(CNN) -- Tiger Woods seized the lead late in the final round and held on to win on Sunday at the AT&T National in Maryland.
Tiger Woods waves to the crowd on Sunday on the 18th hole at the AT&T National.
The world number one sank a 20-foot birdie putt on the 16th hole, and parred out the remaining two holes to defeat Hunter Mahan by a stroke and challenger Anthony Kim by four.
The tournament prize was Woods' 68th career victory.
Sunday's final round had been billed as a showdown between Woods and Kim, a challenger many golf analysts have projected as being a possible successor to Woods as the world's top-rated golfer. The two were tied going into the final round.
But after an opening-hole birdie, Kim could not mount a challenge as he finished with a lackluster final round of 71.
Instead it was Ryder Cup man Mahan who provided the main opposition as he emerged from the pack with an eight-under 62 to equal Kim's course record set on Thursday and set the clubhouse pace on 12-under.
Woods, who is warming up for the third major of the season, the British Open at Turnberry next week, made his move in the final round with three birdies in five holes to move well clear of partner Kim.
But with Mahan carding six birdies on the back nine there was still work to be done and Woods duly obliged on the 16th.
Bryce Molder carded a 68 to finish in fourth to clinch a qualifying spot for the British Open. The other spot from a special money list went to Paul Goydos.
Brandt Snedeker finished tied for fifth with U.S. Open champion Lucas Glover.
