So why is the German making news after a humbling loss at a WTA tournament in California?
Well, during that match, Lisicki blasted a 131 mile-per-hour (211 km/h) serve, setting the record for fastest serve in WTA tennis history.
Lisicki broke the mark previously held by Venus Williams. The American had owned the record since the 2007 US Open, when she fired a 129 mph (207 km/h) serve.
Have a look.
