AKRON, Ohio (AP) 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.
The surprise was Jordan Spieth, who putted for birdie (and missed) only one time in 10 holes. He hung in there with several big par putts, closed with four birdies and shot 68.
