India's Mahesh Bhupathi and Rohan Bopanna advanced to the quarterfinals of the Madrid Open here with a hard fought three-set victory while Leander Paes and his Austrian partner Jurgen Melzer lost their match and bowed out in the pre-quarters.
Sixth seeds Bhupathi and Bopanna defeated the Argentine pair of Juan Monaco and Horacio Zeballos 6-3, 3-6, 10-5 Thursday to set up a quarterfinal clash with Jeremy Chardy of France and Lukasz Kubot of Poland.
Paes and Melzer didn't have such a good time and were easily ousted by German-Czech pairing of Tommy Haas and Radek Stepanek 5-7, 1-6.
The other Indian in the fray, Sania Mirza, was ousted along with her partner Bethanie Mattek-Sands in the second round, losing to unseeded Russian-Czech Anastasia Pavlyuchenkova and Lucie Safarova Wednesday.
