What is the Fastest Serve Ever Recorded in the WTA?
Sabine Lisicki (Germany) clocked 131 mph (210.8 km/h) on a speed gun while serving in the first set of a first-round match against Ana Ivanovic at the Bank of the West Classic tournament at Stanford University, California, USA, on 29 July 2014. A 129-mph (207.6-km/h) serve by Venus Williams (USA), recorded in a second-round match against Ashley Harkleroad at the 2007 US Open, was previously the fastest serve by a woman on the WTA (Women's Tennis Association) tour, although Brenda Schultz-McCarthy (Netherlands) sent down a 130-mph (209.2-km/h) serve in qualifying for the Western & Southern Open in Cincinnati, Ohio, in 2006 that wasn't recognized by the WTA because it happened outside of the main draw.
After setting the record, the defeated Lisicki tweeted: "Well...at least I broke the world record for fastest serve on @WTA ... #131mph #history #record."
