The top two seeds were upset in the WTA doubles semifinals on Thursday at the BNP Paribas Open.
Sixth seeds Martina Hingis and Yung-Jan Chan ousted top seeds Bethanie Mattek-Sands and Lucie Safarova, beating the Australian Open champions 7-6(7), 7-5 in just under two hours. Mattek-Sands won the title at the Indian Wells Tennis Garden last year alongside CoCo Vandeweghe.
In the second semifinal, Czech duo Lucie Hradecka and Katerina Siniakova beat Ekaterina Makarova and Elena Vesnina 6-3, 6-3. Vesnina was back on court for the doubles clash soon after her stunning singles quarterfinal win over Venus Williams.
In the ATP doubles semifinal action, sixth seeds Raven Klaasen and Rajeev Ram reached their second final of the season as they defeated Gilles Muller and Sam Querrey 6-2, 6-4. Klaasen and Ram captured their fourth ATP World Tour team title last month in Delray Beach (d. Huey/Mirnyi).
The second ATP doubles semifinal will be decided on Friday when fourth seeds Jamie Murray and Bruno Soares take on eighth seeds Lukasz Kubot and Marcelo Melo.
