SAN ANTONIO: Zach Johnson won the Texas Open on Sunday for his fourth PGA Tour title, following his third-round 62 with a 64 for a two-stroke victory over Charlie Wi, Mark Wilson and Tim Wilkinson.

Johnson, the 2007 Masters champion who entered the week with only one top-10 finish this year, had a 19-under 261 total on the LaCantera Golf Club’s Resort Course.

“This hasn’t been the best year for me,” said Johnson, who earned $810,000. “It’s been a long time coming,” he added.

The victory, capped with a 5-foot birdie putt on 18, was his first on the tour outside Georgia. In addition to the Masters, he won the 2004 Bell South Classic and 2007 AT&T Classic.

Wi finished with a 61, Wilson had a 63, and Wilkinson shot a 64. Wi parred the final two holes.

“I didn’t look at the score board until I got to the 15th hole. I knew Zach was close, but I was playing very good,” Wi said. “I was very happy to make those birdies on 15 and 16. I wish I could have made one more,” he explained.

Third-round leader Rory Sabbatini shot a 72 to finish seven strokes back at 12 under. “I’ve been working on my putting over the last six weeks with my teachers and it really paid off this week,” Johnson said.

He never trailed on the back nine, but both Wi and Wilkinson keep the pressure on with birdies putts of their own.

On the par-4 18th hole, Johnson hit his drive more than 300 yards and put his 9-iron approach to 5 feet.

The ensuing walk up the 18th fairway was a filled with smiles and waves for the crowd, while his wife and young son waited behind the green. “Hopefully this is the first of many to come,” Johnson said.
