Tiger Woods looked a beaten man after completing his third round in Ohio
Phil Mickelson could knock Tiger Woods off the world number one spot after a one-over par 71 in his third round at the WGC-Bridgestone Invitational.
Mickelson, who must finish in the top four to be in with a chance of taking the number one spot, currently lies two shots off fourth place.
Sean O'Hair and Ryan Palmer top the lead after 64 and 63 respectively.
Woods earlier hit a five-over par 75 to record his worst three-round total since turning professional in 1996.
Mickelson will take the number one spot should he manage a top-four finish and Woods fail to make the top 44.
Despite starting the day as leader, Retief Goosen fell away sharply as O'Hair powered his way to a six-under par 64, a round only bettered by Palmer's 63.
The American duo finished the day on a nine-under par 201 after three rounds, leaving open the possibility of Mickelson snatching a top-four finish - and the world number one berth.
Although Mickelson struggled to find his form all day, he managed to keep in touch with the leaders after some wayward driving, topping the leaderboard after the first nine.
But he was unable to maintain his form, bogeying two of the last four holes and making just 10 of 14 fairways.
Earlier, Woods had beaten his previous worst course total at the Firestone Country Club - recorded on Friday - by a shot, as he fell to 78th place overall after completing a round which included five bogeys.
Woods, who has held the top spot for 270 weeks, managed to hit the fairway seven out of 14 times on Saturday, but finished dismally, hitting a pair of bogeys on the final two holes.
The field in the event, which has no halfway cut, includes the top 50 players in the world.
