World number one Rory McIlroy has said that he is frustrated with his second round at the US PGA Championship.
The defending champion scored a one-under-par round of 71 to leave him on two-under-par after two rounds, but he sits nine shots behind halfway leader Matt Jones.
He told Sky Sports News: "I felt like I played better than what the score reflected, so I'm a little bit annoyed.
"I felt like I should have got that ball up and down on seven and then I had a great chance on eight for birdie and didn't take that. A couple of days in a row where I haven't finished the round of golf the way I wanted to.
"I don't know if it's rust or I just didn't putt well, so maybe just work on that a little bit before I tee off tomorrow and it would be great to hole a few more putts, because I feel like I'm giving myself plenty of chances."
McIlroy is down in joint-28th place.
