Tiger Woods took another step on one of his favorite courses toward showing his game might be turning around.
Woods made six birdies Thursday to account for his mistakes and opened with a 2-under 68 at the Bridgestone Invitational. He was still four shots behind Marc Leishman of Australia, who shot 64 on a perfect day for scoring at Firestone.
Justin Rose was among five players at 65, while 27 players in the 76-man field at this World Golf Championship broke par.
It was only a first step for Woods. He opened with a 69 at the British Open two weeks ago, and then made the cut on the number.
British Open champion Rory McIlroy made a late double bogey in his round of 69.
