Winning WTA finals is far from a new trend for the Taiwanese-Chinese duo, as they are now 8-0 in them. In fact, their winning ways started right away, as they were victorious in their first two events as a combination in 2008 and 2009.
"I feel very comfortable playing with Su-Wei," Peng said. "We've known each other since we were very young."
Hsieh and Peng won a couple more titles in 2009, but then none the next two years. However, they have collected four titles since Rome in May, most on the WTA in 2013. And during that span they have compiled a 23-3 record.
Hsieh and Peng's 2013 heroics may very well result in their first TEB BNP Paribas WTA Championships berth, as coming into this week they ranked fourth in the standings.
"There are not too many tournaments before the Championships," Peng said. "We'd like to win as many as possible and gain more points."
One of those tournaments is this week in Tokyo, where Hsieh and Peng are the No.1 seeds. Whatever happens with the Istanbul berth, it has been a memorable year for them, with their first Grand Slam title at Wimbledon their crowning achievement.
"I was very happy to win Wimbledon this year," Hsieh said. "That should allow me to focus more on enjoying tennis. Playing tennis shouldn't be pressure. I want it to become an enjoyable part of my life."
Interestingly enough, this week's other WTA doubles winners were also a Taiwanese-Chinese pairing, as Chan Chin-Wei and Xu Yi-Fan captured their first WTA title in Seoul with an upset of No.1 seeds and defending champions Raquel Kops-Jones and Abigail Spears in Sunday's final. It was the first WTA title of any kind for Chan and Xu.
