Golf fans, check this out—Rory McIlroy just revealed an insane piece of memorabilia from his caddie, Harry Diamond: an Augusta National scorecard signed by the five other Grand Slam winners—Sarazen, Hogan, Player, Nicklaus, and Tiger! Rory joked about not signing it himself yet, and threw a playful jab at Scottie Scheffler possibly joining the club. This is the kind of gift that cements the bond between player and caddie, and stirs up Grand Slam rivalry talk! #Sports #Golf #RoryMcIlroy
