MIAMI (AFP) — World No. 1 Scottie Scheffler cruised to a five-stroke victory on Sunday at the PGA Arnold Palmer Invitational to capture his first tour victory in nearly a year.

Scheffler, the 2022 Masters champion, fired a bogey-free six-under par 66 to finish 72 holes on 15-under 273 at Bay Hill in Orlando, Florida.

That was enough to defeat reigning US Open champion Wyndham Clark, the runner-up on 278 after a closing 70, with Ireland's Shane Lowry, the 2019 British Open champion, third on 279 after a closing 72.

"I played a good round of golf," Scheffler said. "Got off to a good start and just did my best to keep things rolling."

"As we made the turn on the back nine, I knew I had a few shots lead. I didn't look at many leaderboards. I stayed in my own little space and just tried to keep pushing."

Scheffler matched the low round of the week and the 27-year-old American became the first reigning world number one to win at Bay Hill since Tiger Woods in 2009.

"Hat's off to Scottie," Clark said. "He's the best player in the world right now and that's what the best players in the world do, they shoot 66 in a final round."

It was Scheffler's seventh career PGA Tour triumph and his first since last year's Players Championship — a title he will try to defend next week.

"It would be borderline unfair if he starts putting really good," Clark said. "If he starts putting positive each week he's going to be really hard to beat."

"Scottie should win almost every year here. With his ball striking, this golf course is so demanding tee to green and he's been the best last few years in that category, so I'm not shocked."

Through the past 12 months, Scheffler said he wasn't frustrated by his win drought.

"Just stuck with my process," he said. "Had a good couple off weeks with friends at home to kind of reset. Going into this week I tried to have a good attitude."
