Tiger Woods carded a final round eight-under-par 64 to overcome Fiji's Vijay Singh and win the Williams World Challenge at Sherwood Country Club, Thousand Oaks.
Woods began the day four shots behind Singh but had 10 birdies, including five straight to start the back nine, and finished the event at 15-under (273).
Dubliner Padraig Harrington finished in 13th position on one over-par (289}, and fellow Irishman Darren Clarke finished second-last of the eighteen strong field on seven-over (295).
Singh struggled to a 71 in the final round and ended up alone in second on 12 under (276). No one else was within five shots of Woods, who invited 17 of the best players from around the world to an event that supports the children's foundation that bears his name.
Scott Hoch finished in third after shooting a final round 67 for a total of nine-under (279). German Bernhard Langer and American Mark O'Meara shared fourth on 281.
