Former world number one: I expected a lot more from Rory McIlroy

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.
