McIlroy: History makes Grand Slam difficult

-- Rory McIlroy's awareness concerning golf's career Grand Slam is quite keen, as was made clear Wednesday when he interrupted a question about it to clarify that he already has had four chances to get the job done.McIlroy, who turns 30 this year, has been on hold since winning the 2014 Open at Royal Liverpool, needing the Masters to join Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus and Tiger Woods as the only players to win all four major championships.He gets a fifth opportunity next month at the Masters, where he has been in the top 10 in each of the past four years since winning his fourth major title at the 2014 PGA Championship."It's definitely taken me time to come to terms with the things I've needed to deal with inside my own head, and I think sometimes I'm too much a fan of the game because I know exactly who has won the Grand Slam and I know exactly the people I would be putting myself alongside," McIlroy said at the Bay Hill Club, where he is defending champion of the Arnold Palmer Invitational."So that's maybe a part of that; if I didn't know the history of the game and I wasn't such a fan, it would work in my favor.
