'Frustrated' Rory McIlroy on World Match Play final defeat

World number two Rory McIlroy tells the BBC's golf correspondent Iain Carter of his "frustration" at losing the WGC Match Play final 2&1 to Hunter Mahan.

The 22-year-old Northern Irishman beat Lee Westwood in the semi-final and victory would have seen him take the coveted World number one spot, an eventuality he describes as "inevitable" if his early-season form continues.
