World number 41 Qiang Wang is through to her third WTA semi-final of the season and the second in a row following a commanding 6-4 6-0 win over the 21-year-old French Fiona Ferro in an hour and 26 minutes. The Chinese hit five aces and she fends off all six break points she faced to keep the pressure on her rival who could stay in touch with her only in the opening set before fading from the court in set number two.
Ferro served at only 49% and that wasn't enough to keep her safe in her service games, losing almost 50% of the points behind the initial shot and playing against 11 break points. Fiona had three break chances in the opening set in different games but she failed to convert any of those, managing to stay unbroken in the fifth game but falling down next time she served to send Qiang 4-3 up.
Serving for the set at 5-4, Wang repelled a break point to clinch the set and gain the momentum before set number two. It was all about Qiang there, taking all six games to secure the place in the semi-final in the best possible way.
The 23-year-old Bernarda Pera is through to her first WTA semi-final after a hard-fought 4-6 6-3 6-4 triumph over the 4th seed Aleksandra Krunic in two hours and 29 minutes. The American won just four points more than the Serb and she was much more aggressive, rushing to the net and scoring more winners but also more errors than her rival.
Krunic gave her best to stay in touch, saving 12 of the 20 break points she faced but it wasn't enough in the end, scoring six breaks from 13 chances she earned on the return. Aleksandra forged a 5-2 lead with back-to-back breaks before Bernarda broke back in game nine to prolong the set.
Nonetheless, the Serb broke at love in the following game to take the set 6-4 and nothing could separate them until 3-3 in the second set after Krunic saved two break points in the fifth game. Pera shifted into a higher gear to rattle off the last four games, breaking her rival in games seven and nine for a 6-3 and the chance to bring the match home in the decider.
There, Krunic was 3-1 up after a double break but Pera pulled it back with a break at love in game six, dominating on the return in the last three games to secure the win despite a poor service game when she served for the match at 5-3.
Krunic saved two match points in that game to break back but her initial shot betrayed her again in game 10 to send Pera in the last four. Quarter-final results:
