"For the first time in his career, Jannik Sinner will compete at the 2025 Hamburg Open," tournament organisers confirmed on social media.
The 23-year-old agreed to a three-month ban in February after admitting "partial responsibility" for team mistakes which led to him twice testing positive for traces of the banned anabolic steroid clostebol in March 2024.
The reigning US Open and Australian Open champion's suspension ends on May 4th, allowing him to return in time for the French Open, the second Grand Slam event of the year.
The clay-court tournament in Hamburg will be Sinner's second event after his return as he will also compete on home soil at the Italian Open in Rome from May 7th-18th.
Sinner reached the French Open semi-finals last year. This year's tournament is scheduled to run from May 25th until June 8th.
