China’s interest in the WTA Tenerife Ladies Open ended on Friday as Zheng Saisai and Zhang Shuai both lost as the season heads to its final two tournaments. Chinese No 3 Zheng was beaten by Colombian teenager Camila Osorio in straight sets with the 19-year-old winning 7-5, 6-1 in an hour and 42 minutes. This was the first career meeting between the world No 86 Zhang and world No 63 Osorio. Osorio had beaten No 1 seed Elina Svitolina in the first round and then Egypt’s Mayar Sherif, while Zheng entered the quarters after a thrilling three-set win over Danish No 7 seed Clara Tauson.
