EUGENE, Ore. (AP) Kaylin Whitney of Florida overcame a yellow card to win the 200 meters Friday night in the IAAF world junior championships at Hayward Field.
The world youth record holder in the event, Whitney was shown a yellow for what appeared to be a false start but she was not disqualified, going on to win in a wind-aided 22.82 seconds. At 16, she became the youngest gold medalist at the international event that runs through Sunday.
''There was an issue with the blocks, but I knew it would be OK because I was here for a reason,'' she said.
This month at the U.S. junior championships, the 16-year-old broke the world youth record in 22.49, besting the 17-and-under mark of 22.58 set by Marion Jones in 1992. This week at the worlds, the incoming junior at East Ridge High School in Clermont, Florida, claimed the bronze medal in the 100.
The U.S. team got another gold with Trentavis Friday's wind-aided 20.04-second victory in the men's 200. Friday is an incoming freshman at Florida State.
''It was windy today but I just wanted to try to win the race,'' he said. ''Time didn't matter, fast is fast and I just wanted to win today.''

Jaheel Hyde of Jamaica ran away with the 400 hurdles in a personal-best 49.3. It was the best junior time in the event this year. Last year he won the 110 hurdles at the junior worlds.
''My aim was to win the world juniors. I started training back in January with this goal in mind,'' Hyde said. ''I executed my race well today and I'm very happy with the victory.''
