The United States set a world record to win the women's medley relay at the London Olympics on Saturday.
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 staked them to a lead that was never in danger, as Rebecca Soni, Diana Vollmer and Allison Schmidtt all won gold again.
The 17-year-old Franklin, who starts her senior year in high school this fall, 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.
