BRUSSELS — Fred Kerley wrote his name in the Diamond League record book and three Americans had impressive wins in the penultimate meeting of the World Athletics series at King Baudouin Stadium. Team USATF swept the top three spots in the men’s 100m, with Tokyo silver medalist Kerley winning in 9.94 over Trayvon Bromell’s 9.97. World Athletics noted that Kerley became the first man ever to win a 100m, 200m and 400m in the Diamond League. Michael Norman, dropping down from the 400m, clocked 9.98 for third, a season best and the second time in his career he has broken 10 seconds. Bromell and Kerley were out well and were even until the final meters, where Kerley eased ahead, and Norman closed well. Coming off a win at Rovereto three days ago, Olympic fourth-placer Michael Cherry smashed his lifetime best to run away with the men’s 400m title, breaking the meet record with a 44.03 that put him well clear of Tokyo bronze medalist Kirani James of Grenada. Cherry quickly made up the stagger on the athlete to his outside, with James stalking him from one lane inside, but Cherry pulled away over the final 100m for his fourth personal best of 2021. He broke the meet record of 44.06, set in 1998 by Michael Johnson. Winning his first Diamond League title, Steffin McCarter used a 7.99m/26-2.75 in the sudden-death sixth round of the men’s long jump to come away with victory. McCarter had hit 7.93m/26-0.25 on his first jump and was two centimeters behind South Africa’s Ruswahl Samaai going into the winner-takes-all final where marks from the first five rounds were erased. Samaai could manage only 7.89m/25-10.75 on his sixth jump and ended up second. In the women’s discus, which was held at a city park on Wednesday, Valarie Allman finished second with a best of 64/25m/210-9. Allman’s mark actually placed her third overall, but a sixth-round 63.38m/207-11 gave her the runner-up spot in the Diamond League sudden death format. A first-attempt clearance at 5.85m/19-2.25 gave Chris Nilsen a second-place finish in the men’s pole vault ahead of fellow U.S. Olympian KC Lightfoot, who matched his outdoor personal best at that height but required three tries to go over. Both men missed three times at 5.91m/19-4.75. Moving to No. 10 on the all-time U.S. comprehensive performer list, Elise Cranny finished fifth in the women’s mile with a lifetime best 4:21.90, just ahead of Josette Norris, who took sixth in 4:22.71, also a personal best. Set up as an attempt at the world record by Sifan Hassan of the Netherlands, the race was really run in two parts -- Hassan vs. the clock and then the rest of the pack. Hassan won in 4:14.74, the fifth fastest outdoor performance ever, and was more than six seconds ahead of the runner-up. Chopping almost six seconds off her lifetime best, Alicia Monson moved to No. 4 on the all-time U.S. performer list in the women’s 5,000m with a 14:42.56 that placed her ninth. Monson was hanging on to the back of the lead pack with three laps to go, but an injection of speed by the front four dropped her over the next two laps and she was alone in ninth as she finished well to maintain her U.S. lead in 2021. Other action on the track included Sha’Carri Richardson, who was in contention for a top-three finish in the women’s 200m but lost some ground in the final quarter of the race to end up fourth in 22.45, and Gabbi Cunningham, who placed fifth in the women’s 100m hurdles in 12.89. Kate Grace was fifth in the women’s 800m in 1:59.22.
