<p>World leaders Christian Coleman and Ryan Crouser reasserted their stature with dominant victories on Friday (27) at the USA Championships at Des Moines, Iowa.</p>
<p>Unheralded sprinter Teahna Daniels scored an upset in the women&rsquo;s 100m. Sha&rsquo;Carri Richardson, who set a world U20 record of 10.75 at last month&rsquo;s NCAA Championships, finished last and did not make the team for the IAAF World Athletics Championships Doha 2019.</p>
<p>The 100m national title was the first for Coleman, 23, the world indoor champion and world indoor record-holder. He was second in the 100m in 2017 behind Justin Gatlin, the eventual world champion. Gatlin qualified for the final but, with a bye to the World Championships, pulled out.</p>
<p>Coleman won in 9.99 into a -1.0m/s headwind after a 9.96 semifinal (-0.1m/s). Michael Rodgers was second and Christopher Belcher third, both in 10.12.</p>
<p>&ldquo;It&rsquo;s just amazing. A long time coming,&rdquo; said Coleman, whose 9.81 in the Prefontaine Classic at Stanford is the fastest time in the world this year.</p>

Ryan Crouser spins to the US title in Des Moines</div>
<p>&nbsp;</p>
<p>Crouser, the Olympic champion, climbed from third to first in the shot put with a fifth-round distance of 22.62m. It was his seventh meet of 22 metres this season and gave him his third USA title.</p>
<p>Joe Kovacs was second at 22.31m and Darrell Hill third at 22.11m to complete the trio going to Doha.</p>
<p>&ldquo;This one was special or me,&rdquo; Crouser said. &ldquo;I had a couple of rough weeks of training.&rdquo;</p>
<h3>Daniels springs surprise in women's 100m</h3>
<p>Daniels won in 11.20 against a -1.7m/s wind. She was fourth at the NCAA Championships but has posted creditable marks all season, featuring times of 10.99, 11.00 and 11.03w (in winning the under-23 NACAC title).</p>
<p>Olympic 4x100m gold medallist English Gardner was second in 11.25. Morolake Akinosun, one year removed from achilles surgery, was third in 11.28.</p>

<p>World champion Tori Bowie, with a bye to the World Championships, did not enter the 100m.</p>
<h3>Scott successfully defends triple jump crown</h3>
<p>Donald Scott repeated as triple jump champion with a wind-aided triple jump of 17.74m in the first round. Will Claye was second with 17.70m and was credited with a stadium record with a wind-legal 17.68m (1.8m/s). Omar Craddock was third with 17.55m.</p>
<p>Christian Taylor, with a bye to Doha, jogged down the runway and intentionally fouled. USA rules require him to compete at the National Championships to be eligible for the team.</p>
<p>&ldquo;I know that it was going to take a toll, and I thought it&rsquo;s better that I stay healthy and really hit it hard on the back end of the season,&rdquo; Taylor said.</p>
<p>Conor McCullough won his first title in the hammer, setting a facility record with a PB of 78.14m to move to eighth on the US all-time list. His distance was the longest by a US thrower since 2012. The 28-year-old was the 2010 world U20 champion and is the son of Conor McCullough, who represented Ireland in the hammer at the 1984 and 1988 Olympics.</p>
<p>Devon Williams scored 8295 points to win the decathlon. He had second-day victories in the 110m hurdles (13.78) and discus (49.47m).</p>
<h3>Felix advances to 400m final</h3>
<p>Allyson Felix, eight months after childbirth, was third in her 400m semifinal in 51.45 to make Saturday&rsquo;s final. The top time was 50.20 by defending champion Shakima Wimbley.</p>
<p>&ldquo;I wish I had more races. But I'm just trying to put myself in a position to give myself a shot,&rdquo; said Felix, 33, who has nine medals from the Olympics and 16 from World Championships.</p>
<p>World leader Michael Norman was fastest in the men's 400m semis clocking 44.04, just ahead of Fred Kerley&rsquo;s 44.09.</p>
<p>Among others advancing to finals were Olympic champion Matthew Centrowitz in the 1500m, bronze medalist Clayton Murphy (1:45.24) in the men&rsquo;s 800m, Ajee Wilson in the women&rsquo;s 800m, Rai Benjamin in the 400m hurdles, world record-holder Kendra Harrison in the 100m hurdles and world champion Emma Coburn in the steeplechase.</p>
