David Zabriskie won his fifth US professional cycling time trial title in Greenville, South Carolina on Saturday. Zabriskie won the crown by 31 seconds, completing the 20.7-mile course in 40 minutes, 23.5 seconds. He won four titles in a row from 2006 to 2009 but didn't compete last year. Last year's winner, Taylor Phinney, finished 50 seconds adrift in seventh place.
Tom Zirbel was second, Matthew Busche finished third and Brent Bookwalter finished fourth after three laps of the 6.9-mile circuit. The 112-mile US road race championship is on Monday, America's Memorial Day holiday. Ben King will try to defend his title against Zabriskie and other top Americans including George Hincapie.
