Wagner leads Houston Open by one shot

HOUSTON, Texas (Reuters) - Johnson Wagner, aiming for his first PGA Tour victory, shot a three-under-par 69 to take a one-stroke lead over Chad Campbell after the Houston Open third round on Saturday.

Wagner, ranked 313th in the world, finished with a 15-under total of 201 as he chased the first prize of $1 million and a win that would earn a spot at next week's U.S. Masters at Augusta.

Campbell, wielding a hot putter, was tied for the lead before a bogey at the par-four 17th prevented him registering a second successive 64. His 65 put him on 202 at the Redstone Golf Club.

Campbell birdied three of the first four holes and rolled in a 60-footer for birdie at the sixth. The 2003 Tour Championship winner added an eagle at the par-five eighth hole when he spun an 88-yard wedge shot back into the hole.

Bob Estes, who fired a bogey-free 64, and Charley Hoffman (69) were tied for third on 204.

None of the top four have yet qualified for the Masters, the year's first major.

Geoff Ogilvy, the 2006 U.S. Open champion, posted a 66 for 206 while fellow Australian Mathew Goggin carded a 72 for 207.

The 28-year-old Wagner said he had some good fortune.

"(I) got a couple of great breaks off the tee on the par-fives on the back nine," Wagner told reporters. "I think I hit a spectator and kept it in play. Knocked it off a tree, came back into play.
