'I think I have it figured out': Rory McIlroy says putting won't hold him back from career Grand Slam

Rory McIlroy insists his much-criticised putting is good enough to secure a first Masters title and complete a career Grand Slam.

McIlroy ranked a lowly 140th in strokes gained putting on the PGA Tour last year and suffered an embarrassing five-putt during the second round of the AT&T Pebble Beach Pro-Am earlier this month.
