Masters champion Rory McIlroy made a somewhat scrappy start in his bid for back-to-back major titles in the 107th US PGA Championship.

McIlroy’s nerve-shredding victory at Augusta National made him just the sixth male golfer to complete a career grand slam and gave him a fifth major title, one behind Sir Nick Faldo.
