Take a look at this list of the TOP 40 players on the entry list for the 2006 Rogers Cup. Players in red (14) pulled out before or during the event. Players in yellow (20) lost in the 1st, 2nd or 3rd rounds. Players in green (6) reached the quarterfinals or better. I think this never happened before. The WTA Tour has to do something about all these withdrawals and these injuries.
