'It feels awesome,' said Driscoll, who climbs to ninth on the Nationwide Tour money list with the $81,000 he earned for the win. 'This is such a weird game. Nothing is guaranteed. There are no contracts. You never know when you'll get it going.'
Overnight leader Tim Simpson struggled to a 2-over 74 in the final round and tied for second place with Jason Buha and two-time winner this season Jimmy Walker, both of whom shot 68s on Sunday. The trio was knotted at 11-under-par 277.
Driscoll started the final round two shots behind Thompson, but erased the gap quickly with two birdies in a three-hole span from the third. He dropped a stroke to par at the par-3 seventh, but atoned for the miscue with an eagle at the par-5 eighth.
'The first nine holes I didn't know where the ball was going. It was all over the place,' said Driscoll. 'The front nine I don't think I hit one really decent shot.'
Driscoll bogeyed the 10th hole, but Thompson helped Driscoll's rise to the top of the leaderboard. Thompson bogeyed the 12th and 13th holes and Driscoll birdied 12 and 15 to take a commanding lead.
Thompson clawed to within two thanks to birdies at 14 and 16. The margin was two strokes when the pair played 18. Thompson made double bogey and Driscoll took a par for the four-stroke victory.
'Those two holes were huge,' said Driscoll referring to the 12th and 13th. 'Kyle had some terrible luck and got an awful lie on 12 and made bogey and then made another one on the next hole where I made a ridiculous sand save.'
This was Driscoll's first victory on the Nationwide Tour. His best finish was a second at this year's Northeast Pennsylvania Classic when D.A. Points beat him in a playoff.
Most golf fans remember Driscoll as the player who was runner-up to Jeff Quinney at the 2000 U.S. Amateur Championship.
