"I've seen him play the best golf of his life probably in Pebble Beach in 2000 and I know what he's capable of doing."
Woods had looked decidely shakey on Thursday at the start of the storm-interupted Masters but he insisted Saturday night he was not playing badly, but simply not getting the breaks.
"I kept hitting good golf shots, just nothing happened, I would just mess it up or I's get a bad break. So just keep hanging in there, keep hitting quality golf shots and it will turn, and luckily it turned," said Woods.
Jack Nicklaus, who played his final Masters round on Saturday, said Woods was still by far the best player in the world.
"He's still obviously the dominant player. He has got so much talent. Like anybody who has dominated the game, maybe myself, Tiger doesn't have to play his best to win.
"But when he plays his best, he's going to probably win," said Nicklaus.
If Woods wins his fourth green jacket on Sunday it will take him to nine major titles and halfway to his target of equalling Nicklaus' 18 majors.
