Thanks MatchPoint. It's good to get Andys version first hand.
I didn't notice anything that was affecting his movement but he certainly did lose his focus a bit at the beginning of the 2nd set, so if he tweaked a leg muscle that could explain it. At least I now know it was his hip and not his calf muscle, which is what has been reported elsewhere.
If Andy isn't worried about it, then I'm not either, but it's good that he's got a day between matches to let the problem settle and get his physio onto it.
And on the subject of his physio, I don't read anything into Andy Ireland's absence because I understand he has a family and probably wants to spend a bit more time with them.
Why do the posts always have to degenerate into childish comments?
Why not? We're all children at heart - or at least most of us are. Life is a serious enough business so it's necessary to lighten up occasionally otherwise we'd probably all go bonkers!
