SINGAPORE - Seeded No.3 after a stellar second half of the season, sisters Chan Hao-Ching and Chan Yung-Jan went head-to-head with No.2 seeds Bethanie Mattek-Sands and Lucie Safarova who, with titles at the Australian Open and French Open, had dominated the first half. Both won their opening matches at the BNP Paribas WTA Finals Singapore presented by SC Global, but it was the Chans who remained undefeated on Tuesday, easing past Mattek-Sands and Safarova, 6-2, 6-2.

"We were facing two Grand Slam champions, and they've had such a good year," Chan Yung-Jan explained after the match. "We had to put 100% into the match to even have the possibility of winning, so it's definitely some of the best tennis we've played."
Winning in just over an hour, the Chans won their fourth straight set in Singapore, saving all three break points faced to give themselves the strongest case to reach the semifinals.
"I think compared to the start of the season to now, our confidence is really high; we're just looking forward to our next match," Chan Hao-Ching said.
Finishing up round robin play, the Chan sisters have only to play Carla Suárez Navarro and Garbiñe Muguruza, who got their first win of the week against No.5 seeds Caroline Garcia and Katarina Srebotnik. The No.8 seeds trailed Garcia and Srebotnik 1-4 in the first set before turning things around in emphatic style, breaking serve twice in the second to keep their semifinal hopes alive.
"It was crazy; I don't know how many set points we had," Muguruza said of the crucial final game of the first set that went to multiple deuces. "We just tried to be calm and wait for our moment."
"We won the first set, so it was much easier to play a really good second set," Suárez Navarro added.
The Spaniards beat the Chans in their one prior meeting in 2015, which came in the final of the Toray Pan Pacific Open to snap the sisters' seven-match winning streak after they won the Japan Women's Open Tennis the week before.
Doubles round robin action continues on Wednesday featuring the Red Group, with No.4 seeds and WTA Rising Stars Timea Babos and Kristina Mladenovic going head-to-head against No.6 seeds Raquel Kops-Jones and Abigail Spears, while top seeds Martina Hingis and Sania Mirza close the night against No.7 seeds Andrea Hlavackova and Lucie Hradecka.
