China’s top player Zhang Shuai lasted barely 90 minutes in this year’s Indian Wells Masters singles draw in California, before she was eliminated by world No 58 Marta Kostyuk in three sets at tennis’ unofficial “fifth slam”. Zhang, the world No 48, went down 6-1, 1-6, 6-2 to the 19-year-old and leaves Zheng Saisai as the only Chinese player left in the singles draw. She meets Polish qualifier Magdalena Frech in her first assignment on Thursday night. The 32-year-old Zhang has endured a mixed 2021 campaign, which has seen her singles world ranking slip from a high of 30 last season. She has enjoyed far more success in women’s doubles this term. Alongside Indian partner Sania Mirza, the Tianjin-native claimed the Ostrava Open title last month. That came just two weeks after she sensationally claimed a second grand slam victory with Samantha Stosur at the US Open in New York. Her first grand slam doubles crown was won, also alongside Stosur, at the Australian Open in 2019.
