Billy Horschel claimed a share of the lead going into the final round of the Arnold Palmer Invitational by sinking a 28-foot birdie on the 18th hole.
Horschel is tied on seven under with fellow American Talor Gooch after a one-under 71 on day three at Bay Hill.
“To make that putt on 18 to shoot one under par on a really tough day is really satisfying,” said Horschel.
The Northern Ireland duo of Rory McIlroy and Graeme McDowell are four shots off the lead.
McIlroy struggled to a 76, with his final four holes featuring a double bogey, two bogeys and a birdie.
McDowell fared much better with a 69, sinking four birdies on a blemish-free back nine.
In gusty conditions and on slick greens, Horschel carded four birdies while Gooch missed a five-and-a-half-foot putt for par on the 18th to shoot 72.
Overnight leader Viktor Hovland is one back after a 75 that featured six bogeys, with the high point an eagle on the sixth hole.
