Justin Thomas praised the role of Jim Mackay in his US PGA triumph as the caddie’s absent former employer continued to loom large at Southern Hills.

Thomas defeated fellow American Will Zalatoris by a shot in a three-hole aggregate play-off after the pair tied on five under par and capitalised on a late implosion by Chile’s Mito Pereira, who double-bogeyed the 72nd hole.
