Four U.S. women tore through the water to a gold medal on Saturday in the 4x100-meter medley. Missy Franklin, Rebecca Soni, Dana Vollmer, and Allison Schmitt kept America’s winning streak afloat, securing their medal in the world-record combined time of 3:52.05. Australia came in second, and Japan took the bronze. It’s the fourth gold medal for the 17-year-old Franklin, and her fifth medal overall for these Games. Schmitt, another of the American team’s outstanding competitors in the London Games, will also go home with five medals. Moments later, the men's team won the same event, giving Michael Phelps his 18th career gold medal, likely his last before his announced retirement.
