Marta Kostiuk reaches Wimbledon semifinals under coach Sandra Zaniewska

Polish coach Sandra Zaniewska explained her partnership with Ukrainian tennis star Marta Kostiuk, stressing that “loyalty and trust… that I have for her, and the faith she has in me” are the foundation of their success. Kostiuk, benefitting from Zaniewska’s guidance, advanced to the Wimbledon semifinals after a straight‑sets win over Italy’s Jasmine Paolini (6‑3, 6‑2). The duo’s collaborative approach has propelled the Ukrainian player into the tournament’s final four, where she will vie for her first Grand Slam final appearance.

Zaniewska highlighted the importance of mutual confidence, saying it allows the coach to give the player “more space to convey exactly what she wants.” Their partnership is noted as one of the most successful coach‑player duos in women’s tennis this season.
