Teenage sprinter Tate Taylor has completed a historic medal sweep at the World Under-20 Championships hosted at Hayward Field, Oregon.The 18-year-old American won 100m gold in a 9.94s personal best on Thursday, victorious by a tenth of a second over Gary Card (silver, 10.05s). He’s the first U.S. man to win that title since Noah Lyles, who did so in 2016.“Once I got out at the top end, I knew it was going to be a good race,” he told World Athletics media. “There were some tweaks I was looking to fix after the semi-finals, and I think I executed those pretty well.”Taylor followed that up with a storming 19.83s run for the 200m crown two days later, surpassing Lyles and all American men before him in an unprecedented double youth sprint gold. In still conditions, he won by nearly half a second ahead of compatriot Blake Hamilton (silver, 20.31s), bettering the championship record that Letsile Tebogo and Blessing Afrifah had jointly held from 2022 (19.96s).Then he closed out the championships by anchoring the U.S. men to 4x100m gold, running an 8.75s anchor split — the quickest in the field — to complete an under-20 world-record run by the quartet, who clocked 38.16s. In second were Great Britain, who set an age-group European record with 38.90s.Taylor is the first athlete in 40 years of the Under-20 World Championships to win the sprint treble. “It means a lot winning this gold medal,” he said. “We have been talking about this relay the whole week. We knew something special was about to happen. McDonalds’s, I am coming for you.”Team USA enjoyed a record-breaking championships on home soil, winning 24 medals total and 12 golds — bettering the Soviet Union’s 22 medals from 1988. Texas-born Mia Maxwell also claimed two individual sprint crowns (100m and 200m).“This double gold that Tate Taylor and Mia Maxwell just pulled off is probably one of the hardest to do,” wrote Lyles, the 100m Olympic and 200m world champion, on X. “Mostly because of how hard the schedule is. Six races in four days is so hard on the body. Then to do it as U20 athletes is even crazier.”Last week saw the end of a 23-race season for Taylor. He heads to Texas Tech to compete in the NCAAs from this September. Taylor also won 100m and 200m national age-group titles this year, and his standout win came at the Prefontaine Classic in early July, when he took down a senior 200m field in 19.75s, beating Tebogo in the process. Big personal bests this season means he is up to joint-fifth and third on the men’s under-20 lists for 100m and 200m respectively.
