Djokovic was at his mind games. I think he was feigning his injury somewhat. But I was pleased with how Murray did (barring throwing away the 4th set in a matter of minutes). He showed mental strength that I didn't think he had. When he came back in the 5th I thought he would do it too.
I disagree with GS. Yesterday's match convinced me that there isn't that huge a gulf in class between Murray as 4th and Djokovic as 1st.
Murray did himself proud I thought. Bear in mind that Novak has lost 2 out of his last 80 odd matches or something mental like that.
