AKRON, Ohio (AP) - Adam Scott made four birdies over his last seven holes for a 4-under 66 on Saturday in the Bridgestone Invitational and a chance to win his first World Golf Championship.

Scott had a one-shot lead over fellow Australian Jason Day and Ryo Ishikawa, the 19-year-old from Japan who is trying to become the youngest PGA Tour winner in 100 years.

Ishikawa already has 10 wins on the Japan Golf Tour but has never been much of a factor in America. Yet he has thrilled the crowd at Firestone with a 64 in the third round, and plenty of great escapes from the trees.

Tiger Woods, in his first tournament in nearly three months, again putted poorly and shot 72. He was 13 strokes behind.
