DEBRECEN, HUNGARY - Stephanie Smith set a meet record with her 52.19 clocking in the 400 meters here Saturday at the IAAF World Youth Championships to lead a 1-2 U.S. sweep in the event. Smith, a Macon, Ga., high schooler, broke the old meet record of 52.29 set by Monique Henderson of the U.S. in 1999. Texas high schooler Jerrika Chapple won silver behind Smith with a season-best 52.80.

"I ran a personal best," Smith said. "That was a surprise because I am still tired from our trip over here. We arrived very late and I haven't yet adjusted to the time difference. I don't care about that now, though, because I won the World Championships and nothing else matters now. There's a lot of room for improvement left for me."

Another Georgia prep picked up silver in the men's 400 hurdles, where Ellenwood's Jonathan Walker ran a personal best of 51.32 to take second.

Michelle Carter, daughter of NFL All-Pro defensive tackle and 1984 Olympic silver medalist Michael Carter, set a personal best of 15.23/49-11.75 on her sixth and final attempt to win silver in the shot put.

With one day remaining in the meet, Team USA has already surpassed its performance in the inaugural World Youth Championships, winning ten medals, versus seven in 1999.
