Rory McIlroy wins the US PGA Championship by eight shots

Northern Ireland's Rory McIlroy clinched his second major title in spectacular fashion, winning the US PGA championship by eight shots.

McIlroy dominated the field, carding a final-round 66 to roar clear of the pack.

His eight-stroke lead over England's David Lynn on five-under par is a record final lead in a US PGA Championship.

McIlroy also becomes the first player to complete a bogey-free final round at the tournament since Phil Mickelson in 2006.

A clutch of English players finished in credible positions including Ian Poulter and Justin Rose, who shared third place with Keegan Bradley and Carl Petterson.

The victory also propels McIlroy back to world number one and puts him in second place in the FedExCup standings.
