NEW YORK (REUTERS) - Olympic shot put champion Ryan Crouser of the United States set a indoor world record of 22.82 metres at the American Track League series opener in Fayetteville , Arkansas on Sunday (Jan 24).

On his opening attempt, Crouser, who won the gold medal at the 2016 Rio Olympics, bettered the 32-year-old mark of 22.66m set by fellow American Randy Barnes in 1989.

The 28-year-old also bettered the old world record on his third attempt with an effort of 22.70m.

Crouser finished off the meet with a throw of 22.48m, his third-best of the day, but still a mark that only two other men have ever bettered indoors.

"It's a pretty good start to 2021," he said.

Grant Holloway, the 110m hurdles world champion, showed good early-season form, equalling his US 60m hurdles record with a dominant run of 7.35 seconds, while former world indoor 60m champion Trayvon Bromell won his sprint in 6.58 seconds.
