Sprinting to the lead from the gun as is her modus operandi, Olympic silver medalist and former world record holder Dalilah Muhammad was dominant in the women's 400m hurdles, winning in a world-leading 53.88. Gianna Woodruff of Panama took second in 54.88, and Anna Cockrell was third in 55.09. All eyes were on Iowan Erik Sowinski as he tried for his 200th career sub-1:50 in the men's 800m, and he easily achieved that milestone behind Olympian Isaiah Jewett, who pulled away with 300m to go and won in 1:48.84 ahead of Sowinski's 1:49.38. Jamaica's Chrisann Gordon-Powell went through the first 400m in the lead in the women's 800m, passing that mark at 60.86, but Allie Wilson made a strong move and pulled away from the field over the final 200m to win in 2:03.87, more than four seconds ahead of the next finisher. Olympic champion Jasmine Camacho-Quinn and Tonea Marshall came to the first barrier even in the women's 100m hurdles but Camacho-Quinn clipped that hurdle and went down, leaving Marshall and a fast-finishing Tia Jones to dive at the line, with Jones winning by .01 in 12.84 into a slight wind. Opening his outdoor campaign with a win, Olympic champion and world record holder Ryan Crouser had five throws over 21m and came away victorious in the men's shot put with a fourth-round best of 21.63m/70-11.75. Triple jump American record holder Keturah Orji spanned a wind-aided 6.68m/21-11 on her first attempt in the women's long jump for the win, and in the women's hammer, Lara Boman had three throws good enough to win, hitting her best of 68.49m/224-8 in the fifth round. The cold and breezy conditions muted the vertical jumps. Vashti Cunningham cleared her opening height of 1.85m/6-0.75 on her first attempt and then needed three tries to navigate 1.90m/6-2.75, winning the women's high jump over Olympic teammate Rachel McCoy, who was clear through 1.85m before missing three times at 1.90m. Clearing 5.60m/18-4.5 on his second attempt gave Olympic silver medalist Chris Nilsen the win in the men's pole vault over Jake Wooten, who needed three attempts at that height before both men missed thrice at 5.70m/18-8.25. Olympic bronze medalist Alison dos Santos of Brazil sailed down the backstretch pushed by a strong wind and held a two-stride lead coming into the final curve. World leader Khallifah Rosser pulled up to his shoulder around the bend, with Olympian David Kendziera also in contention. Dos Santos made the best stretch run into the win to win in 48.41, with Kendziera second in 49.43 and Rosser third in 49.49.. Local favorite Jamal Britt, who competed for Iowa collegiately, had a slight edge through the first five hurdles in the men's 110m hurdles. He clipped the sixth barrier, allowing Olympic champion Hansle Parchment of Jamaica to move ahead and go on to win in 13.47, with Britt second in 13.53. New Zealand's Sam Tanner broke away from the field in the men's 1,500m after taking over the lead with 800m to go and never relented as he won in 3:41.28, almost four seconds ahead of Casey Comber in second. Laura Galvan of Mexico was a convincing winner in the women's 1,500m at 4:09.82.
In a matchup over 600m of current and former American record holders in the women's 800m, Olympic gold medalist Athing Mu powered away in the final 200m to clock the fourth-fastest time in history with a 1:22.74. Mu and Ajee' Wilson were side-by-side through the first 200m and hit the 400m mark together before Mu's surge. Jamaica's Natoya Goule passed Wilson down the final straight to place second in 1:24.09, making her the No. 9 performer all-time, with Nia Akins coming up for third in 1:25.14. Akins took over the No. 3 all-time U.S. outdoor performer slot and high schooler Sophia Gorriaran jumped to No. 4 with her 1:25.22. Dropping down to the sprint hurdles, Olympic 400m hurdles champion and world record holder Sydney McLaughlin got out with the field and pushed through the middle of her race to come away with a 12.75 win in the women's 100m hurdles, .42 seconds ahead of the runner-up. Running in front of the fans who hope to cheer him on as a member of the NFL Philadelphia Eagles this fall, Devon Allen improved his world lead to 13.11 in the men's 110m hurdles to turn back Jamaica's Omar McLeod, the 2016 Olympic champion and 2017 World Championships gold medalist. Nick Christie sliced more than five seconds off the American record in the men’s 5,000m race walk with a 19:23.30 that put him more than two minutes up on the next finisher. Christie bettered the AR of 19:28.66 set in 2003 by Tim Seaman. Better known as an 800m runner, Charlene Lipsey had a small lead in the women's 1,500m with a lap to go before former BYU teammates Anna Camp-Bennett and Whittni Morgan pushed to the front over the final lap and fought to the finish. Camp-Bennett had the fastest close and won by .1 seconds in 4:09.54. Wil London had the lead in the men's 300m coming off the turn before Nigeria's Chidi Okezie and Jamaica's Rusheen McDonald eased past him in the final 20m. Okezie outleaned McDonald for the win, 32.68-32.69. Taking advantage of a tangle between the leaders with 400m to go in the men's 600m, Ghana's Alex Amankwah held off Rajay Hamilton of Jamaica to win the men's 600m in 1:15.88.
