Vandeweghe and Koukalova had met last week in Birmingham Quarterfinals too, where Vandeweghe had served for the match in second set and had lost in the 3 sets to the Czech. The American talked about it as she said, "It was a good, clean match.
Last week I lost to her in a tough three-setter after serving for the match, so I definitely looked at it as a revenge match. To get that win in a semifinal is a really fun feeling. "I'm totally happy and elated. It's been a good year so far.
I'm looking forward to playing in the final." Vandeweghe will face China's Zheng Jie in the final, who brushed aside Magdalena Rybarikova in straight sets 6-1, 6-3.
Zheng Jie has not dropped a set yet this week.
