MIAMI, FL, USA – Margarita Gasparyan and Monica Niculescu produced a stirring second set comeback against Vania King and Alla Kudryavtseva to become the first team into the doubles semifinals at the Miami Open.

Twenty-four hours earlier, Gasparyan and Niculescu had sent shockwaves through the draw by outclassing top seeds and defending champions Martina Hingis and Sania Mirza. However, when they slipped 5-2 behind in the second set, hopes of building on this upset looked to be hanging in the balance.

The seeming inevitability of a match tie-break seemed to liberate the Eastern Europeans who played some swashbuckling tennis in far from ideal conditions to draw level then close out a 6-3, 7-6(3) victory.   

“I think we played our best match today, it was a very good win,” Niculescu said. “I was thinking it was going to be a very tough match. It’s not easy to beat No.1s in the world yesterday and then to come here – we know King won two Grand Slams.

“We’re happy to come back – it was a good win, we stayed focused, tried to stay aggressive. It was starting to rain a bit and was also very windy and now we’re in the semifinals! I’m so happy!”

Gasparyan and Niculescu’s previous two outings together ended in second-round defeats in Doha and Indian Wells, and the identity of their semifinal foes will not be revealed until Wednesday, when No.4 seeds Timea Babos and Yaroslava Shvedova take on Kateryna Bondarenko and Olga Savchuk.

In the bottom half, Xu Yi-Fan and Zheng Saisai face Ekaterina Makarova and Barbora Strycova, while in the opening match on Stadium court No.3 seeds Bethanie Mattek-Sands and Lucie Safarova take on fellow Grand Slam winners Andrea Hlavackova and Lucie Hradecka.
