AKRON, Ohio -- William McGirt opened with a 6-under 64 for a three-shot lead in the Bridgestone Invitational as he goes for another victory in Ohio.
McGirt broke through for his first PGA Tour victory last month at the Memorial. In his World Golf Championship debut, he made six birdies and finished off his round with a 45-foot par save.
Jason Day, the No. 1 player in the world, was among those at 67.
U.S. Open champion Dustin Johnson had a U.S. Open kind of round -- 15 pars, two birdies and a bogey -- for a 69.
