Nathan Green won the Canadian Open on Monday for his first PGA Tour victory, beating Retief Goosen with a par on the second hole of a playoff in the rain-delayed tournament. After Green missed a 12-foot birdie attempt on the par-4 17th, Goosen's 8-foot par try slid right, ending the first Monday finish in the national championship since 1988. “It's a huge surprise to finally win,” said Green, the 34-year-old former Canadian Tour player from Toronto – Toronto, Australia, that is. “This is where I started my pro career. I love coming up here. The people are great.” In sunny conditions, Green completed a third-round 69 with an eagle on 18 and shot a 68 in the fourth round at saturated Glen Abbey. 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 18 on the first extra hole, but missed a 6-foot birdie try after leaving his bunker shot above the hole. Anthony Kim (66-73) and Jason Dufner (70-73) tied for third, four strokes back at 14 under in the event soaked by nearly 5 inches of rain the first four days. Lee Janzen (70-67), Brandt Snedeker (67-68) and Jerry Kelly (72-71) followed at 14 under. Stephen Ames was the top Canadian, tying for eighth at 12 under after rounds of 72 and 67. Mike Weir (69-71) tied for 24th at 10 under. Green won for the second time in Canada, following a 2000 victory in a Canadian Tour event in Sudbury. He also won the Queensland PGA in Australia in 2000, and took the European tour's 2006 New Zealand Open.
