Volkswacht Bodensee - Cirstea upsets Sabalenka in WTA Miami Open quarter-finals

Cirstea, ranked 74th in the world, triumphed 6-4, 6-4 against the Australian Open champion to secure her first WTA 1000 semi-final since Toronto in 2013.

The 32-year-old is enjoying an upturn in form since taking on Swede Thomas Johansson as her coach, reaching the quarter-finals at Indian Wells and beating world number four Caroline Garcia of France in both legs of the "Sunshine Swing."

In her first meeting with the big-serving Belarusian, Cirstea looked comfortable and composed as she broke Sabalenka's first service game.

The 24-year-old from Minsk, who is now based in Miami, broke back to make it 4-4 but Cirstea swiftly got back in front and held to win take the opening set with her opponent looking visibly irritated and frustrated.

Again Cirstea broke on her opponent's first serve game and then at 5-4 up, she survived two break points before a superb ace down the middle gave her match point, which she converted when Sabalenka went long.

The veteran reacted with a broad smile and a fist pump and conceded she was surprised by the victory.

"I think I am a bit speechless," she said. "I came out hoping that it would be a really tough match. I tried to hold my ground. I'm very happy with my performance today, it is a bit unexpected to be honest."

In the last four, Cirstea will face the winner of Wednesday's other quarter-final between Ekaterina Alexandrova and Petra Kvitova.
