Stan Wawrinka is a prominent Swiss professional tennis player, achieving a career-high ranking of world No. 3. He is celebrated for his three major singles titles: the 2014 Australian Open, 2015 French Open, and 2016 US Open, remarkably defeating the reigning world No. 1 in each final. Beyond his Grand Slam successes, Wawrinka secured an Olympic gold medal in men's doubles with Roger Federer at the 2008 Beijing Olympics and was pivotal in Switzerland's 2014 Davis Cup victory.

Known for his powerful one-handed backhand, which John McEnroe lauded as "the best one-handed backhand in the game," Wawrinka's career trajectory led The Economist to describe him as "tennis's great latecomer," finding his peak success in his late 20s and early 30s. He officially shortened his name from Stanislas to Stan in 2014, a testament to his established presence in the sport.
