David Boudia used to be scared to dive off the 10-meter platform. Yet when it counted most, he never flinched. The American plunged off the 33-foot tower, somersaulting and twisting over and over on his last dive to win an Olympic gold medal by 1.80 points over Qiu Bo of China on Saturday night in the closest men's platform contest since 1988. Boudia's victory gave the U.S. its first gold in diving since 2000, and was the first by an American man since the late Mark Lenzi won the 3-meter springboard at the 1992 Barcelona Games.
