EUGENE, Oregon (AP) -- Sixteen-year-old American Kaylin Whitney won the 200 meters Friday at the world junior athletics championships.
Whitney was shown a yellow card for what appeared to be a false start but was not disqualified, going on to win in a wind-aided 22.82 seconds. She is the youngest gold medalist so far at the international event that runs through Sunday.
Whitney broke the world youth record in 22.49 this month at the U.S. junior championships, besting the 17-and-under mark of 22.58 set by Marion Jones in 1992.
She claimed the bronze medal in the 100 meters at the worlds earlier this week.
The U.S. team got two more golds with Trentavis Friday's victory in the men's 200 in a wind-aided 20.04 seconds and Kendall Baisden win in the women's 400 in 51.85.
Jaheel Hyde of Jamaica ran away with the 400 hurdles in 49.30 seconds, the best junior time in the world this year. Last year, he won the 110 hurdles at the junior worlds.
Yomif Kejelcha of Ethiopia won the men's 5,000 in 13 minutes, 25.19 seconds.
Ashraf Amgad Elseify of Qatar won the men's hammer with a throw of 277 feet, 11 inches, while Brazil's Izabela Da Silva won the women's discus with a throw of 190 feet, 4 inches.
It is the first time the junior world championships are being held in the United States. Nearly 1,600 athletes from 170 countries are taking part in the event, which includes only athletes born between 1995 and 1998.
