Stan Wawrinka has announced that 2026 will be his final year before retiring from professional tennis.

Wawrinka is a three-time grand slam champion, triumphing at the Australian Open in 2014, the French Open in 2015 and the US Open in 2016.

He defeated the then-world number one in all three of those finals (Rafael Nadal once, Novak Djokovic twice), while also winning an Olympic gold medal in doubles in 2008, partnering Roger Federer in Beijing. 

The 40-year-old has won 16 ATP Tour-level singles titles, with the most recent coming in his home country at the Geneva Open in 2017, while his last final ended in defeat at the 2023 Croatia Open.

Taking to social media on Friday, Wawrinka confirmed 2026 will be his final season in the sport, writing: "One last push.

"Every book needs an ending. It's time to write the final chapter of my career as a professional tennis player. 2026 will be my last year on tour.

"I still want to push my limits and finish this journey on the best note possible. I still have dreams in this sport.

"I've enjoyed every part of what tennis has given me, especially the emotions I feel playing in front of you. I'm looking forward to seeing you one more time, all around the world."

Wawrinka will likely need wildcards to appear at the majors during his farewell season, having slipped to 157th in the ATP Rankings following a series of knee injuries.

He has not been beyond the first round of a major since Wimbledon in 2024 (second round), only making the third round of two majors (Wimbledon and US Open, 2023) since a quarter-final exit at the 2020 Australian Open.
