OSAKA, Japan -- Tyson Gay collected a third gold medal at the world championships when he helped the United States win the 4x100-meter relay Saturday in 37.78 seconds.
Gay ran the third leg on the bend and handed off to Leroy Dixon, who held off world record holder Asafa Powell on the straightaway.
Powell's Jamaicans were second in a national record 37.89 and Britain was third.
Gay won the 100 and 200 sprints. The relay title makes him only the third man to win triple golds at a single world championships meet.
Carl Lewis did it in 1983 and 1987, combining the 100, 4x100 relay and long jump. Maurice Greene did it in 1999 at Seville, winning the 100, 200 and relay.
Defending champion France did not compete.
