Tiger Woods looks likely to hang on to his world number one ranking despite finishing the Bridgestone Invitational at 18 over par, the worst performance of his career.
Woods finished second from bottom after firing a dismal final round 77 to finish the tournament and his chief rival, world number two Phil Mickelson, had the chance to snatch the number one ranking by finishing in the top four of the event in Ohio.
But Woods will cling on to the number one spot after the big left-hander choked on his final round with an eight-over 78 to slump into a tie for 46th.
Woods says he's not enjoying golf at the moment, while Mickelson says he's got some work to do to get his own game sharp, even though he'll eventually surpass his younger rival so long as he keeps finishing ahead of him every week.
Mickelson's looking over his shoulder too however - he says there are guys behind him in the rankings who will pass him because he's not playing well enough right now.
Unlike his fellow Americans, Hunter Mahan held his nerve to win the Invitational with a final score of 12 under.
