Justin Rose and Bill Haas finished the day tied at the top of the leaderboard following the second round of the Arnold Palmer Invitational.
Rose had led at the end of the first round but dropped two shots in Orlando on Friday en route to a second-round 70 - in contrast to Haas, who produced an impressive 66. The pair were one ahead of John Huh.
Defending champion Tiger Woods had looked to be challenging for a top spot but gusty winds down the back nine scuppered his bid, with three bogeys in the final three holes.
Today was also notable for Phil Mickelson's failure to make the cut, the four-time major winner producing an error-strewn 79 including two triple-bogeys.
So too Brandt Snedeker, whose final two holes - and the end of his tournament - were marked with a double and triple bogey.
Rose had shot a 65 in the opening round to end the day two ahead of Huh with John Rollins and Brad Fritsch a further stroke adrift.
Today Rose enjoyed a good start, picking up four shots to head the leaderboard but bogeys at the 14th and 18th pegged him back.
Haas, though, enjoyed a flawless round with an eagle on the par-five 16th as well as four birdies for a 66.
Huh collected birdies on the fifth and seventh holes and, although he dropped a shot on the 11th, he picked up two more on the final three holes to finish with a 69.
Woods initially made an ideal return to the course today with a birdie at the first and an eagle at the sixth.
He picked up two further shots at the 11th and 13th, but his hopes of a clean round went with those three straight closing bogeys to finish the day in a three-way tie for seventh.
That was one adrift of Ken Duke, Jimmy Walker and JJ Henry who were tied for third.
Woods said: "I played way better than what I scored today.
"I missed a couple of short ones, and I had a rough finish.
"The good news is we've got 36 holes to go.
"I've sort of made my share of mistakes on the last few holes the last couple days, and I need to clean that up."
