Duval still believes McIlroy can banish Augusta demons

Former world number one David Duval believes Rory McIlroy will complete the career grand slam, but fears that his latest bout of Masters misery will be tough to take.

McIlroy began the final round three shots off the lead and closed to within a shot of eventual winner Patrick Reed after two holes, but faded badly with a closing 74 at Augusta National.

And although it was not the collapse of 2011, when he enjoyed a four-shot lead after 54 holes before crashing to a closing 80, the Irishman has now failed to convert his first four chances to join Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus and Tiger Woods in winning all four majors.
