Stefanos Tsitsipas’ struggles continued at the Japan Open, where he suffered a surprising first-round loss to American Alex Michelsen. The Greek star, ranked No. 12 in the world, lost in straight sets despite winning the first set. This latest defeat follows a string of disappointing performances for Tsitsipas, who has announced a coaching change and is dealing with burnout. Meanwhile, other notable matches saw Jack Draper advance and Yoshihito Nishioka prevail in a marathon three-set encounter.
