Justin Rose was at four-under-par on day three of the Masters at Augusta before a run of bogeys left the Englishman level with a round of 72.
After five opening pars, Rose then hit three birdies to give him a score of three-under after the back nine.
Another birdie on 14th saw the world number nine lurk around the top of the leaderboard before it all unravelled for the 31-year-old.
A bogey on 15 was then followed by a double-bogey on 16 as his promising position slipped away.
Rose dropped a further shot on the final hole to end where he started on par.
Hunter Mahan and Padraig Harrington currently hold the clubhouse lead on four-under.
