The winner last year at traditional Hamilton Golf and Country Club, Furyk had a 16-under 268 total on Angus Glen's links-style North Course. He earned $900,000 for his 13th PGA Tour victory and first since last September in Ancaster.

"I really appreciate all the support I had," Furyk told the crowd during the trophy presentation on the 18th green. "It's been great coming to Canada the last two years. We'll see you next year."

Three strokes behind Singh after the third round, Furyk birdied two of the first three holes _ holing a 35-foot putt on the par-5 first and a 9-footer on the par-4 third _ before moving ahead at 13 under with his third career ace.

Furyk used a 5-iron to attack the back-right pin position on No. 4, a hole he birdied the first three days. His ball landed in the fringe just over a large bunker and rolled about 30 feet straight into the hole.

While Furyk feasted on the long par 3, Singh had three bogeys and a par on the hole, eight strokes more than Furyk. On Sunday, Singh's tee shot went 25 yards right and he dropped a shot after taking two more strokes to reach the putting surface.

Singh, the 2004 winner at Glen Abbey in a playoff with Canadian star Mike Weir, shot a 68. Ryan Palmer and George McNeill closed with 66s to tie for third at 13 under, and Bob Heintz (67) and Hunter Mahan (67) followed at 12 under.

Furyk took a two-stroke lead to the par-4 18th, but made it interesting by three-putting for a bogey. He missed a 5½-footer for par, giving Singh _ playing two groups behind _ a chance to force a playoff with a birdie.

With Furyk nervously sitting on the stairs behind the green, Singh hit his 165-yard approach shot about 20 feet over the pin. To Furyk's relief, Singh's bold putt ran 5 feet past the pin.

Furyk followed the hole-in-one with five straight pars, then holed a 5-foot birdie putt on the par-4 10th to reach 14 under and take a two-stroke lead over Mahan and Palmer. The 2003 U.S. Open champion moved three shots ahead on the par-5 11th, two-putting from 30 feet for an easy birdie.

After Mahan birdied the 11th to pull within two strokes, Furyk — after stepping away three times to further examine his line — rolled in a delicate 8-footer on the par-4 12th for his third straight birdie and a three-shot lead.

Singh and Mahan cut Furyk's lead to two, but he pulled three ahead again with an up-and-down birdie on the par-5 15th. Furyk also scrambled for key par saves on Nos. 8 and 14 _ both par 3s — and the par-4 16th after missing the greens in regulation.

With the comeback victory, Furyk became the first player to successfully defend a title in the event since Jim Ferrier won in 1950 and 1951. Sam Snead (1940-41), Leo Diegel (1924-25; 1928-29) and J. Douglas Edgar (1919-20) also accomplished the feat.
