Bob Tway left it late before coming through to beat Brad Faxon in a play-off at the Canadian Open in Hamilton.
Tway became the eighth player of over 40 to win on the tour this year
The 44-year-old won with a bogey at the third extra hole after a round of 66 left him tied on eight under with Faxon.
"It's a really special win," said Tway. "I've been coming to Canada for a lot of years.
"This is a national open and it means a lot. I've always thought of it as a little bit bigger tournament than a normal stop."
Tway sank a 25-foot birdie putt on the 18th to tie Faxon on eight under par and force the play-off.
Faxon then let a golden opportunity pass on the second extra hole when he missed a four-foot birdie putt for the championship, following a superb 50-foot bunker shot.

Tway took advantage at the next when a wayward drive on 18 left Faxon with a double bogey.
"My hat's off to Bob, he played well," said Faxon.
"That 18th hole is tough. You have to get it on the green and it isn't easy to do."
Tom Pernice Jr. closed with a bogey for a 68 to finish a stroke out of the play-off, with Japan's Hidemichi Tanaka in a tie for fourth with South Korea's KJ Choi on six under.
Masters champion Mike Weir shot a 69 to finish 10th on three under.
