Updated: Wikipedia source
Stanislas "Stan" Wawrinka (French: [stanislas vavʁiŋka]; born 28 March 1985) is a Swiss professional tennis player. He has been ranked as high as world No. 3 in singles by the ATP. Wawrinka has won 16 ATP Tour-level singles titles, including three majors at the 2014 Australian Open, 2015 French Open and the 2016 US Open, where he defeated the world No. 1 player in the final on all three occasions. He has also won an Olympic gold medal in men's doubles at the 2008 Beijing Olympics partnering Roger Federer, and was pivotal in the Swiss team's victory at the 2014 Davis Cup.
Wawrinka's other achievements include reaching the final of the 2017 French Open, winning a Masters 1000 title at the 2014 Monte-Carlo Masters, and reaching three other Masters finals (at 2008 Rome, 2013 Madrid and 2017 Indian Wells). He considers clay his best and favorite 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 deemed it "the best one-handed backhand in the game." He has been described by The Economist as "tennis's great latecomer", owing to finding his greatest success in his late 20s and early 30s. Prior to the 2014 French Open, he requested and was granted a formal change in his name from "Stanislas Wawrinka" to "Stan Wawrinka", stating that he plans to use the abbreviated name in tournament draws and press conferences.
