Kohler (United States) (AFP) - Rory McIlroy couldn't improve on his opening round 71 on Friday, but the world number one wasn't giving up on his PGA Championship title defense.
"I felt like I played good in parts," McIlroy said after his second straight one-under round at Whistling Straits left him on two-under 142 and five shots off the mid-round lead.
