OAKVILLE, Ontario — Chez Reavie won the Canadian Open on Sunday for his first PGA Tour title, closing with a 1-under 70 in near-perfect conditions for a three-stroke victory over Billy Mayfair.

The short-hitter was on the mark all week at rain-softened Glen Abbey, hitting 44 of 56 fairways in regulation and 54 of 72 greens. The accurate play was a big factor, with the players allowed to use preferred lies in the fairways all four days.

Playing his sixth straight week on the tour, Reavie finished at 17-under 267. He earned $900,000 and spots the next two weeks in the World Golf Championships-Bridgestone Invitational and PGA Championship.

Mayfair shot a 68. Sean O'Hair (68) and Steve Marino (70) tied for third at 13 under, and Canadian star Mike Weir of Draper (69) was another stroke back along with Nicholas Thompson (69) and Scott McCarron (71).

Anthony Kim, a two-time winner this year coming off a seventh-place tie in the British Open, began the round a stroke back, but followed his third-round 64 with a 75 to tie for eighth at 11 under. The 23-year-old American would have moved into the top 10 in the world rankings with a victory.

LPGA TOUR: At Evian-Les-Bains, France, Helen Alfredsson won her first LPGA Tour title in five years, defeating rookie Na Yeon Choi in a playoff. The 43-year-old Swede made a three-foot birdie in the third round of the playoff at the par-5 18th, while the 20-year-old Choi, of South Korea, parred the hole. Alfredsson had a 67 in the final round, Choi shot a 66 and overnight leader Angela Park closed with a 71 as all finished at 15-under 273. The 19-year-old Park was eliminated in the first round of the playoff at No. 18 when her birdie attempt rolled around the lip of the cup and stayed out.

SENIOR BRITISH OPEN: At Troon, Scotland, Bruce Vaughan won on the first playoff hole, sinking a 20-foot putt to beat John Cook. Cook squandered a three-stroke lead after 10 holes Sunday and went to the 72nd still leading Vaughan by a shot. But Cook sent his tee shot into the rough and had a bogey-5 to finish with an even-par 71 and a total of 6-under 278. They began the playoff at No. 18, where Vaughan holed his putt and Cook missed from 12 feet to end it. Eduardo Romero, who was third, failed to make the playoff after missing an 8-foot putt at the last for a bogey.
