Stanislas “Stan” Wawrinka (French: [vavʁiŋka]; born 28 March 1985) is a Swiss professional tennis player.
He has won two Grand Slam singles titles in his career: the 2014 Australian Open and the 2015 French Open, and has reached a world ranking of no. 3, obtained on 27 February 2014 and held for several months. He also won an Association of Tennis Professionals (ATP) Masters 1000 tournament at the Monte Carlo Masters in 2014, and was a finalist at the Rome Masters in 2008 and the Madrid Masters in 2013. Furthermore, he won a gold medal for Switzerland in the men’s doubles event at the 2008 Summer Olympics, partnering with Roger Federer, and was part of the Swiss team that won the Davis Cup in 2014. He played in the longest doubles match in history at the Davis Cup tie against the Czech Republic in 2013, partnering with Marco Chiudinelli.
He is one of the few active players on tour to have reached the quarterfinal stage of all four Grand Slams. He is also one of only three players (alongside Tomáš Berdych and Jo-Wilfried Tsonga) to have Grand Slam wins against each of the Big Four (namely Roger Federer, Rafael Nadal, Novak Djokovic and Andy Murray). Stan is the second player after Roger Federer to defeat Rafael Nadal and Novak Djokovic in two successive grand slam finals. He has two wins against reigning world number one players in his career, both happened to come in the final (over Nadal in Australian Open 2014 and over Djokovic in French Open 2015) of the two slams he has won.
Wawrinka considers clay his best surface and his serve and backhand his best shots. John McEnroe once said that Wawrinka has one of the most powerful backhands ever, and in 2009 described him as having “the best one-handed backhand in the game”.
Just prior to the 2014 French Open, he requested and the ATP granted a formal change in his name from “Stanislas Wawrinka” to “Stan Wawrinka.” He stated that he plans to use the abbreviated name in tournament draws and press conferences.
