Martina Hingis won in her return to the WTA Tour, teaming with Daniela Hantuchova for a 6-1, 6-1 victory over Julia Goerges and Darija Jurak on Wednesday in the Southern California Open.
The ‘Swiss Miss’ has retired twice previously, the first time in early 2003 at 22 and the last time in November 2007.
In singles, Ana Ivanovic advanced to the second round by beating defending champion Dominika Cibulkova 4-6, 6-3, 6-2.
The seventh-seeded Ivanovic, from Serbia, won nine of the final 11 games. She used a strong ground-game to overpower Cibulkova, the Slovak coming off a victory on Sunday in the Bank of the West Classic at Stanford.
'As soon as the draw came out I thought it was one of the toughest first-round matches, especially being a seeded player,' said Ivanovic, the former top-ranked singles player and 2008 French Open champ. 'But I was really happy with my performance.'
Top-seeded Victoria Azarenka of Belarus beat Italy’s Francesca Schiavone 6-2, 6-3 in the second round. Azarenka was playing her first match since withdrawing from her second-round match at Wimbledon because of knee and hip injuries.
'Just going on the court and competing was so much joy for me,' Azarenka said. 'I was really playing and happy to be doing something I was training for. . . . I don’t think about it (injuries).'
Ivanovic, who fired coach Nigel Sears after her second-round loss at Wimbledon, said she has been working on 'being consistent and also working on that confidence part. It plays a big role. I felt like my game has been there at times but not my confidence.'
Third-seeded Petra Kvitova of the Czech Republic and fourth-seeded Roberta Vinci of Italy had few problems in winning their opening matches after receiving first-round byes.
Kvitova advanced to the quarterfinals with a 6-1, 6-2 victory over British teenager Laura Robson. The victory avenged Kvitova’s second-round loss to Robson at the Australian Open in January.
Vinci beat American Bethanie Mattek-Sands 6-4.
