Watch the men's relay team of Michael Phelps, Garrett Weber-Gale, Cullen Jones and Jason Lezak win gold in an exhilarating 4x100-meter freestyle race. With a time of 3:08.24, the team shattered the previous world record of 3:12.23, set by Team USA in the prelims. The Americans won by a margin of only 0.08 seconds — a win that kept Phelps' hopes of winning eight gold medals alive. In his fifth Olympic appearance, Phelps will go after three more individual gold medals in Rio.
