Rory McIlroy said his final round performance wasn't good enough after he lost in a play-off for the Honda Classic.
McIlroy began the day 12-under par, two clear of the field, and improved that to 13-under with a birdie two at the fifth.
But the two-time major winner shipped six shots after that with a double bogey at 16 and a bogey at 17 leaving him a stroke behind teeing off at 18.
A brilliant second to the last gave him a shot at a winning eagle but the putt missed and he eventually lost in a four-way play-off won by American Russell Henley.
McIlroy reflected: "I didn't play well enough to deserve to win today. It's very disappointing. It was a perfect opportunity to win. No one was really coming at me.
"There's a few positives to take, but obviously it's going to be hard to get over because I had a great chance to win my first tournament of the season and I didn't.
"But yeah, 74 today wasn't good enough to get the job done. You know, even if I had of won, it would have felt a little bit undeserved in a way.
"It's tough to take at the minute but I'll sleep it off and get back at it, go down to Doral (host of this week's WGC-Cadillac Championship) and try and put myself in position to win again and see if I can do a better job."
McIlroy felt his second shot at 16 - a six-iron from a bunker which found water and led to a double bogey - was the real killer.
"I'm just thinking, play those last few holes just solid, and 16 was what really cost me.
"I was trying to hit a 6‑iron right of the target, I let the wind bring it back and I just got a little underneath it and caught it a little heavy.
"In hindsight, I probably should have hit 5‑iron and tried to hold it up because I could have got more on top of it and would have taken that fat shot out of it."
