The second seeded Indo-Australian pair needed just 55 minutes to defeat their American rivals 6-0 6-4 in the quarter-finals of the USD 220,000 clay court event.
Sania and Rodionova saved four breakpoints in the match and converted five of the chances they got.
They will now fight it out with Kazakhstan's third seeded pair of Yaroslava Shvedova and Galina Voskoboeva for a place in the final.
