Zealous Zhu sends Petra packing in Tianjin
China's Zhu Lin staved off a spirited mid-match comeback to upset Petra Kvitova for her first top-20 victory in the opening round of the Tianjin Open on Wednesday.
The unseeded 23-year-old from Wuxi, Jiangsu province, beat the two-time Wimbledon champion 6-4, 5-7, 6-4, then followed up by beating Hsieh Su-wei of Chinese Taipei 6-3, 6-1 on Thursday.
Kvitova was the first to blink in her first meeting with Zhu, handing her rival the chance to break at 4-4.
