STANFORD, Calif. -- The WTA says Sabine Lisicki has hit the fastest serve in the history of the women's tennis tour, reaching 131 mph (211 kph).
Lisicki hit the record serve at 5-5, 40-30 of a first-round loss against Ana Ivanovic in the Bank of the West Classic on Tuesday. Ivanovic got her racket on the ball, but the attempted return landed wide.
The previous fastest WTA serve was 129 mph (208 kph), by Venus Williams at the 2007 U.S. Open.
Lisicki, a 24-year-old German, was the runner-up at Wimbledon in 2013.
