EUGENE — Two world records and four American records brought down the curtain on a spectacular 2023 track and field season as the Wanda Diamond League Final was held before a loud and appreciative crowd at Hayward Field. It was the first time the event has been held in the United States, and the performances on Saturday and Sunday rank the Final as one of the greatest non-Olympic or World Championships meets in history. Two-time defending world champion Chase Ealey added the outdoor American record to her collection, blasting a 20.76/68-1.5 in the third round to seal her second straight Diamond League title and better the ratified shot put AR of 20.63/67-8.25 that was set by Michelle Carter to win the 2016 Olympic title in Rio. Ealey opened with a 19.77/64-10.5 and then unleashed a 20.61/67-7.5 on her next throw, the second-farthest effort ever by an American. Her throw was the best in the world since 2015. Maggie Ewen, who held the world lead coming into the meet, finished fifth with a best of 19.82/65-0.5. There's something about Hayward Field that agrees with Athing Mu. Undefeated in 10 previous races at the storied stadium, Mu once again came away victorious in the Prevagen Women's 800, bettering her own American record with a tactical masterpiece that saw her stop the clock at 1:54.97. Mu was content to run off the shoulder of Britain's Keely Hodgkinson for much of the race, but pushed past her in the final meters to cut .07 off the AR of 1:55.04 she set at the Pre Classic in 2021. Hodgkinson set a national record of 1:55.19 in second, and Jamaica's Natoya Goule-Toppin was third in 1:55.96, also a national record. Sage Hurta-Klecker was eighth in 1:59.65. A thrilling Nike Men's Bowerman Mile lived up to its billing with a homestretch battle between Norway's Jakob Ingebrigtsen and American indoor record holder Yared Nuguse that produced the third and fourth best times in history. Ingebrigtsen, the Olympic champion, stopped the clock at 3:43.73, missing the world record by only .6 seconds, and Nuguse was right on his shoulder as he shattered the ratified American record with a 3:43.97. Alan Webb set the AR of 3:46.91 in 2007 at Brasschaat, Belgium. The top 11 finishers all broke 3:50, with Cole Hocker scoring a lifetime best of 3:48.08 in sixth to move to No. 4 on the all-time U.S. performer list. One of the fastest men's 3000 races ever was decided by a lean at the line and produced a meet record 7:23.63 for Norway's Jakob Ingebrigtsen, the fastest time in the world since 1999 and the third-fastest ever. Ethiopia's Yomif Kejelcha set a national record 7:23.64 in second to move to No. 4 on the all-time world performer list. Grant Fisher lopped more than three seconds off his PB to clock 7:25.47 in third, bettering the ratified American record of 7:29.00 and moving to No. 8 on the world all-time performer list. History was made in the Nike Women's 5000 as Ethiopia's Gudaf Tsegay demolished the world record with a 14:00.21 that took almost five seconds off the WR that was set earlier this summer by Kenya's Faith Kipyegon. Runner-up Beatrice Chebet of Kenya clocked the third-fastest time ever with a 14:05.92. Alicia Monson was seventh in 14:45.98 and Weini Kelati took eighth in 15:25.62. Just as he did at last year's World Championships on the same runway, Sweden's Mondo Duplantis broke his own world record in the men's pole vault, this time negotiating 6.23/20-5.25 on his first attempt. Sam Kendricks took third at 5.72/18-9.25, with Chris Nilsen going over the same height for fifth. KC Lightfoot was seventh at 5.52/18-1.25. Running the second-fastest time in American history, Rai Benjamin defeated world champion and world record holder Karsten Warholm of Norway in the men's 400H, cruising past Warholm in the final 100 to clock 46.39. Benjamin's time is second only to his AR of 46.17 on the all-time U.S. performance list, and is the fourth fastest on the world all-time performance list. Warholm held on for second in 46.53 as Oregon22 bronze medalist Trevor Bassitt was eighth in 48.42 and CJ Allen ninth in 48.62. Matching his world-leading time set at the Xiamen Diamond League meet two weeks ago, 2019 world champion Christian Coleman won the men's 100 in 9.83 as the top four were within .04 seconds. World champion Noah Lyles closed swiftly and claimed second in 9.85, with Oregon22 silver medalist Marvin Bracy-Williams fifth in 10.01. World champion Katie Moon, who shared the gold at Budapest with Australia's Nina Kennedy, had to compete in a jump-off for the women's pole vault title and she came away with the victory over Slovenia's Tina Sutej after going over 4.86/15-11.25. Moon and Sutej had missed three times at that height in the regular competition to bring on the jump-off, and Sutej missed on her only attempt. Sandi Morris was third at 4.71/15-5.5. American record holder and Olympic champion Valarie Allman turned the tables on world champion Laulauga Tausaga-Collins in the women's discus, winning with her opening throw of 68.66/225-3. Tausaga-Collins produced a 68.36/224-3 in round three to make it a 1-2 U.S. finish, reversing the order from Budapest. last month. Reigning Diamond League Final champion, Joe Kovacs had his work cut out for him entering the shot put comp against world record holder Ryan Crouser. Kovacs came out strong, making a statement in round one with a 22.70/74-5.75 throw but Crouser quickly answered, putting a mark out at 22.91/75-2 in the second round. Kovacs unleashed a 22.93/75-2.75 in the fourth round that went unanswered and ultimately earned him his second-consecutive Diamond League Final trophy. In total, Kovacs landed five of six attempts over 22.50/73-10 - an incredibly consistent day for the shot put great. Another showdown in the men's 110H between three-time world champion Grant Holloway and reigning Olympic champion Hansle Parchment of Jamaica had the same outcome as in Tokyo, with Parchment moving past Holloway over the final three barriers to win in a world-leading 12.93. Holloway was second in 13.06, .01 ahead of Daniel Roberts. Freddie Crittenden notched a season best 13.15 in sixth, with Cordell Tinch seventh in 13.21 and Jamal Britt eighth in 13.36. World Championships bronze medalist Quincy Hall led a 2-3-4 American finish in the men's 400 with a 44.44, just ahead of Vernon Norwood's 44.61 in third. Bryce Deadmon placed fourth in 44.90. Nigeria's Tobi Amusan won the world title and set a world record on this track last year, and she continued her winning ways with a 12.33 in the women's 100H to beat Olympic champion Jasmine Camacho-Quinn of Puerto Rico. Keni Harrison, the American record holder and a bronze medalist at this year's World Championships, was third in 12.44, .04 ahead of Alaysha Johnson in sixth. 2019 world champion Nia Ali was seventh in 12.62, and Tia Jones placed ninth in 12.82.

In the women's 3000 steeplechase, Courtney Wayment was ninth in 9:20.69. Running in fine form this season, Shericka Jackson was aiming to break the world record in the women’s 200 to cap off the Diamond League season at Hayward. With just a +0.3 wind reading, Jackson took the trophy in a meet record 21.57 - shy of her personal best 21.41 in Budapest earlier this summer. TeeTee Terry was the top American in fourth, clocking a 22.21. Kayla White was sixth in 22.49 and Jenna Prandini came seventh with a 22.68. Reigning Olympic champion in the men’s 200, Andre de Grasse was after redemption following a sixth place showing in Budapest. He earned his trophy, running a season best 19.76 to take the title over an American trio of Kenny Bednarek, Erriyon Knighton, and Kyree King. Bednarek and Knighton went 2-3 in 19.95 and 19.97 with King close behind in 20.16 for fifth. A very fast opening lap in the men's 800 produced the fastest time in the world in 2023 as Kenya's Emmanuel Wanyonyi passed Canada's Marco Arop in the final meters to win in a meet record 1:42.80, .05 ahead of Arop.
