Mladenovic and Shuai will play Friday against the No. 7-seeded team of Jelena Ostapenko and Lyudmyla Kichenok, who lost to Hsieh Su-wei and Elise Mertens in this year's Australian Open final. Siniakova had swept the Grand Slam doubles tournaments since, winning the French Open title with Coco Gauff before teaming with Townsend to take the trophy at the All England Club.
