Rory McIlroy and Bryson DeChambeau took each other on at the Masters last month, and it was the Northern Irishman who prevailed to complete the career Grand Slam

McIlroy secured his first green jacket in a sudden-death playoff against Justin Rose, completing the modern career Grand Slam and becoming the first European to capture all four majors.

"I can only speak for myself. I can't speak for Rory. What I can say about myself is that I genuinely care about the game of golf," he said.
