World junior record holder Sydney McLaughlin upstaged Olympic champion Dalilah Muhammad to win her first senior women's 400 meters hurdles race at the Bislett Games on Thursday. McLaughlin made a poor start and clipped the first hurdle with her knee but took advantage after Muhammad, who appeared to be cruising, ran out of gas in the closing stages. The 19-year-old burst past three other runners including world champion Kori Carter to win in 54.16 seconds, ahead of fellow American Muhammad in 54.35. "It wasn't the cleanest race for me but I came back strong," McLaughlin said. "It was a sloppy race but I pulled through. I've got to work on my first half of the race, the second half is always my strongest." The men's 400 meters hurdles produced an outstanding run from world champion Karsten Warholm as the Norwegian won in a European record of 47.33 seconds to the delight of the home crowd. Warholm and Commonwealth champion Kyron McMaster were level after the fifth hurdle but the British Virgin Islander stumbled slightly as he landed and Warholm burst away. World record holder Beatrice Chepkoech was beaten in the home straight by fellow Kenyan Norah Jeruto who won the women's 3,000 meters steeplechase in a world leading time of nine minutes 03.71 seconds. World championship silver medalist Christian Coleman also set a world leading time as he won the 100 meters in 9.85 seconds, especially impressive in the cool conditions. "It was a good run and a pretty good time — now I'll look back at the video and critique it," said Coleman. "It wasn't ideal conditions but the crowd made it exciting." The American was quick out of the blocks and was so far ahead by the halfway point that it did not matter when he lost ground over the last few meters. Coleman timed 9.85sec with Xie Zhenye of China in second spot in 10.01sec and fellow American Michael Rodgers in third with a time of 10.04. Until Thursday, Coleman had shared a season best of 9.86sec with compatriot Noah Lyles and Divine Oduduru of Nigeria. Russia's Mariya Lasitskene, a two-time Olympic champion, dominated the women's high jump with 2.01m, a best for the season and her first height over 2m in 2019. It was her 34th career win against just one loss since the Rio Olympics of 2016, a tournament from which she was barred along with the entire Russian track and field team in the fall-out from the country's state-sponsored doping scandal. The 24-year-old's win came just three days after she called on officials implicated in the ongoing controversy at home to reform or quit. "All of these people think that athletes don't see or understand anything, and their business is only to jump and keep quiet," Lasitskene wrote in an unusually exasperated Instagram post. "I hope that people implicated in this never-ending shame spectacle find the courage to quit." — Agencies
