The United States went 1-2 in the men's 110-meter hurdles final Wednesday at the 2012 Summer Olympics in London. Aries Merritt won the gold medal with a time of 12.92 seconds and Jason Richardson took silver just 0.12 seconds behind to give Team USA a big boost in the overall medal count.

Merritt led from the outset of the race and held on for the win, but Richardson needed to come from behind on the final set of hurdles to pass Jamaica's Hansle Parchment. Parchment set a Jamaican record, running 13.12 seconds to take home the bronze medal.

Dayron Robles of Cuba, the defending Olympic gold medalist, did not finish the race after apparently pulling a muscle in his leg midway through the run. Great Britain's Lawrence Clarke took fourth and Ryan Brathwaite of Barbados finished fifth.
