Rory McIlroy ended a 16-month winless run on the PGA Tour with a thrilling come from behind triumph at the Deutsche Bank Championship.
McIlroy, 27, was four over after his first three holes in the championship, but rallied to claim the two-shot victory over Englishman Paul Casey.
Starting six strokes off the pace on the final day at TPC Boston, the Northern Irishman landed seven birdies to shoot a stunning 65, and landed his 12th PGA Tour title.
“It’s amazing to think how I started this tournament and what was going through my mind after the first three holes. Then all of a sudden, here I am standing with the trophy four days later. It's pretty cool,” McIlroy said.
His latest win came a week after the world number three changed to a new putting coach, and followed a tweak to his putting grip.
"I played some great golf and holed some great putts. I'm just really proud of myself, how I hung in there on the first day and then got some momentum on Saturday. Then I just went with it,” said McIlroy.
"It's nice to get that first win in the States this year and hopefully I can take this momentum into the next couple of weeks and ultimately the Ryder Cup."
McIlroy led the field in distance off the tee with an average of 312.9 yards, and strokes gained at 12.249.
The four-time major champion last won at the Irish Open in May.
