second and third respectively.
"I&rsquo;ve never seen that before, with everyone jumping the same distance," Ugen said. "I kind of like these because they&rsquo;re quite fun, you just get to bring the crowd in and have a fun competition.
&ldquo;I wasn&rsquo;t expecting everyone to jump the same distance! I think it makes it a bit more exciting when it&rsquo;s like 'ooh what&rsquo;s going to happen'.&rdquo;
Desiree Henry got the afternoon off to a fine start with victory in the women&rsquo;s 100m, finishing 0.04 ahead of 4x100m relay teammate Asha Philip, Henry clocking 11.61 for the win. South Africa&rsquo;s Carina Horn was third with 11.78.
Henry said: &ldquo;This 2017 season has absolutely been amazing for me. Just to come away with a win on my last race of the season.&rdquo;
In the first mile of the day, Jordan Williamsz won in 4:05.88, the Australian ahead of Brit Elliot Giles in 4:06.17 and Marcin Lewandowski in 4:06.67.
"It&rsquo;s my first time here," Williamsz said. "I wasn&rsquo;t too sure what to expect - I thought it was more built around the half marathon but that was awesome, such a good atmosphere the whole way around, there&rsquo;s nothing like it, it was nothing like I&rsquo;ve ever run. It certainly blew the expectations I had out of the window.&rdquo;
With Aries Merritt pulling out of the men&rsquo;s 110m hurdles in midweek, the path was cleared for Czech Petr Svoboda to win in 13.62, with American Jarret Eaton second in 13.69 and Koen Smet third in 13.80.
Perri Shakes-Drayton earned a surprise victory in the women&rsquo;s 500m, clocking 1:06.69 ahead of Anyika Onuora in 1:06.70 with Lisanne De Witte third with 1:07.19.
"This wasn&rsquo;t in my plan in terms of being here, because usually after my championships I&rsquo;m done," Shakes-Drayton said. "I&rsquo;ve never done Gateshead before, it&rsquo;s my first time. Today to get the win, I&rsquo;m in a good place.&rdquo;
Nijel Amos won the men&rsquo;s 500m in 59.26 from Guy Learmouth in 1:00.73 and Dwayne Cowan third in 1:01.01.
Melissa Courtney held off the threat of Kenya&rsquo;s Winny Chebet to win the women&rsquo;s mile in 4:33.83, with Chebet second in 4:34.42 and Rosie Clarke third in 4:34.42.
In the men&rsquo;s pole vault, Urho Kujanpaa took victory with 5.45m, the Finn finishing ahead of France&rsquo;s Stanley Joseph and Finland&rsquo;s Tomas Wecksten with 5.30m apiece.

Victories by Dina Asher-Smith and Ameer Webb in the 150m dash were among the key highlights of the Great North CityGames street athletics competition in Newcastle on Saturday (9).

Webb and Asher-Smith take 150m victories in Newcastle

There&rsquo;s plenty of tradition associated with Oslo&rsquo;s ExxonMobil Bislett Games, not the least of which is the strawberry party hosted annually on the eve of the meeting by the mayor of the Norwegian capital in the city&rsquo;s historic city hall.
This year's event ahead of the seventh stop of the 2016 IAAF Diamond League series brought together visiting dignitaries from the athletics world, members of the media and several of the meeting's biggest stars. More specifically, a get-together of several of its fastest.
Dafne Schippers and Elaine Thompson, who&rsquo;ll face off in the 200m at Bislett Stadium on Thursday (9), and Kim Collins, Andre De Grasse and Ameer Webb, three of the favourites in the men&rsquo;s 100m, spoke with members of the media to discuss their preparations and expectations for not only tomorrow night&rsquo;s races, but also where those contests fit into their longer term plans in this all important Olympic year.
<h3>Schippers v Thompson, 2016 round 2</h3>
First up were Schippers and Thompson, who electrified the sprint world last season after their unforgettable 200m showdown at the IAAF World Championships, won by the Dutchwoman in 21.63, a scant 0.03 ahead of the Jamaican. At just 23, the pair emerged as the third and fifth fastest women of all time, giving rise to a rivalry that has the potential to last a very long time. Both said that their outing in Oslo is the next step in improving on those performances in Beijing &ndash; eventually.
&ldquo;I hope to set my best time this season and have a nice race," said Schippers, who this season has already clocked 22.02 over the half lap and 10.83 in the 100m, just outside her 10.81 career best. "I think a fast race is possible. We'll see tomorrow. We'll have some fun."
Thompson, who won the 100m in Rome on 2 June in 10.87 and finished just behind Schippers over 200m in Eugene where she clocked 22.16, has a similar race plan.&nbsp;
&ldquo;I'd like to have a season's best before going in to the (Jamaican Olympic) trials,&rdquo; where she&rsquo;ll have to finish in the top three to punch her ticket to Rio. &ldquo;That&rsquo;s most important.&rdquo;
For both, Oslo's 200m contest will be their last race on the circuit prior to their next big competitions, for Schippers the European Championships in Amsterdam and for Thompson the Jamaican Championships/Olympic Trials in Kingston.
<h3>Collins, De Grasse and Webb chasing season's bests</h3>
Sentiments were similar among the men, the first time that Collins, the 2003 world champion, Andre De Grasse, the world bronze medallist, and Webb, this season&rsquo;s fifth fastest man at 9.94, will meet in the same race.
&ldquo;I just want to improve on my season's best,&rdquo; said De Grasse, who clocked 9.99 in early April and 10.05 in Eugene, both wind-assisted.
&ldquo;I'm hoping for a sub-10 performance tomorrow. I know these guys are going to be able to push me. So I have some work to do.&rdquo;
He&rsquo;s arriving on the heels of Sunday&rsquo;s 20.16 victory over 200m in Birmingham, a performance he said bodes well for Thursday.&nbsp;
&ldquo;I've had a little up and down (early in the season), a few hiccups, but I'm back, and I feel like I can produce a fast time tomorrow.&rdquo;
Collins meanwhile is the fastest of the trio this year at 9.93, an unlikely career best at age 40.
&ldquo;I know these young fellas are coming to get me,&rdquo; said Collins, who won his last outing, the non-Diamond Race 100m in Birmingham, in 10.11. &ldquo;And I'm doing everything I can to make sure they don't catch me.&rdquo;
For his part, Webb was diplomatic.
"Kim Collins is one of my favorite athletes so I'm just looking forward to being in a race with that guy. If I could beat him, that will be one of the greatest things ever.&rdquo;
With career bests of 9.94 and 19.85 already to his credit in 2016, Webb brings the momentum of a breakout season to his first Oslo appearance, one he said he is eagerly looking forward to.
&ldquo;All my times this year have been big time blessings," he said. "I just put in a lot of hard work. Everything's paying off and everything's lining up well for my (Olympic) trials.&rdquo;
<h3>&nbsp;Lavillenie and Barber targetting world lead</h3>
Likewise, Renaud Lavillenie and Shawn Barber, respectively the Olympic and world champions in the pole vault, made no promises or predictions, although admitted that an assault on Sam Kendricks&rsquo; 5.92m world lead might be in the cards.&nbsp;
&ldquo;I've heard some great things about the meet," said Barber, on the eve of his first appearance at the Bislett Games. "So I'm really looking forward to jumping against all these guys tomorrow night."
Barber has topped 5.91m outdoors this season, Lavillenie 5.83m. Both want to go higher tomorrow.
&ldquo;I think we're both looking at the world lead right now and we feel that we have the potential to jump that very soon,&rdquo; Barber said. &ldquo;I want to jump that very soon.&rdquo;
Lavillenie echoed his young rival&rsquo;s appraisal, but insisted that victory was his first priority.
&ldquo;The goal is to win and to keep the lead in the Diamond Race," he said. "Jumping 5.80m would be a good thing but I wouldn't be one hundred percent satisfied with that. I'd like to jump 5.90m, maybe more.&rdquo;

There’s plenty of tradition associated with Oslo’s ExxonMobil Bislett Games, not the least of which is the strawberry party hosted annually on the eve of the meeting by the mayor of the Norwegian capital in the city’s historic city hall.

Oslo press conference highlights – IAAF Diamond League

&ldquo;See you in Birmingham&rdquo; was a common phrase overheard at the closing dinner of the IAAF Diamond League meeting in Rome on Thursday night, and several disciplines being contested at both events, most flights from Rome to England on Friday and Saturday carried world-class athletes ready to contest in their second Diamond League in three days.
No less than 61 current global medallists are set to compete on Sunday (5) but, undoubtedly, one of the most anticipated events will be the women&rsquo;s 100m hurdles.
Only last Saturday Kendra Harrison ran 12.24, the second fastest time in history, in Eugene. She&rsquo;ll be joined in Birmingham by 2013 world champion Brianna Rollins, who Harrison succeeded as US record holder, and who has already a clocked a 12.53 this season as well as 2015 Diamond Race winner Dawn Harper Nelson.
Lining up against the American contingent will be London 2012 Olympic Games champion Sally Pearson while Great Britain&rsquo;s reigning European champion Tiffany Porter will be keen to prove a point in front of her home crowd.
A whole bunch of notable talent in the women&rsquo;s 800m made their way over from Rome.
Lynsey Sharp, who finished third in a SB 1:59.03, is looking to benefit from the home support, but the likes of Burundi&rsquo;s Francine Niyonsaba and USA&rsquo;s Ajee Wilson, the 2016 world indoor gold and silver medallists respectively, will certainly have a say in the distribution of Diamond Race points.
In the women&rsquo;s 100m, English Gardner wants to bounce back from her narrow defeat to Elaine Thompson on Thursday, having clocked an impressive 10.81 in Eugene.
Gardner&rsquo;s main challenger in Birmingham will be reigning 200m world champion Dafne Schippers, who has a season&rsquo;s best of 10.83 from the opening iAAF Diamond League meeting Doha a month ago, but 2015 world long jump champion Tianna Bartoletta and British record holder Dina Asher-Smith are not to be discounted.
<h3>Webb aims for fourth straight 200m win</h3>
The men&rsquo;s 200m begs the question whether Ameer Webb can continue his dominant form on the Diamond League circuit.
The American won the Doha meet in 19.85 and only this week in Rome performed an impressive double, winning the 200m in 20.04 before coming second in 9.94 in the 100m within the space of 80 minutes.
Adding flavour to the line-up will be 2015 Diamond Race winner Alonso Edward and the joint 2015 world championships 100m bronze medallists Trayvon Bromell and Andre De Grasse.
Asbel Kiprop will be the man to beat in the 1500m, but Morocco&rsquo;s Abdelaati Iguider, who gave Kiprop a slight scare in last weekend&rsquo;s Bowerman Mile in Eugene, could be a threat to the Kenyan.
Meanwhile, Jairus Birech will be looking for a little bit of redemption in the men&rsquo;s 3000m steeplechase.
The Kenyan, who won the 2015 Diamond Race fell at a barrier during the final lap in Rome and made the victory an easy one for compatriot Conseslus Kipruto, although the latter is unbeaten this year in three outings over the barriers and has run three successive world-leading times.
The men&rsquo;s 400m might turn into a battle between Grenada and Botswana with world leader Kirani James and Rome runner-up Bralon Taplin representing the Caribbean nation while Isaac Makwala and 19-year-old Thebe Babloki will lead the African challenge.
Lst year&rsquo;s 10,000m world champion Vivian Cheruiyot could have the edge in the women&rsquo;s 5000m, with both Mercy Cherono and Janet Kisa having Thursday&rsquo;s race in Rome still in their legs.
Cherono, however, clocked a personal best of 14:33.95 in the Italian capital and could have Almaz Ayana&rsquo;s almost world record-breaking performance from there as a motivating force.
Eilidh Doyle opened her season with a world-leading 400m hurdles win 54.53 in Doha, but was disappointed with her third place in Rome so the Briton, who finished fourth in Birmingham last year, but will most certainly be aiming for a win this year.
The last time anyone beat Caterine Ibarguen in a triple jump competition was in the 2012 Olympic final and the two-time world champion will be looking to extend her undefeated run to 35 competitions on Sunday.
The Colombian set a world-leading mark of 15.04m in Doha and has since added victories in both the Rabat and Rome to her win, and Diamond Race points, tallies.
<h3>Rutherford back on home soil</h3>
The men&rsquo;s long jump in Birmingham promises also big leaps.
Reigning world and Olympic champion Greg Rutherford, fresh from his 8.31m victory in Rome, will be looking to continue his winning streak on home soil.
One of the main contenders to spoil the party could be Marquise Goodwin. The American currently holds the world lead with 8.45m, but finished second behind Rutherford in Rome with 8.19m.
In the men&rsquo;s discus we can expect Poles Piotr Malachowski and Robert Urbanek to continue their battle for the Diamond Race lead. Urbanek got the better of Malachowski in Rome, with the latter, the 2015 world champion, finishing down in sixth, his lowest place in a competition for almost three years.
If there is one thing the men&rsquo;s high jump in Rome has taught us that it is turning into one of the most unpredictable events of the season.
World indoor champion Gianmarco Tamberi and bronze medallist Robbie Grabarz finished third and second respectively in Rome, with Grabarz getting the edge over Tamberi despite roaring home support. Both are set to renew their friendly rivalry on Sunday.
Meanwhile, Ekaterina Stefanidi leads the Diamond Race in the women&rsquo;s pole vault and has jumped 4.75m outdoor bests at the last two Diamond League outings.
In other women&rsquo;s field events, 2014 IAAF World Athlete of the Year, Valerie Adams is feeling confident following her consistent shot put series and win on Thursday, while Rome javelin winner Sunette Viljoen will face a strong opposition including Germany&rsquo;s 2015 world champion Katharina Molitor.
Two non-Diamond Race disciplines with huge interest will be the men&rsquo;s 3000m where Mo Farah is looking to continue where he left off after running a world-leading time in the 10,000m in Eugene, while Kenya&rsquo;s world and Olympic 800m champion David Rudisha is moving down in distance to contest the 600m.

“See you in Birmingham” was a common phrase overheard at the closing dinner of the IAAF Diamond League meeting in Rome on Thursday night, and several disciplines being contested at both events, most flights from Rome to England on Friday and Saturday carried world-class athletes ready to contest in their second Diamond League in three days.

Rome rematches to feature prominently in Birmingham – IAAF Diamond League

Some of the sport&rsquo;s most exciting new sprint talents will take on four former winners of the Prefontaine Classic 100m at the IAAF Diamond League meeting in Eugene on 28 May.
USA&rsquo;s Ameer Webb has already established himself as one to watch in 2016. A three-time winner of the NCAA 200m title &ndash; twice indoors and once outdoors &ndash; the 25-year-old has twice lowered his 200m PB this season, first with 19.91 at the Mt SAC Relays and then with 19.85 to win at the IAAF Diamond League meeting in Doha.
Last month he set a wind-legal 100m PB of 10.03 and followed it one week later with a marginally wind-assisted 9.90 at the Mt SAC Relays.
Canada&rsquo;s world bronze medallist Andre De Grasse won the 100m and 200m double at the NCAA Championships at Hayward Field last year with wind-aided times of 9.75 and 19.58. He went on to win double gold at the Pan-American Games, then set a PB of 9.92 to earn bronze at the IAAF World Championships Beijing 2015.
These two rising stars will take on four men who have previously won the 100m at the Prefontaine Classic and who, collectively, have won five of the six Diamond Race titles.
World silver medallist Justin Gatlin has won five times at the Prefontaine Classic &ndash; four in the 100m, including a wind-aided 9.76 in 2014, and once at 200m with a meeting record of 19.68.
Jamaica&rsquo;s Asafa Powell has more sub-10-second clockings than anyone else in history. Winner of the 100m at the Prefontaine Classic in 2006, Powell recently took the silver medal at the IAAF World Indoor Championships Portland 2016.
Tyson Gay holds the North American record at 9.69. He also owns the fastest times ever seen at Hayward Field: a wind-aided 9.68 and a wind-legal 9.77. The 33-year-old won the 100m in Eugene last year.
Mike Rodgers won the 100m at the Prefontaine Classic in 2009, setting a PB of 9.94. He then bettered that time at the 2011 edition with 9.85 to finish second.
Su Bingtian finished third at last year&rsquo;s Prefontaine Classic, becoming the first Chinese man to cover the distance within 10 seconds. It was a time he equalled in August in the semifinals at the World Championships in Beijing before going on to take the silver medal in the 4x100m. Earlier this year he set an Asian indoor 60m record of 6.50 at the World Indoor Championships.
Qatar&rsquo;s Femi Ogunode is the current world leader at 9.91, equalling the Asian record he set last year. He won the 100m and 200m double at last year&rsquo;s Asian Championships and ended his 2015 season with an Asian 200m record of 19.97 to win at the IAAF Diamond League final in Brussels.

New talent takes on the old guard over 100m in Eugene – IAAF Diamond League

Tia Brooks twice improved on her personal best to win the shot put at the IAAF Diamond League meeting in Doha with 19.48m and become the first winner of a Diamond Race discipline in 2016 after she managed an upset victory on Friday (6).
Brooks got her first personal best when she reached 19.45m in the second round and extended that by three centimetres with her following effort.
Hungary&rsquo;s world indoor silver medallist Anita Marton applied a little pressure on Brooks when she sent her implement out to 19.22m in the penultimate round but could not improve further with her last effort.
Surprisingly, USA&rsquo;s world indoor champion Michelle Carter failed to get beyond 18 metres with her first three efforts, having a best of 17.83m and placing fifth after three rounds. Under the new IAAF Diamond League regulation which sees only the top four horizontal jumpers and throwers get three more attempts, she failed to make the cut.
Another US woman to win in the field in Doha was the rapidly improving pole vaulter Sandi Morris, who equalled the IAAF Diamond League record when she went clear with her first attempt at 4.83m.
Both Switzerland&rsquo;s Nicole Buchler and Greece&rsquo;s Ekaterina Stefanidi were still in the competition at that stage but neither could negotiate that height.
Morris, the world indoor silver medallist, then had the bar raised all the way up to 4.93m but brought the bar down three times.
Buchler, now 32, took second after clearing a national record of 4.78m on her first attempt.
<h3>Last-gasp win for Malachowski</h3>
On a traditionally still and humid evening in Doha, there wasn&rsquo;t much help from the elements for the discus throwers but world champion Piotr Malachowski still produced a world-leading 68.03m with his last throw to overtake Belgium&rsquo;s Philip Milanov, who finished one place behind the Pole in Beijing.
Milanov had improved his national record by 36 centimetres to 67.26m in the fifth round but Malachowski, lying in second at that point with 65.81m, wasn&rsquo;t to be denied his third straight win in Doha. The world silver medallist had no response and could only foul his final throw.
Eilidh Doyle, perhaps better known still under her maiden name of Child, was the strongest over the final 250 metres of the women&rsquo;s 400m hurdles and showed some crisp clearances over the barriers to win in 54.53 in her first race of the year.
Doyle was just 0.31 away from her personal best and 0.25 away from the meeting record of Romania&rsquo;s Ionela Tirlea-Manolache, the longest standing meeting record in Doha which has stood since 1999.
USA's LaShawn Merrit powered his way to a confident 400m win in 44.41.
Briefly, with a strong penultimate 50 metres off the final bend, Trinidad and Tobago&rsquo;s world junior champion Machel Cedenio looked like he was going to catch the 2008 Olympic champion but the latter weakened more rapidly than Merritt over the final metres and came home second in 44.68.
Ameer Web won the 200m with an impressive piece of sprinting off the bend to win in a personal best and meeting record of 19.85, taking 0.06 off the former mark and 0.17 off the latter.
<h3>Kipruto solo run</h3>
Conseslus Kipruto hit the front in the 3000m steeplechase with less than a kilometre to go, after the last pacemaker had stepped to one side &ndash; with the 1000m mark being passed in 2:39.40 and 2000m and 5:20:00 to keep the runners on course for an eight-minute finish &ndash; and quickly established a 30-metre lead owing to no one being willing to chase him despite the pace dropping slightly.
Kipruto then as good as held his lead all the way to the line. Easing up over the final few metres, he won in a world-leading 8:05.13 with 2015 Diamond Race winner and fellow Kenyan Jairus Birech taking second in 8:08.28.
Erik Kynard&rsquo;s second-attempt clearance at 2.33m was enough to win what was otherwise a slightly lacklustre high jump contest. An ostensibly classy field generally under-performed, apart from the Olympic silver medallist and China&rsquo;s world silver medallist Zhang Guowei, who went over 2.31m but could go no higher and finished second.
Among the men who would have been expected to go higher, world champion Derek Drouin finished down in fifth with 2.29m while local hero Mutaz Essa Barshim looked well below his best and only negotiated 2.26m to finish eighth.
In the middle-distance events, there was a confident and comfortable win for South Africa&rsquo;s Caster Semenya in the 800m, hitting the front with 50 metres to go before winning in a world-leading 1:58.26.
Kenya&rsquo;s Asbel Kiprop looked equally dominant in the 1500m, holding a 20-metre lead at the bell and being enough in command to wave to the crowd with 50 metres to go and start to ease down before taking all 10 Diamond Race points in 3:32:15.
In a repetition of the gold and silver medal placings at the IAAF World Championships Beijing 2015, Kiprop&rsquo;s compatriot Elijah Manangoi took second place in 3:33:67.
In the women&rsquo;s javelin, South Africa&rsquo;s Sunette Viljoen proved to be almost two metres better than the rest of the field and won with her opening effort of 65.14m, going on to have three more throws better than anyone else.

Brooks upsets the favourites in Doha – IAAF Diamond League

World-leading performances by Johnathan Cabral in the 110m hurdles and Jenna Prandini in the 100m were among the chief highlights at the 58th Mt SAC Relays on Saturday (16).
Canadian Cabral, a semi-finalist at last year's World Championships, won his specialty in 13.35 to knock 0.02 from his career best. Mikel Thomas of Trinidad and Tobago was second in 13.40.
Prandini, last year's NCAA champion in the 100m and long jump, clocked 10.95 in her impressive season's debut, finishing just ahead of Hannah Cunliffe who clocked 10.99 to take more than half a second off her PB. It was Prandini's second career sub-11 performance, just shy of her 10.92 PB from last year.
Ameer Webb of the US was also off to a fast start. The 25-year-old former NCAA 200m champion produced a solid victory in the 100m, handily defeating world 100m bronze medallist Andre De Grasse clocking a wind-assisted 9.90 (2.4m/s) to the Canadian's 10.04.
He then came back to dominate the 200m with a wind-legal 19.91 (1.0m/s), the first sub-20 in his career. BeeJay Lee of the US was a distant second in 20.23.
Vashti Cunningham won her professional debut, topping 1.93m in her first competition since winning the world indoor title in Portland last month. The 18-year-old Cunningham reportedly had one close attempt at 1.98m.
&ldquo;I haven&rsquo;t jumped outdoors for a while, so I&rsquo;m happy to be back,&rdquo; Cunningham told the Las Vegas Review-Journal. &ldquo;My goal was 6-6 (1.98m). I skipped 6-5 (1.95m) because I was feeling really good, but I needed more to reach 6-6 today. I just couldn&rsquo;t get it. I just wasn&rsquo;t running fast enough.&rdquo;
Meanwhile, Rodney Brown produced the best performance on the infield, winning the discus with a 66.00m heave. His effort added nearly a metre to the 22-year-old's personal best of 65.04m set last year.
Combined events star Ashton Eaton had a busy and productive Sunday afternoon, first winning the long jump with a wind-assisted 8.09m (2.2m/s) leap ahead of Japan's Shontaro Shiroyama, who reached 7.95m. He took to the track about an hour later and clocked 13.48 in the 110m hurdles, finishing fourth behind Cabral's world lead.
Elsewhere, Briton Cindy Ofili, European sprint hurdles champion Tiffany Porter's younger sister, won the 100m hurdles in 12.66 (2.0m/s), well ahead of Janay DeLoach, who clocked 12.90.
Duane Solomon beat a solid field in the 800m, clocking 1:45.47.
And in the men's triple jump, Alberto Alvarez took the victory with a Mexican record of 16.99m.
The highlight on Friday's busy high school, junior, collegiate and open programme was Saudi Arabian Abdullah Abkar Mohammed's 10.04 victory in the 100m, a national record and Asian junior record. The 19-year-old then doubled back to win an open section of the 200m in 20.29, albeit with an assisting wind of 2.7m/s.
Renovation and an over-haul of the meeting's long-time home, Hilmer Lodge Stadium in Walnut, California, moved the three-day meeting to nearby Cerritos College in Norwalk, which will also host the competition in 2017.

World leads for Cabral and Prandini at Mt SAC Relays

US collegiate records by Tia Brooks in the women’s Shot and Arkansas in the men’s 4x400m relay highlighted the NCAA Indoor Championships at the Randal Tyson Center in Fayetteville on Friday and Saturday (March 8-9), while Lawi Lalang broke the meeting records in the mile and 3000m within the space of two hours.Brooks threw 19.22m in the women’s Shot to crush her PB of 19.00m set at last year’s NCAA Indoor Championships. She broke by seven centimetres the collegiate and meeting record set by Laura Gerraughty in 2004, and in doing so moved up to fifth on the US indoor all-time list. All five of the Oklahoma student’s valid throws would have been enough to win.In the 4x400m Relay, the final event of the weekend, the Arkansas quartet of Marek Niit, Neil Braddy, Caleb Cross and Akheem Gauntlett clocked a world-leading 3:03.50. They turned back Florida by 0.21 and shaved a hundredth of a second off the collegiate record of 3:03.51 by a 2005 Florida team that included two-time World 400m Hurdles champion Kerron Clement. The triumph also put the finishing touches on Arkansas’ 74-59 victory over Florida for its 20th national indoor title and 41st overall.The Oregon women defeated Kansas, 56-44, for their fourth indoor title in a row led by American junior 100m record-holder English Gardner, who placed second to Aurieyall Scott of Central Florida in the 60m, 7.13 to 7.15m, and ran the opening leg of Oregon’s victorious 4x400m relay that ran 3:30.22.Lalang’s record-breaking doubleThe Kenyan-born Lalang was a one-man show, winning the mile in 3:54.74 and the 3000m in 7:45.94 with just one hour and 45 minutes between events. Lalang turned the mile into a solo effort with a hard-charging Ryan Hill of North Carolina taking the runner-up spot in 3:55.25. Both Lalang and Hill were under the 1995 meeting record of 3:55.33 set by Canadian Kevin Sullivan.In the 3000m, Lalang pulled away to win over Kemoy Campbell of Arkansas, 7:45.94 to 7:46.59. Lalang’s time broke the meeting record of 7:46.03 set in 1998 by Adam Goucher. Campbell’s time is an outright Jamaican record, smashing the 7:55.78 outdoor best set by Mark Elliot in 1989.NCAA cross country champion Kennedy Kithuka of Texas Tech, who just missed Lalang’s collegiate record by 0.27 in the 5000m, finished ninth in the 3000m.The last runner to accomplish the mile and 3000m double was Bernard Lagat in 1999. Lagat, coincidentally, is a volunteer assistant coach at Arizona and training partner of Lalang. Abbey D’Agostino of Dartmouth completed a 3000m and 5000m double on the women’s side with times of 9:01.08 and 15:28.11, while US Steeplechase champion Emma Coburn of Colorado won the women’s mile in 4:29.91.In the 60m Hurdles, Eddie Lovett of Florida won the men’s final with a meeting record 7.50. World-leader Brianna Rollins of Clemson won the women’s race in 7.79, just 0.01 off the 7.78 PB she set earlier in the year. Rollins now holds the top three times in the world in 2013.Olympic medallist Drouin and Barrett prevail in High JumpThe men’s High Jump featured Olympic silver medallist Eric Kynard of Kansas State and bronze medallist Derek Drouin of Indiana. Drouin won his third national indoor title in a row with a Canadian record 2.35m. The mark was the second-best collegiate mark in history, just two centimetres off the record. Drouin had first-attempt clearances at his first seven heights, including his winning effort, before having two narrow misses at a collegiate record of 2.38m.The unheralded Marcus Jackson of Mississippi State raised his PB by six centimetres to finish second on count-back ahead of Kynard, both jumping 2.29m.In the women’s High Jump, Barrett won with a season’s best of 1.95m to become the first three-time NCAA indoor winner in the event. In all, Barrett has won the last five national collegiate titles indoors and out.American junior record-holder Andrew Irwin of Arkansas won the Pole Vault at 5.70m and Natalia Bartnovskaya of Kansas was the women’s winner at 4.45m on count-back over Jade Riebold of Eastern Illinois and Martina Schultze of Virginia Tech. In the horizontal jumps, Marquis Dendy of Florida won the Long Jump with a PB of 8.28m to extend his US-leading mark of 8.25m set last month. Bryce Lamb of Texas Tech won the Triple Jump with 16.96m. Andrea Geubelle of Kansas won the women’s Long Jump with 6.55m on count-back over Christabel Nettey, then won the Triple Jump the following day with 14.18m. World lead for Webb in the 200mAmeer Webb of Texas A&amp;M won the 200m in a world-leading 20.37 to successfully defend his title and join an illustrious group of two-time winners in the event that includes Walter Dix (2006 and 2007), Leo Bookman (2003 and 2004), Shawn Crawford (1998 and 2000), Obadele Thompson (1996 and 1997), Chris Nelloms (1993 and 1994) and Michael Johnson (1989 and 1990). US leader D’Angelo Cherry of Mississippi State won the 60m in 6.54 after false starts in the prelims that claimed Dentarius Locke and Marvin Bracy of Florida State. Errol Nolan of Houston won the 400m over Mike Berry of Oregon, 45.75 to 45.83, in two separate timed finals.Kimberlyn Duncan of LSU beat Scott of Central Florida to win the women’s 200m, 22.58 to 22.70, to become the first three-time men’s or women’s indoor winner in the event. Duncan, however, finished seventh in the 60m to Scott.Shaunae Miller, the 2010 World junior champion and 2011 World youth champion, won the women’s 400m with an outright PB of 50.88. Her time is a world indoor age-18 best, but just missed the World junior indoor record (50.82) set by Sanya Richards-Ross in 2004. Regina George of Arkansas was second in 51.05 and World junior champion Ashley Spencer was third in 51.27.Elijah Greer won the men’s 800m in 1:47.13 to become Oregon’s first champion in the event. Jamaican Natoya Goule of LSU won the women’s race in 2:02.00.Clarke wins fourth consecutive men’s Shot titleJordan Clarke of Arizona State defended his title in the men’s Shot with an effort of 20.50m. It was the fourth consecutive national title for Clarke, who won the 2011 outdoor title and swept the indoor and outdoor titles in 2012. In the Weight Throws, Andrew Ziegler of Virginia Tech was the men’s winner at 22.46m, while Felisha Johnson of Indiana State, who won in 2011, was the women’s winner at 23.52m.Kevin Lazas of Arkansas and Erica Bougard of Mississippi State were the winners of the combined events. Lazas won the Heptathlon by just 10 points over Japheth Cato of Wisconsin with a score of 6175 for the smallest margin of victory since the event was introduced in 2004. Lazas, who had personal bests in four of seven events, posted marks of 6.90 in the 60m, 7.55m in the Long Jump, 15.00m in the Shot, 1.99m in the High Jump, 8.27 in the 60m Hurdles, 5.40m in the Pole Vault and 2:49:00 in the 1000m.Lazas had a 50-point lead over Cato entering the 1000m in the final event but had to endure several tense moments while the scores were calculated after Cato ran 2:45.26 to cut the final margin to 10 points.Bougard won the Pentathlon with 4399 points with marks of 8.34 in the 60m Hurdles, 1.75m in the High Jump, 11.00m in the Shot, 6.11m in the Long Jump and 2:10.80 in the 800m.Kirby Lee for the IAAF
