US Open 2013: Problems for Rory McIlroy but hard work will get him through

It's fair to say things have so far not gone to plan in 2013 for Rory McIlroy, who started the year as word No 1 and signed a huge deal with Nike, but it won't be long before he gets back in his stride.

"So he'll be out hitting balls for 45 minutes or so, driving and hitting irons, then he'll move out to the short game area and some putting, before doing nine or 18 holes and then coming back and working on anything that was wrong when he was on the course. "He's very focused on improving, so he'll always look at the trackman stats and ball flight and spin rates and so on and he's obviously worked hard on his fitness and specific golfing fitness work in the gym which we have here. "Everyone always talks about Rory's power, and it all comes from his hips and lower body rotation. He's got such quick hips and he can turn through so quickly that generates so much power, he's quickly than arguably any other player on Tour in that respect and that's where it comes from. "It's funny watching him, sometimes Michael Bannon and I have a chat about his swing and knowing them both as I do I hope sometimes I can offer some good suggestions for them on his swing. "Criticism of Rory was hard for Michael, as a teacher or a coach if your player's not swinging at his best you take some of the stick for that as well as the player, but he's been swinging it much better recently."
