Lucie Šafářová (Czech pronunciation: ; born 4 February 1987) is a Czech tennis player from Brno. She has won seven WTA Tour singles titles, 15 doubles titles and reached the quarterfinals of the 2007 Australian Open by upsetting defending champion Amélie Mauresmo in the fourth round. She reached her first Grand Slam semifinal at the 2014 Wimbledon Championships and her first Grand Slam final at the 2015 French Open. She also won the 2015 Australian Open, 2015 French Open, 2016 US Open, 2017 Australian Open and 2017 French Open women's doubles titles partnering with Bethanie Mattek-Sands.
Šafářová plays left-handed with a two-handed backhand and possesses a high topspin forehand similar to that of male tennis star Rafael Nadal. Her timing off the ground allows her to project groundstrokes with power, and she is quick to spot opportunities to take the initiative. Šafářová is notorious for having a volatile return that is capable of hitting clean winners, as well as unforced errors. Her preferred surface is clay. She was coached by Rob Steckley until September 2016 when she split with him, ending a coaching relationship of more than three and a half years, and hired František Čermák. In December 2017, Safarova announced that she is reuniting with Rob Steckley for the 2018 season.
