Polish world number one Iga Swiatek defeated Chinese Zheng Qinwen 6-1, 6-4 in Stuttgart. She had been out for over a month with a rib injury.
Afterwards, she was critical of the International Olympic Committee's (IOC) decision to open up for Russian athletes to start competing again. "Nothing has changed in Ukraine, the cities are still under attack. It's heartbreaking," the star said after the match. Swiatesk has previously criticised those in power in tennis.
