Top-seeds Sania Mirza and Martina Hingis entered the semifinals of the WTA Aegon International after coming from a set down to prevail over Hao-Ching Chan and Flavia Pennetta here.
The Indo-Swiss duo got the better of the unseeded combo of Taipei's Chan and Pennetta from Italy 4-6 6-3 10-6 in an-hour-and 13-minute quarterfinal contest of the USD 731000 grass court tournament, the last before the Wimbledon.
Sania and Hingis converted five out of the six breakpoints they got in the match, while their opponents could win just five out of 12 breakpoints.
In the semifinals, the top seeded pair will take on Caroline Garcia and Katarina Srebotnik.
