Sanya Richards made a thrilling comeback from behind to anchor the win for the United States in the women's 4x400 meters relay at the Beijing Olympic Games on Saturday.

Richards, who finished a disappointing third place in the 400m event, overtook Russia's Anastasia Kapachinskaya at the last moment, to help the US quartet retain the champion won in Athens four years ago.

The US team, also including Mary Wineberg, Allyson Felix and Monique Henderson, clocked three minutes 18.54 seconds.

Russia took the silver in 3:18.82 and Jamaica won the bronze in 3:20.40.
