NEW YORK (AFP) — Sprint star Noah Lyles pulled up with cramp in the 200-meter final of the US athletics championships on Sunday, his bid for a title double undone as Garrett Kaalund claimed the victory.

Lyles, who won the 100m on Friday in a world-leading 9.79 seconds, pulled up as he came off the turn and jogged to the line, telling reporters he felt a grabbing sensation in his right thigh.

"I'm like, yeah, there's no reason to keep pushing that," he said. "I just decided to cut it off."

Fans at Icahn Stadium in New York were stunned, but the 2024 100m Olympic gold medalist downplayed potential injury concerns.

"It's just cramp. I've got some electrolytes here, I'm going to chug them down. I'm going to rest."

Lyles walked over to give Kaalund a congratulatory hug after the 22-year-old captured the title in 20.04 seconds.

"It's kind of crazy," Kaalund said.

Brandon Hicklin was second and Maximilian Thomas third, both credited with a time of 20.29 seconds.

Melissa Jefferson-Wooden, a treble gold medalist at last September's world championships, won the women's 200m in 21.69 seconds — just one-hundredth off her personal best.

Jefferson-Wooden came off the turn in front and powered home with Cambrea Sturgis second in 22.22 seconds and Camryn Dickson third in 22.58 seconds.

Jefferson-Wooden had opted out of the 100m, which was won by Sha'Carri Richardson.

In a year with no world championships or Olympic team berths on the line, some well-known names opted out of the national championships or tweaked their programs, but there were still plenty of familiar winners.

Tara Davis-Woodhall pushed her long jump winning streak to 19 competitions in dramatic style, unleashing a leap of 7.16 meters on her sixth and final attempt to triumph.

Davis-Woodhall hasn't lost in the event since a runner-up finish at the 2023 world championships, a streak that includes 2024 Olympic gold and last year's world title.

Her final jump carried her past Alyssa Jones, who settled for second on 6.96 meters, and Monae' Nichols, who took bronze in 6.92 meters.

"Today I was like, 'Let's try to do one and done, please," Davis-Woodhall said.

"And of course it never works out that way. It was a battle for sure."
