Lee Westwood will take a two-shot lead into the final round of the 142nd Open Championship after a rollercoaster third day at Muirfield.
That means Tiger Woods will have to make history to win his 15th major title and deny the Englishman a first at the 62nd attempt after failing to keep pace with his playing partner on a dramatic afternoon.
Westwood carded an eagle and three birdies in a round of 70 that left him atop the leaderboard on three under par, with Woods (72) and fellow American Hunter Mahan (68) the only other players in red figures on one under.
"I know what to expect tomorrow," Westwood said. "I know what to do, I know what it takes.
"It's just a case of believing you are good enough to win. When you analyse it, you don't want to say it, but tomorrow is just another 18 holes. I'm playing well and putting well and there's no reason why I can't carry on.
