American Fred Kerley cramps up in 200-meter semifinal, finishers sixth to miss final at track world championships

EUGENE, Ore. — World 100-meter champ Fred Kerley will not have a chance at two individual medals at the world championships after he slowed down midway through his 200-meter semifinal due to a cramp and finished sixth.

The American, once a 400-meter specialist who moved down in distance before last year's Olympics, was holding his left hamstring Tuesday night after he crossed the finish line.

His departure in the 200 opens a less-challenging path for Noah Lyles, the defending world champion, 18-year-old Erriyon Knighton and top-ranked Kenny Bednarek, all of whom advanced. The trio had the top three times, led by Lyles at 19.62 seconds.

Later Tuesday, Alison Dos Santos of Brazil powered down the homestretch to take the 400-meter hurdles title.

The underdog even if he had the fastest time and No. 1 ranking coming in, Dos Santos held off a decorated field that included the world-record holder. Dos Santos finished in a championship-record time of 46.29 seconds. Americans Rai Benjamin and Trevor Bassitt won the silver and bronze.

Olympic champion and world-record holder Karsten Warholm of Norway has been dealing with hamstring issues and didn't have his trademark kick at the finish. He wound up seventh.

Upon his finish, Dos Santos gave two bows to the cheering crowd. He broke Kevin Young's world-championship record of 47.18 seconds set in 1993 in Germany. Dos Santos won bronze at the Tokyo Games last summer behind Warholm and Benjamin.

Indeed, it was a night full of surprises, with Jake Wightman of Britain winning the 1,500 meters. He had a look of disbelief as he crossed the
