Top-ranked Scottie Scheffler captured his first major title on Sunday by winning the Masters in dominating fashion, holding firm down the stretch to seize the green jacket after Tiger Woods completed his comeback from severe leg injuries.

Scheffler fired a final-round one-under-par 71 to finish 72 holes on 10-under 278 and defeat four-time major winner Rory McIlroy by three strokes with Australian Cameron Smith and Ireland's Shane Lowry sharing third on 283.

"It was a long day, a tough day for me," Scheffler said. "I just tried to keep my head down and execute my shots."

Scheffler, who only won his first PGA title in February, holed a spectacular chip-in birdie from 87 feet at the par-4 third to blunt an early charge by Smith, last month's Players Championship winner.

"It was not a shot I expected to see go in but it got things off and rolling for me," Scheffler said.

He also birdied the 14th and sank a 14-foot birdie putt at the par-5 15th to signal there would be no collapse to open a door for McIlroy, chasing an Augusta National win to complete a career Grand Slam.

Scheffler endured an agonizing double bogey at the 18th hole, needing three putts from inside 5 feet before finally sinking the putt to secure his breakthrough major triumph.

"I didn't want to break my concentration," Scheffler said. "The minute I did was on 18 green when I finally got on there and I had a five-shot lead and was like, 'All right, now I can enjoy this.' And you saw the results of that."

The 25-year-old American took a $2.7-million top prize from a $15-million purse and joined 1991 Masters champion Ian Woosnam as the only players to win majors in their debut events as world No. 1.

Scheffler is only the fifth player to win the Masters while atop the rankings, joining Welshman Woosnam and Americans Fred Couples, Dustin Johnson and Tiger Woods, whose epic injury fightback dominated attention all week.

Spectators gave Woods a standing ovation at the 18th green for his astonishing return to golf 14 months after a car crash that left him hospitalized for weeks and unable to walk for months.

"I wasn't playing my best but to have their support out there, I don't think words can describe it," Woods said.

The 15-time major winner fired weekend 78s, his worst Masters rounds, to finish with his highest Augusta National 72-hole score of 301 and in a worst-ever 47th place.

But the fact Woods was able to walk the course and play at all was nothing short of incredible given the 46-year-old medical marvel had not played a top event for 17 months and feared amputation of a right leg now held together with rods, plates, pins and screws.

"It has been a tough road and one that I'm very thankful to have the opportunity to be able to grind through," Woods said.
