Olympic gold medalist Liu Xiang of China pulled away from Ladji Doucoure and Allen Johnson to win the 110-meter hurdles in the Prefontaine Classic on Sunday.

Liu, the co-world record-holder, won in 13.21 seconds, the fastest time in the event in this young season.

Doucoure, the Frenchman who won last year's world title, was a distant second at 13.33. Johnson, the 1996 Olympic gold medalist and four-time world champion, was third at 13.39.

The meet was held on a wet track after several days of bad weather, but the rain stopped just before the meet began.

In one of the best races of the day, reigning world champion Michelle Perry leaned in just ahead of Damu Cherry to win the 100 hurdles in 12.63 seconds, tying Priscilla Lopes of Canada for the fastest time in the world this year.
