    WASHINGTON, Aug. 2 (Xinhua) -- World number one Tiger Woods lifted his 69th PGA Tour title on Sunday as the American seized the Buick Open.

    Woods clinched a three-under 69 on Sunday after finishing at 20-under 268, leading Roland Thatcher by three shots who fired a 64. Greg Chalmers (68) and John Senden (70) followed in third and fourth places.

    It was Woords' third victory in the Buick Open and fourth this season.

    On Sunday, he chased down and caught Thatcher who finished in a much earlier group.

    Woods made a birdie at number four to take the sole lead and he doubled his lead with a short birdie putt on number seven.

    His ball landed behind a tree at the par-five 13th. He needed something special to reach the green in two. But his next shot landed in the water.

    Taking his drop about 60 yards from the hole, Woods rolled his fourth shot within three feet of the hole and eventually made par.

    He posted a birdie on 16 to seize a three-shot lead. That ended his streak of eight-straight pars.

    Woods parred the final two holes to add to his wins at Warwick Hills in 2002 and 2006.
