(Reuters) -Rory McIlroy's breakthrough Masters win was shaped by a deliberate strategy to stay laser-focused, even if that meant not saying a word to playing partner Bryson DeChambeau during the final round, McIlroy's sports psychologist Bob Rotella said on Tuesday.
Northern Irishman McIlroy ended his long wait for a Masters title with a birdie on the opening hole of a sudden-death playoff to beat England's Justin Rose at Augusta on Sunday.
