The more birdie putts Lee Westwood made, the more he began to believe he's finally fixed the biggest weakness in his game.
Westwood made 11 birdies-many on long putts-to shoot a 61 and grab a share of the lead with Louis Oosthuizen after the third round of the HSBC Champions.
Oosthuizen, meanwhile, struggled mightily on the greens and blew the five-stroke lead he had coming into the weekend. He shot a 2-under 70.
Westwood and Oosthuizen are level at 18-under going into Sunday, three shots ahead of Phil Mickelson, who made seven birdies en route to a 66.
Ernie Els briefly surged into a share of the lead on the back nine before dumping his ball into a reservoir on the tricky 15th hole and taking a double bogey. He shot a 69 to drop to fourth place, level with Bill Haas (66) and Ian Poulter (65).
Westwood, a former world No. 1, has long been considered one of the most consistent golfers in the game, yet he's never broken through to win a major, finishing runner-up twice-at the Masters and British Open in 2010.
He's also played in more World Golf Championship events than any other golfer (41), but his best result is second place on three occasions, most recently at the HSBC Champions in 2010 when he lost to Francesco Molinari by one stroke.
"It does surprise me that I've played more than anyone else. I didn't realize I was that old," the 39-year-old Englishman said. "I know I've played a lot. I've never won one."
It was the second time in three weeks that Westwood shot a 61 - he also had one to beat Charl Schwartzel in the semi-finals of the World Golf Final exhibition in Turkey in mid-October.
But as good as his score was Saturday, it wasn't even the low round of the day. That belonged to American Brandt Snedeker, who had a chance to shoot golf's magical 59 but missed a 15-foot putt for birdie on the 18th hole. He finished with a 60, a new course record.
"You don't get a chance to shoot 59 too often, maybe a couple of times in your career," he said. "I'd love to have that putt again."
Starting the day back in 12th place, Westwood began his assault on the leader board with three consecutive birdies on the first three holes Saturday.
He then birdied the fifth and seventh holes and sunk a 10-foot putt for another birdie on the 573-yard par-5 ninth hole to make the turn at 13 under, four strokes back. He kept up the pressure on the back nine, closing his round with four more birdies to catch Oosthuizen and Els.
After his third-place finish at the Masters this year, Westwood admitted that his putting was "costing me tournaments." But he said he has been working hard on his putting over the past couple months-and the results are starting to show.
"I've struggled on the greens. That's been widely and comprehensively reported," he said. "But today I felt really confident on the greens and actually looked at 20-footers thinking, 'Yeah, I'm going to make this one."'
After two rounds of nearly flawless golf, Oosthuizen was five strokes up on the field and looked to be comfortably in control going into the weekend. The South African's two-round score of 16-under 128 was the lowest through 36 holes at any World Golf Championship event since they began in 1999.
But cracks began to appear in his putting game early on Saturday. After making a nice chip shot from the bunker on the third hole, he missed a routine 5-footer for birdie-the first par-5 hole of the tournament he's failed to make birdie or better.
Oosthuizen then three-putted on the par-3 fifth hole for bogey-just his second bogey of the tournament-and let another birdie chance slip away on the sixth when his 25-foot putt stopped short of the hole by inches. He narrowly missed two more birdie putts within 10 feet on the eighth and ninth holes, settling for par on both.
"Early I didn't play really well and then started to find a little bit of form on the back nine, but just didn't make any putts," Oosthuizen said. "The putter went cold on me today."
While Oosthuizen was missing his putts, Els was sinking his: a 7-foot birdie putt on the fourth, a 3-foot shot for eagle on the par-5 seventh and another 3-footer for birdie on the ninth to pull within one stroke at the turn.
Els' solid round came undone, however, on the 580-yard, par-5 15th hole, which presents golfers with two paths to the hole: a safe route down the length of the curving fairway or a riskier, 250-yard jump over a reservoir straight to the green.
Els took the latter option and paid the price, plunging his second shot into the water. He managed to clear it with his next shot, but then missed an easy 5-footer on the green. He had been bogey-free up to that point in the tournament.
After his remarkable 12-under performance, Snedeker moved up from a tie for 38th place to seventh going into the final day, one shot behind Els. The young Indian star Gaganjeet Bhullar, ranked 108th in the world, also had a surprisingly strong round, birdying nine times for a 63. He jumped from 27th place to a tie for eighth.
