"It's very hot today and a tough game, but we play well," Mirza said after the match.
The reigning Wimbledon and US Open champions broke serve five times to clinch the match in just over an hour. Up next for the dynamic duo will be a pair of hometown favorites as former top-ranked junior Xu Shilin and partner You Xiaodi upset No.2 seeds Anatasia Rodionova and Klaudia Jans-Ignacik, 7-6(5), 6-3. Xu and You thrilled the Centre Court crowd as they saved all four break points faced in the second set to take the match in straight sets.
Hingis and Mirza were first into the final, but were feeling optimistic that they could capture a sixth title of the season, putting themselves in even better stead ahead of the BNP Paribas WTA Finals Singapore presented by SC Global.
"We don't know who will be our opponent yet, but we'll prepare everything," Hingis said. "I am so happy to go to the final in my first time in Guangzhou. Look forward to tomorrow's final."
With one team bringing star power and another national pride, it should be quite an exciting coda to the doubles tournament, which will take place following the singles final between WTA Rising Star Denisa Allertova and No.4 seed Jelena Jankovic.
