EUGENE, Ore. -- 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.
