The first round defeat at the Binghamton Challenger proved too costly for Somdev Devvarman as the Indian dropped 23 rungs in the latest ATP ranking list to be placed 163rd even as Sania Mirza hung on to her 74th position in the WTA chart.

Somdev had lost to Sergei Bubka of Ukraine last week at the UAS tournament. Leander Paes though dropped one position to seven.

Sania, however, managed to maintain her 74th position in singles and imroved her doubles ranking to 46 from 49.

The Indian yesterday failed to qualify for the prestigious Rogers Cup after losing second round match.

Meanwhile, the Montreal Masters title win has pushed Mahesh Bhupathi to number eight position, gain of one slot.
