Yes he's just pulled out. but instead of cancelling the event an ehibition match is planned this evening between djokovic and murray! Personally I'd want my money back and would not want to sit through this meaningless nonsense instead.
Er... why exactly? What stone should he return to and why was he there in the first place?
Apart from being a superb tennis player Roger Federer is an excellent sport (I cannot recall ever seeing him cut up rough on the tennis court); he is polite and gracious when defeated; he has a fine family and really seems an all round good egg.
Just what do you have against him. Or is it simplky that he's successful, hard working and is worth a few bob?
