MADRID, Spain – Martina Hingis and Sania Mirza continued their serene progress at the Mutua Madrid Open, dispatching quarterfinal foes Andrea Hlavackova and Lucie Hradecka in little over an hour.

Since seeing their 41-match winning streak ended in Doha, Hingis and Mirza have endured a relative barren patch, going four tournaments without silverware. However, inside the Caja Mágica they are casting a spell over their opponents once again, bewitching No.6 seeds Hlavackova and Hradecka, 6-3, 6-2.

This masterclass set up a semifinal clash with a resurgent Vania King and Alla Kudryavtseva, winners of a far closer encounter in the preceding match on court. Taking on No.4 seeds Chan Hao-Ching and Chan Yung-Jan, King and Kudryavtseva recovered from a slow start to prevail, 2-6, 6-4, 11-9.

On the other side of the draw, Caroline Garcia and Kristina Mladenovic continued their fine clay court campaign with victory over No.3 seeds Timea Babos and Yaroslava Shvedova.

Garcia and Mladenovic arrived in the Spanish capital having won their opening two clay court events, Charleston and Stuttgart, and a 6-4, 6-3 victory over Babos and Shvedova extends their unbeaten streak on the surface to 11 matches.

Ekaterina Makarova and Elena Vesnina are the next team tasked with ending this run. French Open champions in 2013, Makarova and Vesnina advanced without striking a ball after Svetlana Kuznetsova and Anastasia Pavlyuchenkova withdrew when the latter failed to recover sufficiently from a thigh strain.
