Third-ranked Rory McIlroy and American Colt Knost each closed with bogeys to spoil course record bids in Friday's second round of the US PGA Players Championship. McIlroy fired an eight-under-par 64, failing to match the TPC Sawgrass mark of 63 despite opening with five birdies and an eagle in his first seven holes, while Knost missed a four-foot par putt at 18 that would have given him a 62. "I was nervous over that last putt," Knost said.
