Murray on the up

Andy Murray has had universally good PR for the past few days. (Not often you can say that but his winning ways have done wonders for his rep).

As ever, Jonathan Overend was on the money this morning when giving his verdict on Murray. He listed Andy's achievements over the past four months which have seen Murray win two masters, reach his first grand slam final, reach No 4 in the world, and beat Federer, Nadal, and Djokovic. The guy is on a roll.

To his credit Murray is prepared to put in the graft. Something his PR and new media team have highlighted to great effect with photos and video on his website.

The hard work is paying off. On the evidence of the past week his serve is much improved. What was a major weakness is now one of his main strengths. Ditto his fitness.

If I was Djoko I'd be starting to get a little nervous, especially with all those points to defend in Melbourne.
