Foot to the floor for McIlroy

Rory McIlroy vowed to “keep the pedal down” as he looked to turn a narrow halfway lead into a second major title in four weeks in the 96th US PGA Championship.

McIlroy, who is looking to become the first winner of back-to-back majors since Padraig Harrington in 2008, won his first two major titles by eight shots and led from start to finish to claim the Open Championship at Royal Liverpool last month.
