Tiger Woods went through the gears on the back nine to shoot a 67 and take a six-shot lead into the final round of the WGC Championship at The Grove.

Starting the day with a five-shot lead, Woods putted poorly early on to allow the chasing pack to within two shots.

Stewart Cink and David Howell put the pressure on, but birdies at the 12th and 15th and a brilliant eagle at the last saw Woods stay clear at 17 under.

Adam Scott was second at 13 under, with Brett Quigley and Jim Furyk in third.

Scott made an excellent 65 - the best round of the day - thanks to six birdies.

Cink's challenge petered out on the back nine as he made three bogeys to finish at 11 under, while Ian Poulter, Henrik Stenson and Howell were all on 10 under.

Woods played superbly from tee to green on the front nine, but some inconsistent putting meant the world number one's scorecard only showed pars for the first seven holes.

I just made nothing on the greens - it was very frustrating Tiger Woods

A three-putt bogey followed at the eighth for Woods, as Howell and Cink made early headway to close the gap.

But Woods showed his class as he birdied the ninth before turning on the style on the way back to the clubhouse, and ending the round with his third straight eagle at the 18th courtesy of a 30-foot putt.

Nevertheless, Woods was disappointed with his putting at The Grove on Saturday.

"I hit the ball better than in the first two rounds," said Woods.

"But I just made nothing on the greens - it was very frustrating.

"There's still some work to do and I just want to end the tournament with a win."

But Woods' title charge will start earlier than originally planned on Sunday.

The threat of thunderstorms and heavy rain on Sunday has led to organisers bringing forward the final round tee-off to 0900 BST, with the leaders starting around 90 minutes later.
