Sabine Lisicki “Upskirt” Winner vs Sharapova on Day 7 of Wimbledon 2012

Sabine Lisicki booked a fourth-round date with Maria Sharapova and has refused to rule out making a complaint if the Russian’s grunting becomes unbearable.

The hard-hitting German claimed a 7-6, 1-6, 6-2 triumph over up-and-coming American Sloane Stephens as she moved to replicate her efforts of 12 months ago when she reached the semi-finals.

Blocking her path is Sharapova, who brushed aside Su-Wei Hsieh 6-1, 6-4 in double-quick time on Centre Court. And Lisicki now faces the issue of whether to complain about the noise coming from the other side of the net, as she did during her victory over Bojana Jovanovski earlier this week.
