McIlroy delight at second major win

New world number one Rory McIlroy describes his second USPGA win on Sunday as "an incredible day".

"I went out to play solid golf and set myself a target of 12 under as I thought no-one would catch me if I reached that," said McIlroy.

"In the end, I went one better than that," said the 23-year-old, who won by a convincing eight shots from England's David Lynn at Kiawah Island.
