San Antonio, TX (SportsNetwork.com) - Steven Bowditch carded a 4-over 76 on Sunday, but that was good enough for him to hang on and win the Texas Open.

Bowditch earned his first career victory on the PGA Tour at 8-under-par 280.

"I'm over the moon. I really can't believe it yet," Bowditch said about his maiden win.

Will MacKenzie (70) and Daniel Summerhays (71) shared second place at 7-under, while Matt Kuchar and Andrew Loupe shot matching 3-over 65s at blustery TPC San Antonio to fall into a tie for fourth at 6-under 282.

Zach Johnson (72), Jim Furyk (71), Jerry Kelly (71) and Brendon Todd (68) shared sixth at minus-5.

Bowditch entered the final round with a 3-stroke lead, but quickly gave that advantage away when he followed a bogey at the second with a 3-putt double- bogey 6 at the fourth, dropping him to 9-under and into a tie with Kuchar.

A 2-stroke swing at the fifth put Bowditch back on top, however, as Kuchar tripped to a bogey at the hole and Bowditch converted a 5-foot birdie putt to get back to 10-under.

Bowditch would give that shot right back with a bogey at the sixth, and Kuchar recovered from his gaffe with a 19-foot birdie putt at the eighth to again grab a share of the lead.

But Kuchar would 3-putt for bogey at the 10th before dropping another shot at the 11th to fall two shots off the pace.

After Bowditch 2-putted for bogey from inside 10 feet at the 13th to cut his advantage to one, Summerhays converted a 9-foot birdie putt at the 14th to meet Kuchar in second at minus-7.

MacKenzie would make it a three-way tie for second with a birdie at the 17th before Kuchar bogeyed the 14th to drop to 6-under. Kuchar would par his final four holes to end there.

Summerhays traded a bogey at the 15th with a birdie at the 16th to also finish at 7-under.

Bowditch, meanwhile, stuck his third shot at the par-5 14th to two feet and kicked in that shot birdie to regain his 2-stroke cushion.

That shot would be needed, as Bowditch found the thick rough to the left of the fairway with an errant drive at the 18th, but was still able to 3-putt for bogey and the win.

"I just drew back on some experience and got some advice through some different people," Bowditch said about his approach throughout the day. "It just happened to be my week I guess."

NOTES: Bowditch earned his first career win in his 110th start on the PGA Tour ... Bowditch's 76 was the highest score by a winner since Vijay Singh also posted a 76 at the 2004 PGA Championship ... Loupe finished inside the top 10 for the first time in his career ... Kevin Na was assessed a 2-stroke penalty for testing conditions in bunker at the fifth hole, resulting in a triple bogey.
