CINCINNATI, OH, USA - Chan Hao-Ching and Chan Yung-Jan won their fourth WTA doubles title together at the Western & Southern Open on Sunday, and by doing so now have the second-most WTA doubles titles for a pair of sisters in WTA history after only Serena Williams and Venus Williams.
Their previous three WTA doubles titles came at Shenzhen in 2013, Eastbourne in 2013 and Pattaya City earlier this year. Cincinnati represents their biggest one yet - their first at the Premier 5 level.
They broke a three-way tie with the Bondarenko sisters (Alona and Kateryna) and Pliskova sisters (Karolina and Kristyna) and now trail only the Williams sisters, who have won 21 WTA doubles titles.
"It's difficult to explain how exciting it is," Yung-Jan said. "As sisters, sometimes it shows your best strengths to play together, and sometimes you also have bad times playing together, but we have conquered the bad times and we're playing great tennis together, especially this week.
"This trophy will help us a lot with our confidence going into the US Open."
Unseeded, the Chan sisters had a string of great wins. After upsetting No.3 seeds Caroline Garcia and Katarina Srebotnik in the second round, they outlasted former No.1s Sara Errani and Flavia Pennetta in the quarterfinals, 6-7(4), 7-6(1), 19-17, which featured the longest match tie-break of the year.
They were told about the longest match tie-break of the year stat after the final.
"I think that's pretty awesome," Yung-Jan said. "Thankfully I didn't feel that sore after it!"
They were asked afterwards what worked so well in the final. "First of all not fighting!" Yung-Jan replied. "Also, we were trying to play aggressive. Our dad has been coaching us very well. We've been doing some great practice, specifically at the net and baseline, and everything is working well.
"They played really well, too. The first set they were ahead, but we kept thinking we had nothing to lose, and we came back. We stayed aggressive and we're happy we won the first match point."
