AUGUSTA, Georgia — Rory McIlroy turned another major collapse into his grandest moment of all, hitting a wedge into 3 feet for birdie in a sudden-death playoff Sunday to finally win the Masters and take his place in golf history as the sixth player to claim the career Grand Slam.

What should have been a coronation for McIlroy along the back nine at Augusta National turned into a heart-racing, lead-changing jaw-dropping finish at golf’s greatest theater that ended with McIlroy on his knees sobbing with joy and disbelief.

“I started to wonder if it would ever be my time,” McIlroy said in Butler Cabin before Scottie Scheffler helped him into the green jacket.

It ended with more heartache for Justin Rose, who lost to Sergio Garcia in a playoff in 2017 and forced this one with a clutch 20-foot birdie on the 18th hole for a 6-under 66. He wound up joining Ben Hogan as the only players to lose twice in playoffs at Augusta National.

McIlroy lost a two-shot lead in two holes at the start. He lost a four-shot lead on the back nine in a matter of three holes with shocking misses, one of them a wedge into the tributary of Rae’s Creek on the par-5 13th.

And right when it looked as though he would blow another major, McIlroy delivered two majestic shots when nothing less would do, two birdies that sent him to the 18th hole with a one-shot lead. That still wasn’t enough. He missed a 5-foot par putt for a 1-over 73 and the first Masters playoff in eight years.

McIlroy’s wedge bounced onto the slope of the top shelf with enough spin to trickle down to 3 feet. And when Rose missed from 15 feet, McIlroy finally sealed it.

McIlroy went 11 long years without a major, knowing the Masters green jacket was all that kept him from joining Tiger Woods, Jack Nicklaus, Gary Player, Ben Hogan and Gene Sarazen as the only winners of golf’s four professional majors.

He raised both arms and let the putter fall behind him, and before long he was on his knees, then his forehead on the 18th green as his chest heaved with emotion.

So ended one of the wildest Sundays at a major that is known for them. U.S. Open champion Bryson DeChambeau, who beat McIlroy at Pinehurst No. 2 last June, had the lead after two holes when McIlroy opened with a double bogey.

He crashed out with a pair of three-putts and two shots into the water on the back nine, closing with a 75.

Ludvig Aberg, a runner-up in his Masters debut a year ago, suddenly had a share of the lead when McIlroy fell apart on the middle of the back nine. He missed a birdie putt from the fringe to take the lead, then finished bogey-triple bogey.

Rose had every reason to believe he threw away his chances on Saturday with a 75 that put him seven shots behind, and then two bogeys on the front nine. Even as he steadied himself, he was four shots back and running out of time. He did his part in a 10-birdie round and that dynamic birdie putt to cap it off.

McIlroy helped in a big way.

Nothing was more shocking than the 13th. McIlroy played it safe, leaving himself a big target and a lob wedge. He missed his mark by some 20 yards, the ball disappearing into the tributary of Rae’s Creek and leading to double bogey.

Then came a tee shot into the pine straw that led to another bogey, and the lead was gone again. But he was resilient as ever – he’s been like that his entire career. Seemingly in trouble left of the 15th fairway, McIlroy hit 7-iron around the trees and onto the green to 6 feet.

He missed the eagle putt – the birdie still helped him regain a share of the lead. Two holes later, facing a semi-blind shot, he drilled 8-iron and chased after it, urging it to “Go! Go! Go! Go!” And it did, barely clearing the bunker and rolling out to 2 feet for birdie and a one-shot lead.

Turns out that wasn’t enough either. He hit into a bunker from the fairway. He missed the 5-foot putt for the win. There was more work to do. But the 35-year-old from Northern Ireland never wavered in what he came to Augusta National to do.

He leaves with a green jacket.
