Hideki Matsuyama storms to victory at Bridgestone Invitational as Rory McIlroy falls away

Hideki Matsuyama stormed to a remarkable sixth victory in his last 20 events as Rory McIlroy's bid for a second WGC-Bridgestone Invitational title petered out in Akron.

Matsuyama fired an eagle and seven birdies in a brilliant closing 61 at Firestone Country Club to finish 16 under par, five shots ahead of two-time major winner Zach Johnson, with Charley Hoffman a shot further back in third.
