US PGA Championship day one: Rory McIlroy struggles and Corey Conners soars

Rory McIlroy faced a battle to make the halfway cut in the US PGA Championship on Friday after finding himself in familiar and unwelcome territory at Kiawah Island. McIlroy, who won by eight shots the last time the tournament was staged on the Ocean Course in 2012, struggled to an opening three-over-par 75 to lie eight shots off the lead held by Canada's Corey Conners.
