The fourth seed Indo-American took 65 minutes to send their rivals home.
They now face wild card entrants Elena Bovina and Alison Van Uytvanck. It was Sania’s 230th win in doubles. She also has 270 singles wins in her kitty.
But Sania failed to cross the first-round hurdle after losing 1-6, 5-7 to Monica Niculescu of Romania.
