Padraig Harrington is tied for second place - three behind leader Ian Poulter after the third round of the Honda Classic.
Harrington endured three bogeys in his first 10 holes to sky to three-over for the day but recovered with birdies at the 11th and 13th holes to end the round with a 71.
He lies on six under, the same mark as Patrick Reed, who carded a 70.
Poulter has three birdies in his front nine and added another at the 12th hole to stand at nine-under 201 for the tournament.
American Brendan Steele was alone in fourth at four-under after a 71.
England's Paul Casey (68), American Phil Mickelson (69) and Scotsman Russell Knox (70) were another shot back at three-under.
