"There has been a high number of withdrawals at the Championships today and we sympathise with all the players affected.

The withdrawals have occurred for a variety of reasons but there has been some suggestion that the court surface is to blame.

We have no reason to think this is the case. Indeed, many players have complimented us on the very good condition of the courts," Lewis said in a statement Wednesday.

Various players, including former World No.1 Victoria Azarenka, pulled out of the only grass court major, citing injuries Wednesday.
