Rory McIlroy admitted that he let victory slip through his fingers after a final-round 74 cost him dearly at the WGC-Cadillac Championship in Florida.

McIlroy began his fourth round with a three-shot lead, but managed just one birdie in his closing 18 holes at Doral to finish in a tie for third with Englishman Danny Willett.

His inability to hold onto the lead was made all the more galling by the victorious Adam Scott's own struggles on Sunday.

Scott found the water twice in his final round as he rode his luck to secure a second successive victory and boost his confidence ahead of next month's Masters.

Understandably, McIlroy wasn't quite as buoyant: "I didn't make enough birdies. I felt like my game was okay for the most part, but I didn't take advantage of the holes I should have. I couldn't birdie any of the par fives and that's really what killed me today.

"It's frustrating because it's two out of the last three weeks. I was leading the golf tournament with 16 holes to play in Riviera, I was leading the golf tournament here going into the back nine, and to not get the job done in either two of those instances is very frustrating.

"I've got two events left to try to get that win before going to Augusta and I'm hopefully going to get it."
