Hsieh Su-wei and Barbora Strycova both won previous meetings with Gabriela Dabrowski and Xu Yifan, heading for titles at Indian Wells last year and Madrid earlier in 2019.
Dabrowski and Xu were defending champions Barbora Krejcikova and Katerina Siniakova in this year's semifinals.
Hsieh and Strycova are not yet putting a set on this year's tournament looking to imitate Serena and Venus Williams, who won the title without losing a single set in 2009. Dabrowski and Xu have lost only one set along the way to today's showpiece.

Both couples are making their Grand Slam debut while Strycova will rise to Doubles No.1 if she helps win the title today – ending Kristinas Mladenovic's five-week reign. The Czech would be the 43rd woman to reach the top spot and seventh from her country.
Two of the last four Doubles finals at Wimbledon have gone to three sets.
Jelena Ostapeno's former Doubles final came on the Qatar Ladies Open last year as she collaborated with Dabrowski on victory over Andreja Klepac and Maria José Martínez Sánchez. She also won the St.Petersburg Ladies Trophy with Alicja Rosolska and Stuttgart Open with Raquel Atawo, both in 2017.
Latisha Chan has won two of her previous three Slam finals, winning the French open with Ivan Dodig last summer and this one. She also lost Australian Open showpiece in 2011 with Paul Hanley.
