LONDON (AP) — The United States set a world record to win the women's medley relay Saturday at the London Olympics.

The Americans clocked 3 minutes, 52.05 seconds, slicing 0.14 off the previous mark set by China at the 2009 world championships at the height of the high-tech bodysuit era.

Missy Franklin swam the leadoff backstroke leg, Rebecca Soni did the breaststroke, Dana Vollmer competed in butterfly and Allison Schmitt had the anchor leg in freestyle.

Franklin finished the meet with four golds and a bronze, while Schmitt leaves with three golds, a silver and a bronze.

Australia touched in 3:54.02 to take the silver medal and Japan finished in 3:55.73 to take bronze.
