ORLANDO, Fla. -- Tiger Woods began his march to the Masters with his first victory of the year, a four-shot margin at the Bay Hill Invitational on Sunday that was secured by Phil Mickelson's blunders on the closing holes.

Trailing Mickelson by one stroke at the turn, Woods played mistake-free when the pressure was at its peak and closed with a 3-under 69 to become the first player to win Arnold Palmer's tournament three years in a row.

Woods finished at 275 and won for the 30th time in his career. At age 26, he is the youngest player in PGA Tour history to reach that benchmark.

He also became the first player to make it three in a row at three PGA Tour events, having already completed the hat trick at Firestone and the Memorial Tournament.

Mickelson closed with three straight bogeys and finished at 71, in a tie for third, five strokes behind.

Michael Campbell of New Zealand holed a 42-foot chip on the 18th for birdie to close with a 71 and finish second at 279, his best finish ever on the PGA Tour.

Siebel Classic

SAN JOSE, Calif. -- Dana Quigley made a 10-foot par putt on the final hole, holding off Fuzzy Zoeller and Bob Gilder for a one-stroke victory at the rain-soaked Siebel Classic in Silicon Valley.

With a 1-under 71 in the final round, Quigley got his sixth Senior PGA Tour victory. He finished at 4-under 212.

Gilder also shot a 1-under 71, while Zoeller, playing in his sixth senior tournament, had a 2-under 70.

Ping Banner Health

PHOENIX -- Rachel Teske birdied the second playoff hole to beat defending champion Annika Sorenstam in the Ping Banner Health.

Sorenstam blew a four-shot lead in regulation. She started with a double bogey on the first hole and had bogeys on the last two, finishing at 4-over-par 76.

Teske carded a 71, tying Sorenstam at 7-under 281.
