After a week of stability, Sania Mirza again plummeted two rungs on the rankings ladder to be placed 69th on the latest WTA Tour chart.
The Indian tennis sensation, who was out of action for around a month, has 382 singles points.
Sania, who last played in the Bangkok Open where she lost in the singles first round, has resumed her practice last week ahead of the six-nation Hopman Cup to be staged in her home town of Hyderabad, where she will play along side Leander Pace in the mixed doubles.
Sania, who had confessed during the recent Sunfeast Open in Kolkata that fitness was not her forte, has said she was perfectly fit to play any number of tournaments now.
In the doubles, Sania was steady at 25th with 1070 points.
Among the men, Paes slipped out of the top-10 list.
He lost two places to be 12th while Mahesh Bhupathi was lying constant at 31st on the ATP computer.
