SINGAPORE - Garbiñe Muguruza and Carla Suárez Navarro produced a spectacular second set fightback to overcome Chan Hao-Ching and Chan Yung-Jan and secure a spot in the semifinals of the BNP Paribas WTA Finals Singapore presented by SC Global.
Having taken a close first set, Muguruza and Suárez Navarro looked to be heading for a match tie-break when they slipped a double break behind in the second. However, the Spaniards had other ideas, taking the next six games to complete a 7-5, 6-4 victory.
For the Chans, the disappointment was short-lived; in the evening session, their rivals for the other qualification berth, Bethanie Mattek-Sands and Lucie Safarova, retired when trailing 6-2, 3-0 against Caroline Garcia and Katarina Srebotnik.
The result means that the sisters, who had won their opening two round robin matches in straight sets, advance to the last four, where they will face the winners of the Red Group, which will be decided on Friday.
Garcia and Srebotnik, whose own qualification hopes had been extinguished by the earlier result, started brightly, breaking immediately when a sharp return pinned Safarova to the baseline. They soon stretched this lead, before wrapping up the set with a delightful flicked winner from Garcia.
Mattek-Sands, who began the match with her knee heavily strapped, called for the trainer at the changeover, and despite battling gamely on for a handful more games before calling time.
"It's a shame because I was hitting with Bethanie on one of the first days here and she was playing really well," Srebotnik said. "We saw she had strapping at the start, but it's always unfortunate to end a tournament like this."
