Rory McIlroy picked up his first victory since September 2016 as he won the Arnold Palmer Invitational.
The 28-year-old carded an eight-under-par 64 to finish on 18 under, three ahead of Bryson DeChambeau at Bay Hill.
England’s Justin Rose finished third on 14-under after he closed out with 67, four behind McIlroy.
Tiger Woods, an eight-time winner of the event, finished tied for fifth on 10-under-par after closing out the day with 69 to end eight shots back.
McIlroy, a four-time major winner, began final round two shots adrift of Swedish overnight leader Henrik Stenson, but his bogey-free 64 was the lowest score of the day.
He opened his final round with five pars before making three birdies in the next four holes to turn at halfway in three under.
Three pars followed on the back nine before a crucial spell saw him birdie five of the last six holes including the par-four 18th.
DeChambeau, whose sole PGA Tour win came at the 2017 John Deere Classic, made an eagle on the par-five 16th to take him to within one of McIlroy.
But the Northern Irishman’s three on the final hole sealed his first win at Bay Hill as the American three-putted to bogey and finish three shots back.
Olympic champion Rose finished one ahead of Rio silver medallist Stenson.
McIlroy, who was outside of the world’s top 10 prior to this victory, will compete at next week’s World Golf Championship Match Play event at the Austin Country Club in Texas before heading to Augusta for the Masters the week after.
