American David Oliver avenged a May loss to former Olympic and world champion Liu Xiang of China with a 2011-leading time of 12.94 seconds in the 110 meters hurdles at the Prefontaine Classic Diamond League Meet on Saturday.

Liu came second in 13 seconds flat with American Aries Merritt third in 13.18. Liu, the former world record holder, appeared to take advantage of his new starting technique to take the early lead over Oliver. By the third hurdle, however, the American record was in command.

Liu, who his coach says still feels foot pain from a 2008 surgery, had beaten Oliver by clocking 13.07 seconds in Shanghai to snap the American's 18 race win streak. Liu said he is happy with his time, but expressed disappointment with his finish.
