Stan Wawrinka will hope for an emotional farewell to the Australian Open in January when the popular former champion begins what he's announced will be his final year in tennis.
The 40-year-old Swiss star, who managed to win three grand slams including the 2014 Open at Melbourne Park amid an era dominated by the sport's 'big three', declared on Friday that he'll hang up his racquet at the end of 2026.
