Zhang took silver with 445.90 points and Matthew Mitcham of Australia was third with 440.20. Qin won gold at last year's Beijing Olympics with Wang Feng in 3-meter synchronized and took bronze in 3-meter springboard. He also won two golds at the last worlds in Melbourne, Australia, two years ago. Qin took control with his fifth dive, a reverse 2½ somersault pike that earned 8.5's and 9's.
