The putt broke a tie with David Toms and Chad Campbell. Jay and his son, Bill Haas, shot a 9-under 62 and finished with a two-round total of 20-under 122, worth $250,000 of the $1.3 million purse.
They finished three strokes off the tournament record of 119 set by the teams of Mark Calcavecchia and Nick Price and Brad Faxon and Gary Player in 2001.
Toms and Campbell shot an 8-under 63, finishing 19 under. Campbell rolled in a 5-foot birdie putt on 17 that tied the teams at 19 under.
Toms missed a 20-foot birdie from the fringe on 18 and Campbell pushed a 25-foot birdie putt to the right.
That left the door open for Jay Haas, who has nine PGA Tour victories to his credit. His approach shot on 18 landed above the hole while Bill Haas left his shot 10 feet to the right.
'I felt like (Bill) was going to end up putting,' Jay Haas said. 'I was almost resigned to the fact it was going to be him making the putt. But I hit it and looked up and it was kind of on a good line. It kept tracking and with about 3 feet to go, I felt like I made it. I don't think either one of us was too disappointed.'
Jay Haas was anything but disappointed in how his son, a May graduate of Wake Forest playing in his second pro tournament, did on the front nine.
Bill Haas eagled the par-4, 311-yard sixth hole and then shot a birdie on the par-4, 462-yard seventh.
'We were kind of struggling a little bit, (we were) even through five,' Jay Haas said. 'We had just bogied No. 5. So, the putt that (Bill) made for eagle was huge for us. He made about a 25-foot putt.'
Playing with his son for the first time as a pro made the tournament, let alone the victory, even more special.
'Being paired with him and having him play in the event with these other great players is victory enough for me, personally,' Jay Haas said. 'I feel extremely, extremely lucky to have him here. To win the tournament was icing on the cake.'
The team of Champions Tour veteran Dana Quigley and his nephew, Brett, shot 10-under 61 that was the day's low score.
