Liu, the 2004 Olympic gold medallist, blasted out of the blocks and led from start to finish on Saturday with the help of a strong tailwind in front of a standing room crowd at Hayward Field.

American world indoor champion Aries Merritt finished second in 12.96, while Jason Richardson was third in 13.11 in a field that boasted hurdlers holding five of the top six times in the world this year.
