Jannik Sinner to Compete in Hamburg ATP Tournament After Doping Ban Ends

World number one Jannik Sinner will return to competition at the Hamburg Open from May 17-24, 2025, after serving a three-month doping ban that ends on May 4. The ban followed his admission of partial responsibility for team errors leading to positive tests for the anabolic steroid clostebol in March 2024. This appearance will mark Sinner's debut at the Hamburg tournament, which is part of his preparation for the French Open, where he reached the semi-finals last year. Prior to Hamburg, he will compete in the Italian Open in Rome from May 7-18. Sinner's suspension was a result of a settlement with the World Anti-Doping Agency, following an appeal against a previous exoneration by the International Tennis Integrity Agency. Additionally, Sinner has announced changes to his management team, appointing longtime friend Alex Vittur to oversee his business affairs.
