Jason Day has vaulted to No.4 in the world rankings after winning the Canadian Open.
The Queenslander closed with a spectacular hat-trick of birdies, capped by a fist pump and a roar on the 72nd hole at Glen Abbey Golf Club when he made a similar putt to the one that would have sent him into The Open Championship playoff last week.
On that occasion, the 27-year-old left his birdie putt centimetres short, but he made no such mistake this morning.
"I got the ball to the hole this time which was nice," Day said with a wry grin after sinking a 7m birdie putt on the par-5 last hole.
“The first thing I said was I’ve got to get to the hole this time, that’s what I said in my head.
"There's no better feeling than coming down to the wire and contending with these guys. It was just back and forth all day, and I'm so glad that I got that putt in.
"To be able to do that it just gives me a lot more confidence going in to the rest of the season."
Day, who had been in contention for the past two majors, the US Open and The Open at St Andrews, fired a final round four-under-par 68 to finish 17 under the card to beat American Bubba Watson by a shot.
A further stroke back was hometown hope David Hearn who was aiming to become the first Canadian winner in 61 years.
It was Day's second victory on the US PGA Tour this year after he won the Farmers Insurance Open at Torrey Pines in February and showed he had quickly overcome the disappointment of St Andrews despite playing the final 36 holes of the Old Course without a bogey.
Day birdied three of his first seven holes to briefly snatch the outright lead before handing it back with dropped shots on the eighth and ninth.
He then made six pars to start the back nine before unleashing his birdie blitz.
Day is the sixth Australian to win the Canadian Open, joining Joe Kirkwood (1933), Jim Ferrier (1950, 1951), Kel Nagle (1964), Greg Norman (1984, 1992) and Nathan Green (2009).
He will now take a break before beginning preparations for next month's final major of the year, the US PGA Championship at Whistling Straits,
"I feel good, I feel really good. I'm going to take next week off," Day said.
"The last two weeks have been a big grind for me, but it's all worth it.
"All the hard work that I put into it, it's my fourth win of my career and hopefully I'll have many more.
"But right now I'm just so proud to be the Canadian Open champion."
Rising amateur Ryan Ruffels, playing on a sponsor’s invitation, didn’t make the third round cut after opening with a spectacular 66.
In his debut on the US PGA Tour, the 17-year-old dual Australian junior champion was in a tie for third after the first round before he slumped over the next two rounds and fell foul of the Tour's Rule 78 regulation.
The secondary cut stipulates that if more than 78 players remain in the field after 54 holes, those beyond that number cannot play in the final round.
