SERENA WILLIAMS has warned her Wimbledon rivals there is more to come after demolishing Jarmila Groth on Court One yesterday.

Wimbledon promises to be a quieter place after former champion Maria Sharapova made a second-round exit for the second successive year.

Elena Dementieva stretched her winning run to 12 matches as she booked her place in the third round of the Australian Open with a 6-4 6-1 win against Iveta Benesova.

The opening day of Wimbledon 2004 may have been blighted by rain, but two former champions used the breaks in cloud to shine at SW19.
