OAKVILLE, Ontario — The Small Unit came up big in the Canadian Open.

Chez Reavie, proudly sporting an Arizona Diamondbacks logo on his light blue shirt, won the national championship yesterday for his first PGA Tour title, closing with a 1-under 70 in near-perfect conditions for a three-stroke victory over Billy Mayfair.

"Oh, man. I'm just so excited," Reavie said. "I don't think a lot of people understand when you're growing up and you're practicing and you're working so hard, this is, obviously, your goal. But there are no guarantees."

At a generously listed 5 feet 9, the 26-year-old former Arizona State player picked up the Small Unit moniker in a joking reference to Randy Johnson, the 6-foot-10 Diamondbacks pitcher known as the Big Unit.

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

"It was crucial to hit fairways so you could lift and clean your ball and place it in a good lie, especially when you don't hit it as far as some of the other guys do," Reavie said. "So, it really played into my hands.

Playing for the sixth straight week, Reavie finished at 17-under 267. He earned $900,000 and spots in the World Golf Championships-Bridgestone Invitational and PGA Championship the next two weeks along with the 2009 Masters.

After entering the week with career earnings of $746,414 in 27 PGA Tour starts and 52 Nationwide Tour events, he was amazed when told that he had made $900,000.

"How much? $900,000. That's unbelievable, really," the PGA Tour rookie said. "Yeah, wow! That's all I can say is wow to that."

Mayfair, also a former Arizona State player, shot a 68.

Sean O'Hair (68) and Steve Marino (70) were 13 under, and Canadian star Mike Weir (69) was another stroke back along with Nicholas Thompson (69) and Scott McCarron (71).

Honolulu's Parker McLachlin closed with a 73 to finish at 279. He earned $29,714.

EVIAN MASTERS

EVIAN-LES-BAINS, France — Helen Alfredsson won her first LPGA Tour title in five years yesterday, defeating rookie Na Yeon Choi in a playoff at the Evian Masters. The 43-year-old Swede made a 3-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

TROON, Scotland — Bruce Vaughan won the Senior British Open yesterday for his first career victory, sinking a 20-foot putt to beat John Cook on the first playoff hole. Cook squandered a three-stroke lead after 10 holes at Royal Troon but still went to the 72nd leading Vaughan by one. Cook sent his tee shot right into the rough and then played his third shot well short of the green. He decided to putt, but left it 15 feet short for a bogey to finish with an even-par 71 and a 6-under 278 total. Vaughan made a par for a 70 that forced the Americans back to No. 18 to begin the playoff.
