McIlroy relishing career slam chance

World number one golfer Rory McIlroy tells BBC sports editor Dan Roan achieving the career grand slam would "mean an awful lot".

The 25-year-old Northern Irishman McIlroy would complete a career grand slam with a green jacket on 12 April.

He won the US Open in 2011, the US PGA in 2012 and 2014 and last year's Open at Royal Liverpool.
