MODESTO, California: Greg Henderson of New Zealand powered to a surprising stage win and took the overall race lead at the Tour of California from British teammate Ben Swift in the wind-filled and crash-marred third stage Tuesday. Team Sky rider Henderson, usually the main lead-out rider for Swift, went to the front with about 500 meters left, and took the 121.9-mile Auburn to Modesto road race in 5 hours, 14 minutes and 29 seconds. Swift is second, with Peter Sagan (Liquigas-Cannondale) of Slovakia, third overall, trailing by 4 seconds.
