Sabine Lisicki, German tennis player
Sabine Katharina Lisicki (German pronunciation: [zaˈbiːnə lɪˈzɪki]; born 22 September 1989) is an inactive German tennis player who turned professional in 2006. Her breakthrough was in 2009 when she reached the quarterfinals of the Wimbledon Championships, and also won her first title on the WTA Tour, at the Family Circle Cup.

In March 2010, she suffered an ankle injury at the Indian Wells Open that kept her out of competition for five months and saw her fall out of the top 200.

Lisicki rebounded in 2011 and won the Eastbourne Classic before entering the Wimbledon Championships as a wildcard and going on to reach the semifinals, where she lost to Maria Sharapova. In doing so she became only the second woman in Wimbledon history to make it to the semifinals while entering the tournament as a wildcard. She followed that two months later by winning her third WTA tournament, the Texas Open. In 2012, she achieved her career-high ranking of world No. 12 and again reached the quarterfinals of Wimbledon. Again, in 2012 she suffered from another ankle injury that prevented her from having better results on tour. Lisicki reached the final of the 2013 Wimbledon Championships, losing to Marion Bartoli. The following year, she had another quarterfinal at Wimbledon and won her first title in three years when she won the Hong Kong Open.

In doubles, Lisicki won the Porsche Tennis Grand Prix in 2011 with Samantha Stosur and in 2013 with Mona Barthel and the 2014 Miami Masters with coach Martina Hingis. She also reached the doubles final at Wimbledon in 2011 with Stosur and came fourth in the mixed-doubles event at the 2012 London Olympics with Christopher Kas.

Between 2014 and 2018, Lisicki held the world record for the fastest serve by a female tennis player. A 131.0 mph (210.8 km/h) serve was measured during her first-round encounter against Ana Ivanovic at the 2014 Stanford Classic. She also held the record for the most aces in a singles match, hitting 27 aces during her second-round encounter against Belinda Bencic at the 2015 Birmingham Classic, until it was surpassed by Kristýna Plíšková at the 2016 Australian Open.
