The end was not without controversy, however. Weibring rolled his birdie putt within a few feet of the cup at the last. As he took his back swing to tap the ball in for par, the ball oscillated briefly.
Weibring tapped in, without stopping, for his par. He mentioned to playing partner Tom Kite and a rules official that the ball had moved in his back swing.
The rules official watched replays of the putt and determined that Weibring never grounded his club, therefore there was no penalty assessed and the victory was his. Weibring became the 14th different winner in the event's 14 years.
'I had to add a little drama for our last trip around this golf course,' Weibring joked afterwards. 'I knew the cup was on a pretty strong slope and I was pretty cautious with the first putt. I went up and as I went to tap it in, the ball rolled back. It moved a little bit, but didn't change positions.
'What I didn't know is if I grounded the putter first. I never do that in that type of situation. I just wanted to make sure everything was right.'
Kite posted a 2-under 70 to share second place at 13-under-par 203 with Tom Jenkins, who posted a final-round 66. Mark McNulty took fourth place at 11-under-par, while Dana Quigley ended alone in fifth at minus-10. Quigley's run of 23 straight rounds at par or better was snapped Sunday as he posted a 1-over 73.
Weibring had to fight out of an early hole as Kite was hot early in the round. Kite birdied three of his first five to jump to 14 under. Weibring got within one stroke with an 18-foot birdie putt on the fifth.
The three-time winner on the Champions Tour tied Kite in the lead with a 4-foot birdie putt on the ninth. Weibring parred his next five holes as Kite fell off the pace with a pair of bogeys.
Weibring, who will turn 52-years-old on Wednesday, got to 15 under as he rolled in an 8-foot birdie try on the 15th. He parred his last three holes to claim the title.
'I played real well. I like the golf course, especially these greens, they're terrific,' Weibring said. 'I felt good coming out. I played well here last year. I played very well tee to green and rolled the ball well and just didn't make very many mistakes.'
Jenkins birdied four of his first five holes to vault to 11 under. However, he missed the green at the sixth and that led to a bogey. Around the turn, he holed out for eagle on the par-4 12th to get to minus-12. He picked up another birdie on 14th to share second.
'If I would have putted at all on Saturday, I would have won by 10 shots,' Jenkins said. 'I didn't know coming out how I would play. After my start, I thought this could be a magical day. After I holed it at No. 12, I knew I had a chance.'
Kite birdied one, two and five to move to minus-14. However, bogeys at the 10th and 13th hurt his chances at a title. He closed with a birdie at the last to end at minus-13.
