After halving the first hole with pars, Gamez sent his second shot at the second hole, a par five, into the water, while Couples' approach was just six feet away. Two putts later, Couples had his first win of the year.
Couples had shot 32 on the front nine yesterday, the tournament having been reduced to three rounds after Saturday's play was abandoned because of the bad Florida weather. He had his fifth birdie of the day on the 10th. At the 12th he was 12 under, with a four- shot lead over Larry Mize. Two players were at eight under - Robert Gamez and Dick Mast. But Couples missed a three-foot birdie putt on 13, and then missed the green on 14 and dropped another shot, and his lead was down to one shot. Then Gamez edged his way past Mize and caught Couples.
Nick Faldo finished tied for 16th after an even par round of 72. Faldo played the front nine extremely well tee to green, missing no fairways or greens, but had just one good putt, a 25-footer for a birdie on the fourth hole.
Faldo said: 'I'm swinging really well. It's just the same old thing with the putter.'
Instead of staying on for the Bay Hill tournament as he had planned to, Faldo left America last night, and will return in three week in New Orleans after the birth of his third child.
