LONDON - German Sabine Lisicki sent another seismic shockwave through Wimbledon on Monday when she dumped five-times champion Serena Williams out of the tournament with a 6-2 1-6 6-4 fourth-round upset.

Top seed Williams, overwhelming favourite for the title with her chief rivals already out, squandered a winning position as the resilient Lisicki, no novice on a grasscourt after reaching the 2011 semi-finals, refused to capitulate in front of a stunned Centre Court crowd.

Williams appeared to have averted danger when she reeled off nine successive games to lead 3-0 in the decider but Lisicki rallied with a gripping fightback.

After breaking to nose 5-4 ahead, the 23rd seed showed no stage fright by securing victory on her second match point to set up a last-eight meeting with Estonian Kaia Kanepi.

"I am still shaking, I am so happy," Lisicki told the BBC as Williams followed second and third seeds Victoria Azarenka and Maria Sharapova out of a championship that is confounding expectations.

"Serena played a fantastic match, she is such a tough opponent. It is an amazing feeling to win this match. This is such a special place for me and the crowd were brilliant to me.

"I gave it everything I had, I fought for every single point to try to win it somehow. I'm not thinking about the next match yet."
