AKRON, Ohio — Phil Mickelson and Vijay Singh slugged it out in the trees and on the greens today throughout an up-and-down day at the Bridgestone Invitational until they wound up in a tie for the lead with a far more conventional Lee Westwood.

Mickelson went six straight holes without hitting a fairway, then poured it on late with three straight birdies until he finished with a bogey from the fairway for a 2-under 68.

Singh twice missed par putts from inside 3½ feet, but chipped in from a scary lie above the third hole and managed a 69. Westwood drove the ball as well as he ever has and made long putts for birdie and par on his way to a 67.

They all were at 8-under 202 and gave this World Golf Championship a truly global feel — three players from three parts of the world, each seeking his first WGC title.

One shot behind was Stuart Appleby of Australia, the only player to compete in all 29 of these events since they began 10 years ago.

"You want to win everywhere, don't you?" Westwood asked. "I'm proud that I've won on every tour, basically. I haven't won a World Golf Championship, so it would mean a lot, and obviously give me a massive amount of confidence going into the next week."

Mickelson won at Firestone a dozen years ago before it was a WGC event, and this might be his best chance at a world title. After straightening out his tee shots, he closed out his string of birdies by going for the green on the 620-yard 16th hole, hitting a hybrid into the back bunker and getting up and down.

But he lost the outright lead on the final hole, coming up well short of the green and failing to save par from 8 feet.

On a Firestone South course that was slowly starting to dry, the third round separated what had been a jammed leaderboard. Even so, 10 players were separated by four shots going into the final round, a group that included Darren Clarke, who had a 65 and was four behind as he tries to win a third WGC title.
