EUGENE — Meet records in three events and thrilling finishes in four others elicited roars from a raucous crowd Monday night on the fourth day of the U.S. Olympic Team Trials - Track & Field at Hayward Field. Shattering a meet record that had been tied in Saturday's semifinal, the first eight men across the line in the 1500 bettered the previous standard, led by Cole Hocker's stunning 3:30.59 that was a personal best and made him the No. 6 all-time U.S. performer. American mile record holder Yared Nuguse set a sizzling pace through the first 400, going by in 56.32, and he continued to lead through 800 in 1:55.30 and 1200 in 2:51.33 with a large group on his heels. Into the final backstretch Hocker started to move up on his shoulder and then went to the front with 200 to go. Hocker held on around the final bend and sprinted to victory with Nuguse running a season best 3:30.86 and World Road Mile champion Hobbs Kessler grabbing third in a PB 3:31.53. Vincent Ciattei made a strong move down the stretch to try and overtake Kessler but ended up an agonizing fourth in a big PB of 3:31.78. Elliott Cook of Oregon was eighth in 3:33.84, making it the deepest all-American race in U.S. history. The previous Trials record of 3:34.09 was set by Mathew Centrowitz in 2016 and tied by Nuguse in the semis. The second meet record on the oval came out of a frenzied push for the finish between Elle St. Pierre and defending USATF champion Elise Cranny. St. Pierre, who set an American record in the mile earlier this year and won the World Indoor 3000 title in March, outleaned Cranny for the victory in 14:40.34 to break the previous standard of 14:45.35 set in 2000 by Regina Jacobs. Cranny was only .02 behind St. Pierre, and Karissa Schweizer completed the Paris squad with a third place 14:45.12. NCAA 5000/10,000 champion Parker Valby of Florida made the early pace, going right to the front and pulling the field through 1K in 3:00.23, 2K in 5:58.89 and 3K in 8:57.57. At 4K, St. Pierre and Cranny were less than a half-second behind Valby in 11:56.14. Through the final kilometer the more experienced trio of St. Pierre, Cranny and Schweizer surged past Valby on the way to making the team, but Valby stayed in sight and set a PB of 14:51.44 in fourth. American record holder Valarie Allman was one and done in the qualifying round of the women's discus, breaking her own meet record with a massive 70.89/232-7 on her first attempt, the best throw by an American this year and the third best throw ever by an American. Four other women bettered 61m, but last year's World Championships gold medalist Laulauga Tausaga-Collins had three fouls and did not advance to the final. A dramatic fall by American record holder and reigning Olympic champion Athing Mu just before the 200m mark took her out of contention in the women's 800, leaving the way open for Nia Akins to defend her USATF title with a PB 1:57.36. Allie Wilson had the fastest final 100 to claim the runner-up spot in 1:58.32, and the NCAA indoor and outdoor champion Juliette Whittaker of Stanford had a PB 1:58.45 to take third. LSU's Michaela Rose took the field past 400 in 57.68 but couldn't match the closing speed of the first three and placed fourth in 1:59.32. Budapest heptathlon silver medalist Anna Hall proved she is back from injury and surgery, closing out a 6,614-point performance with a stellar 2:04.39 in the 800 after a season best 45.57/149-6 in the javelin. The race for the other two Paris places came down to a scintillating contest between Chari Hawkins, Taliyah Brooks and Michelle Atherley. Entering the final event the trio was in that order in the point standings, and despite a titanic effort by Atherley to set a PB 2:06.68, she fell 17 points short of making the podium and the Paris team. Hawkins struggled to the finish with the fastest time she had ever run, a 2:14.76 that secured the runner-up spot with a PB 6,456, and Brooks also had a PB of 2:13.39 to tally a lifetime best 6,408 in third. Last year's World Championships bronze medalist Quincy Hall made the most of the gentle turns in lane eight of the men's 400, slicing his PB to 44.17 for his first Trials title, defeating 2022 world champion Michael Norman, who was second in 44.41, and Olympic debutant Chris Bailey, who placed third in 44.42. Maryland teenager Quincy Wilson, a 16-year-old who set a pair of high school national records in the heats and semifinal, couldn't match those times but still finished a respectable sixth in 44.94. Field event titles went to Kentucky's Charity Hufnagel in the women's high jump and Florida State's Jeremiah Davis in the men's long jump. Hufnagel sailed over a PB 1.94/6-4.25 to break Vashti Cunningham's six-meet USATF Championships winning streak, with Rachel Glenn of Arkansas negotiating that same height for second and Cunningham finishing in a tie with Nebraska's Jenna Rogers for third at 1.91/6-3.25. Cunningham won an administrative jump off with Rogers for the third position in the Paris team calculations. Davis had a round three leap of 8.20/26-11 and held on for the win over a pair of 8.18/26-10 jumpers, Malcolm Clemons of Florida and 2017 World Championships silver medalist Jarrion Lawson. None of the athletes in the final have achieved the Olympic qualifying standard. Reigning Trials champion Grant Holloway, the three-time defending world champion in the men's 110 hurdles, skimmed the 42-inch barriers to win his heat in 12.92, equaling the seventh-fastest time in U.S. history. Jamal Britt dropped his PB to 13.07 for the second fastest time overall. In the women's 3000 steeplechase first round, Gabbi Jennings was the fastest overall at 9:23.88 to qualify for the final and there were no notable casualties. Following two off days, the Trials resume Thursday. Full results are available here.
