Nathan Green beat Retief Goosen in a playoff to secure his first PGA Tour victory in the Canadian Open.
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.
Green missed a 12-foot birdie attempt on the par-four 17th, before South African Goosen missed with an eight-foot attempt for par.

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 won 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 on 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.
