McIlroy career grand slam only a matter of time, says Clarke

Ryder Cup captain Darren Clarke believes it is just a matter of time before Rory McIlroy completes the career grand slam by winning the Masters.

McIlroy is aiming to claim his third major in succession at Augusta next month and become only the sixth player to have won all four major titles after Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus and Tiger Woods.
