Rory McIlroy was stumbling towards a third season without a major title as Jordan Spieth's faint hopes of becoming the youngest player to complete a career grand slam came to an end.

McIlroy came into the US PGA championship as the pre-tournament favourite on the back of top-five finishes in his last two starts and a brilliant record at the host venue Quail Hollow.
