(Reuters) - Poland's Iga Swiatek has split with her coach Piotr Sierzputowski after working with him for more than five years, the 2020 French Open champion said on Saturday.
Sierzputowski helped develop Swiatek's game from the junior circuit to the professional tour, leading her to the junior Wimbledon title in 2018 and the French Open Grand Slam two years later.
