Wawrinka, who turned professional in 2002, won 16 tour-level titles and reached a career-high world ranking of number three in 2014. His grand slam victories came against the then-world number one in each final: he beat Rafael Nadal for the 2014 Australian Open title and defeated Novak Djokovic for the 2015 French Open and the 2016 US Open. At the 2008 Beijing Olympics, Wawrinka paired with Roger Federer to win the doubles gold for Switzerland, and the duo helped Switzerland win its first Davis Cup title in 2014.
Ahead of his final match, Wawrinka told the ATP Tour website: "For me, all I wanted in my career was to give everything, to have no regrets, to always fight, to always give 100 per cent in every match — out of respect for myself, for the opponent, for the tournament, for the fans, for everybody. That was always the most important thing for more than 20 years, and that's the only way you can leave the sport: without any regrets."
The 41-year-old’s last shot as a professional, a backhand that landed wide, drew audible disappointment from the home crowd in Basel, bringing an end to a career defined by resilience and high achievement.
