Westwood leads British Open by 2
As several contenders saw their hopes choked in the long grass, American Hunter Mahan, who famously cried when he duffed a crucial chip in the 2010 Ryder Cup, put together a joint best of the day 68 to join Woods at one-under.
"Even though I haven't won a major, I know what it takes to win one," said Westwood, who is trying to emulate fellow Briton Justin Rose, this year's U.S. Open champion.
U.S. Masters champion Adam Scott is fourth at level-par after the Australian carded a 70 and he will partner with Woods in what is shaping up to be a nailbiting shootout alongside the Firth of Forth.
Jimenez, distinctive with his frizzy hair and blue tartan trousers, was the overnight leader but a 77 left the Spaniard back in the pack at three over.
Westwood bogeyed the third but responded in magnificent fashion on the 559-yard fifth, blasting two drivers to reach the green in two and then curling in a 25-foot eagle putt to a crescendo of roars echoing across the parched course.Woods failed with a birdie attempt to leave Westwood one clear at three-under, and he stretched his lead to three when he birdied the seventh and Woods bogeyed.Just as he appeared to have taken a stranglehold, Westwood faltered and the American scented blood. At the par-four eighth, the Englishman's putter failed him as he made a bogey.
Woods pounced, flopping out exquisitely from a greenside bunker and converting his birdie chance at the same hole.
All his hard work seemed to be unravelling at the par-three 16th when his tee shot found deep rough and his hack out dribbled back down a slope while Woods prowled the green eyeing a makeable birdie putt.
Pumped-up by his escape, Westwood launched a huge drive down the 17th and Woods panicked, sending his second shot into a bunker - a terrible miscalculation that resulted in a bogey six."If I hit it flat and flush, it's fine, it carries. But I spun it. And you spin it against that wind, it's not going to go very far," Woods said of the momentum-shifting moment.Westwood sank his birdie putt to pull two clear and both parred the 18th.
Matsuyama had birdied the ninth, 10th and 11th to move to one-under but eventually slipped back to three-over.
