You know the end of the season is here ad players are falling left and right with injuries. Justine Henin ended her season then Venus Williams then Svetlana Kusnetsova and probably Serena Williams too.
A bunch of other players have also been hit with injuries and end of season tired mode it seems. Refael Nadal has not played well enough since winning the US Open.
Just lots of tired people working hard to see the end of the 2010 tennis season.
