ANNING, China - Top seed Peng Shuai put together a dominant display against Elitsa Kostova, dropping just one game on her way to the semifinals at the 2018 Kunming Open, a WTA 125K Series event in Anning, China.

Peng’s serve was the key to her fearsome form; she faced just one break point all match long, and in the second set she dropped just one point in all of her service games.

The Chinese player needed just under an hour to seal the victory and make her way into the semifinals, where a familiar foe awaits in Zheng Saisai.

Although Peng owns a 4-1 lead in the pair’s head-to-head record, that lone loss against Zheng is still fresh - just a few weeks ago at Zhengzhou 125K, Zheng stunned top seed Peng in the opening round to claim her first career victory over her countrywoman.

In contrast to Peng’s straight-sets cruise, No.4 seed Zheng made her way into the semifinals after a hard-fought three-set battle against Frenchwoman Amandine Hesse.

After seeing her 5-1 lead in the opening set erased by a determined Hesse, Zheng kicked into high gear to take the second and third sets, winning 5-7, 6-1, 6-1 after two hours and 21 minutes.

Joining them in the semifinals are Irina Khromacheva - who also came back from a set down to knock out No.3 seed Yanina Wickmayer, 2-6, 6-3, 6-3 - and No.7 seed Han Xinyun, who upset No.2 seed Wang Yafan, 6-3, 2-6, 6-4.
