Nathan Green beat Retief Goosen in a play-off to win the rain-delayed RBC Canadian Open and land his first PGA Tour victory. A par on the second hole at at the Abbey Golf Club at Oakville proved decisive in the first Monday finish in the event since 1988.

Australia’s Green missed a 12-foot birdie attempt on the par-four 17th, before South Africa’s Goosen missed with an eight-foot attempt for par.

Earlier, Green completed a third-round 69 with an eagle on the 18th hole and shot a 68 in the fourth round, while Goosen three-putted the 18th for par and a 67 in the morning, then eagled it in the afternoon for a 69.

Goosen had a putt to win on the 18th — the first extra hole — but missed a six-foot putt for birdie after leaving his bunker shot above the hole

Green, who took the European Tour’s New Zealand Open in 2006, told www.pgatour.com: “It’s a huge surprise to finally win. This is where I started my professional career.”

Anthony Kim and overnight leader Jason Dufner were tied for third after one over par final rounds of 73, four strokes back at 14 under in an event marred by nearly five inches of rain the first four days.

Lee Janzen finished with a 67 for a share of fifth, one shot further back, alongside Brandt Snedeker and Jerry Kelly.

Scotland’s Martin Laird had a good final round, with a seven under par 65 seeing him finish seven shots off the pace, while England’s Luke Donald — who finished tied fifth at the Open last weekend — was a stroke further back on 278 after a final round 71.
