Rory McIlroy wouldn't speak to playing partner Bryson DeChambeau during the final round Sunday at the Masters, and it turns out that was all part of his strategy. McIlroy's sports psychologist Bob Rotella claimed his silent treatment had nothing to do with DeChambeau and was more about keeping the 35-year-old focused on the task of winning the tournament.

After a birdie on his one-hole playoff against Rose, McIlroy is the sixth golfer— and first since Tiger Woods in 2000— to claim a career grand slam. The victory marked his fifth major win and first since 2014.

Australian golfer Min Woo Lee also backed McIlroy’s decision to ignore DeChambeau, adding: "When you play in two-ball pairings, you move so quick you can't talk, and plus they are in the last group. Tension. Not a big deal.”
