Stefanos Tsitsipas has decided to part ways with his father, Apostolos, as his coach following a heated confrontation during his shocking defeat by Kei Nishikori at the National Bank Open in Montreal. Tsitsipas, ranked No. 11 in the world, expressed his need for a coach who listens to his feedback and collaborates effectively, criticizing his father for not meeting these expectations. This decision follows a pattern of tension between the two, culminating in Tsitsipas asking his father to leave his seat during the match. Despite his frustrations, Tsitsipas expressed regret over his behavior and emphasized the importance of maintaining a father-son relationship. He has yet to announce a new coach ahead of the US Open.
