PALM HARBOR, Florida - Adam Hadwin is skipping his first World Golf Championship and asking for a refund for his honeymoon to Tahiti.

He couldn't be happier.

Seven weeks after he shot a 59, and two weeks before his wedding, Hadwin added another eventful chapter to his amazing year.

He threw away a two-shot lead with three holes to play by hitting a tee shot into the water, kept his wits and then closed with two pars for an even-par 71 to win the Valspar Championship by one shot over Patrick Cantlay for his first PGA Tour title on Sunday.

"You're never quite sure when you're going to get the job done," Hadwin said.

"I just went there today and stuck to what I do best, just hit some quality shots and really made the game super easy outside of hole No 16.

"I feel a little fortunate after that hole to be sitting here, but I'll certainly take it, and I can't wait for everything that comes with this win."

The victory moves him to No 51 in the world and makes him eligible for the Dell Match Play - except that he's getting married that week.

It also sends the 29-year-old Canadian to the Masters, meaning he will have to postpone that honeymoon to French Polynesia. Instead, he'll be preparing for Augusta National, the place he called the "greenest place on earth".

Even with a four-shot lead going into the final round, all Hadwin wanted was a chance over the final few holes.

The trick was reminding himself he was right where he wanted to be.

Hadwin twice holed big birdie putts on the back nine at Innisbrook as Cantlay was in close for birdies of his own, a 25-footer on the par-5 11th and then a 55-footer on the par-3 13th to keep a two-shot lead.

But it all changed on the 16th, the start of a tough three-hole finish at the Copperhead Course.

Hadwin's 3-wood peeled off to the right and never had a chance, and he walked off the hole with a double bogey and a tie for the lead.

From the 18th fairway, Cantlay blinked first.

The former No 1 amateur in the world, playing for only the second time after missing two years with a back injury, leaked his approach into a bunker. Hadwin's approach went just over the back against the collar of the fringe, leaving him a belly wedge down the grain that came off perfectly and settled two feet below the cup.

Cantlay's bunker shot was short, and he missed the 15-footer to force a playoff.

He saved just one of six from the sand over the week.

The consolation prize for Cantlay was a runner-up finish that paid $680,400 - more than enough for him to secure full status for the rest of the year.

"It doesn't really feel like much consolation at the moment," Cantlay said. "I didn't finish the deal."

Even in loss, it was a bright return for the UCLA star. Cantlay wondered if his back would ever allow him to regain his form.

While still in college, he shot 60 at the Travelers Championship in 2011, was low amateur in the US Open and didn't finish out of the top 25 in his four PGA Tour starts.
