Iga Swiatek played her first competitive match in two months yesterday, fighting back to make a winning start to her WTA Finals title defence. Swiatek beat Wimbledon champion Barbora Krejcikova, 4-6 7-5 6-2, in her first round-robin match in Riyadh.

Most tennis fans did not know what to expect in Sunday's WTA Finals match between Iga Swiatek and Barbora Krejcikova. Swiatek had not played since the US Open and shook up her coaching staff, while Krejcikova had only won five matches since her Wimbledon title.
