Veriato shot his third straight 4-under-par 68 Sunday to become the third first-time winner on the Senior PGA Tour in as many weeks.
'I never thought I'd win, even though I always knew I could win,' Veriato said, choking back tears. 'Sometimes, you play your very best and people beat you. That's how good the competition is out here.'
The victory was worth $225,000 for Veriato, who finished at 12-under 204.
Home-state hero Bruce Summerhays, the second-round leader was followed by a gallery of family and friends on Sunday. He faltered with a crippling double-bogey on the par-5 17th after hitting his tee shot out of bounds.
'It's disappointing because I was playing for the fans. I think they'll be more disappointed than me,' he said. 'My Aunt Elaine is just crying her eyes out right now.'
Bruce Lietzke, Graham Marsh, Jesse Patino and Tom Jenkins finished one stroke behind Veriato, while Summerhays and Walter Hall finished at 10-under.
