Rory McIlroy 'feeling good' ahead of PGA Championship

Rory McIlroy says he is "feeling good" ahead of the defence of his title at the US PGA Championship at Oak Hill.

The Northern Irishman has struggled this year with a string of poor results following a multi-million dollar change of equipment and legal issues with his management company.

McIlroy clinched his second major by eight shots at last year's Championship at Kiawah Island.
