Golf: Justin Thomas wins Bridgestone Invitational by four strokes

Justin Thomas took all the drama out of the final World Golf Championship at Firestone, never letting anyone closer than two shots and closing with a 1-under 69 to win the Bridgestone Invitational for his third PGA Tour title this season. Playing in the final group with Rory McIlroy, the 25-year-old Thomas made only two birdies. That was all he needed on a day when just about everyone within range was making all the mistakes. McIlroy finished the back nine with consecutive bogeys and never recovered. Ian Poulter shot 74. Jason Day tried to make a run by making three straight birdies, only to play the final six holes in 5 over to shoot 73.
