Peng will also team up with Zhang in the doubles event. While Chinese tennis tandem Zheng Saisai and Xu Yifan will take China's other women's doubles spot in Rio.

Peng fell at the opening round of the ongoing 130^th edition of the Wimbledon Grand Slam in London, United Kingdom. The Chinese tennis ace lost to the tournament's 18th-seeded Sloane Stephens of the United States in two-straight sets 7-6 (7-5), 6-2 on Wednesday, June 29.

Peng, who was a 2014 U.S. Open semifinalist, is still recovering from a waist surgery she underwent in May last year, according to Xinhua.  The female tennis player currently holds the 264^th spot in the WTA's world rankings for singles and sits on the 147^th place in doubles.

"I am really honored to represent the country to play in the Olympics. I don't know for sure if my form will be back to top at that time but I will try my best, even if the recovery is slow," Peng, who started tennis at the age of eight, said.

Peng is known in the tennis world for her stamina and plays with her two hands. She has defeated many top players including Maria Sharapova, Agnieszka Radwanska, Martina Hingis, Ana Ivanovic, Jelena Jankovic, and Anastasia Myskina.
