Steven Bowditch held on to win the Texas Open in windy conditions Sunday for his first PGA Tour victory and a spot in the Masters.

The 30-year-old Australian bogeyed the par-5 18th for a 4-over 76 -- the highest closing score by a winner since Vijay Singh finished with a 4-over 76 in the 2004 PGA Championship -- for a one-shot win.

"I'm over the moon. I can't believe it," said Bowditch, who finished at 8-under 280 at TPC San Antonio and earned $1,116,000.

Will MacKenzie (70) and Daniel Summerhays (71) tied for second place. Matt Kuchar (75) and Andrew Loupe (75) shared fourth at 282.

Bowditch, who has fought depression during his golfing career and attempted suicide in 2006, had only two top-10 finishes in eight years on tour.

He played the front nine in 3-over 39, making a double bogey on the par-4 fourth. He countered a bogey on 13 with a birdie on the par-5 14th and made three pars before missing a 3-foot par putt on 18.

"Every time I got out of check, looking ahead to the Masters and winning golf events and making my speeches before I was finished, I had to pull myself in check every time," he said. "And it happened a lot today."

LPGA: Laura Diaz had a hole-in-one for the second straight day to join Jenny Lidback (1997 Tournament of Champions) as the only tour players to make two aces in a tournament.

She aced the par-3 third hole in the third round of the Kia Classic in Carlsbad, then holed out on the 157-yard sixth hole Sunday with a 6-iron.

"I went out today hoping I could get another one," she said. "Just really using my head to see how wild and crazy it could get. Then it happened and I went nuts. It's pretty crazy."

She also eagled the par-4 seventh Sunday, holing out from 122 yards with a wedge. She closed with a 2-under 70 to finish at 2-under 286 at Aviara.

Anna Nordqvist shot a final-round 5-under 67 and rallied to win by one stroke over Lizette Salas. It was Nordqvist's second victory in her last four tour starts. She finished at 13-under 275 and earned $255,000.

Salas birdied the 18th for a 70.
