Tiger Woods stumbled to a career-worst round of 85 in the third round of the Memorial Tournament in Ohio on Saturday.

Woods, whose previous worst of 82 came at the Waste Management Phoenix Open in January, struggled throughout and was already nine over par before finishing with a quadruple-bogey on the par-four 18th.

Bogeys on the fourth and fifth holes and double-bogeys on the eighth and ninth saw the 14-time major winner make the turn already six over par, but things would only get worse.

The 39-year-old bogeyed the 11th, 12th and 14th holes before taking a shot back on the par-five 15th.

Woods then dropped a further stroke on the 17th before it all went wrong on the 18th.

He sent his tee shot into a water hazard, then found further trouble as he hit a bunker before finally making the green in five shots.

But his problems were not over as he three-putted before making a swift exit, declining to speak as he went.

Woods, who has insisted he is feeling better after recent back problems, had already had his struggles this week, opening his first round with three bogeys in the first four holes and a double-bogey on the 18th, but made the cut with a round of 70 on Friday.
