Tiger Woods made a torrid start to his third round at the Hero World Challenge as Charley Hoffman's lead was reduced to just a shot.
Woods was five shots adrift of Hoffman at the halfway mark and declared he was "still in it" in his first competitive tournament for 10 months after recovering from a fourth back operation.
The 14-time major champion's challenge faded on Saturday, though, as he endured an almighty struggle with the wind up on the front nine to slip back, hitting the turn in 40 to drop to three under.
Woods went out in 31 in his second round, but four bogeys and not a single birdie saw him plummet down the leaderboard with nine holes to play on quickening greens at the Albany Golf Course.
The 41-year-old tournament host led for a short time following a magnificent start to his second round, but it was a very different story on moving day as he bogeyed the first after pulling his tee shot left.
Woods overcooked his approach at the third and failed to hole a par putt following a poor chip, going on to drop further shots at six and seven as he failed to find his rhythm.
Hoffman was level par through eight on 12 under, leading Tommy Fleetwood by just one shot. Justin Rose and Jordan Spieth were another two strokes back.
