Missy Franklin helps U.S. women set world record in 4x100 relay at 2012 Summer Olympics
Franklin, swimming the backstroke, gave her team the lead in the first leg with the U.S. finishing the relay in 3 minutes, 52.05 seconds. The previous record was set by China in 2009 with a time of 3:52.19.
The medal is the fifth for both Franklin and Schmitt from the 2012 Games. Franklin, 17, also set a world record Friday in the 200 backstroke.
