Sania and Bopanna subdued Britain’s Andy Murray and Heather Watson with remarkable ease to breeze into the mixed doubles semi-finals with a 6-4 6-4 win in just 67 minutes.
One more victory will ensure India a silver medal and a defeat in the semifinals would give Sania and Bopanna a chance to fight for the bronze.
Sania and Bopanna were a better team than the Britons, who never posed a threat to the Indians.
