Jovanovski won four straight games from 5-3 down in the second set in her 61 75 victory. Break point chances was the key stat, as Jovanovski converted on all four on Schmiedlova's serve and saved four of five on her own.
"I started really well," Jovanovski said. "I was serving very well, returning well and playing aggressively. In the second set she started to play some longer points and put pressure on my serve. I was a little bit unlucky on my break points early in the set, but I managed to come back in the end and I'm happy to win the match.
"It's my first time here. I really like the city and it's a very nice tournament. I'm looking forward to coming back next year."
Jovanovski has now won nine of her last 10 matches dating back to the start of Tashkent, where she captured her second WTA title. Next up for her is Johanna Larsson, who advanced when Johanna Konta retired before the third set of their quarterfinal because of a stomach muscle injury.
Meusburger was a 62 64 winner over seventh-seeded Yaroslava Shvedova and has surrendered just 10 games through three matches, least of the semifinalists. She also is 17-4 in her last 21 matches.
Zhang rallied from two breaks down in the second set and a 5-1 deficit in the tie-break for a 64 76(10) defeat of Anabel Medina Garrigues. Having secured her first WTA title in Guangzhou, Zhang has won eight consecutive matches in straight sets, including a 61 61 rout of Meusburger last week.
Zhang, partnering Chan Yung-Jan this week, was also among those advancing to the doubles semis.
