The highlights of their 2014 season came in Rome, where they won their 10th WTA doubles title as a team, and in Doha, where they reached the final (falling to Hsieh Su-Wei and Peng Shuai).
They've also reached the quarterfinals or better at three of the four Grand Slams this year, their best showing being the semifinals of the Australian Open (falling to Sara Errani and Roberta Vinci).
Peschke and Srebotnik, who won Wimbledon in 2011 and subsequently became the co-No.1s in doubles, will be playing the WTA Finals for the third time together, having made the final in both previous attempts in 2010 and 2011. Peschke is playing in this event for the fifth time overall, Srebotnik her eighth.
"We are so happy to have qualified for the WTA Finals in Singapore," Srebotnik commented. "We came so close in 2010 and 2011. We hope we can find that spark this year, and with a bit of luck anything can happen. We can't wait to experience all Singapore has to offer on and off the court."
"Kveta and Katarina are an established doubles team with proven success," said WTA Chairman & CEO Stacey Allaster. "With six teams now qualified, the doubles field at the BNP Paribas WTA Finals Singapore presented by SC Global is shaping up to be a spectacular assembly of the best teams in the sport."
Peschke and Srebotnik join Errani and Vinci, Hsieh and Peng, Ekaterina Makarova and Elena Vesnina, Cara Black and Sania Mirza, and Raquel Kops-Jones and Abigail Spears in the field.
The battle for the last two spots could wrap up soon.
