Chez Reavie overcame an early wobble to card a final round 70 and clinch his maiden PGA Tour title with a three-shot victory at the Canadian Open on Sunday.
Reavie, who had had just one top-30 finish in 21 starts during a tough rookie season, began the final round with a one-shot lead over compatriot Anthony Kim.
He bogeyed two of his three opening holes but grimly fought back to seal victory with a birdie at the last for a 17-under 267 winning total.
Journeyman Billy Mayfair, bidding for his first PGA Tour win in a decade, started the day five behind the leader and had cut the deficit to two with two to play.
But he could get no closer, signing for a three-under 68 to finish alone in second on 14 under.
Sean O'Hair (68) and Steve Marino (70) were one shot further adrift on 271.
Kim, chasing his third PGA title of the season, stayed in contention until a back-nine collapse with bogeys at 11, 17 and 18 dropped him back to 11 under.
"I didn't feel comfortable until I hit my third shot on the green on 18," Reavie told reporters. "That's when I relaxed and said, okay, I've got it."
Local hope Mike Weir, bidding to become the first Canadian in 54 years to lift the national title, finished in a tie for fifth but ignited the home crowd with a late charge including birdies on two of his three final holes.
