Sania Mirza, who took a week off the circuit after the Bangalore Open, has slipped one spot to number 46 in the latest WTA Tour rankings.
The Indian star reached the quarterfinals in Bangalore where she lost to Russian Yaroslava Shvedova in three tough sets.
The 20-year old Hyderabadi returns to the circuit at the Qatar Open in Doha where she will take on Italian Romina Oprandi in the opening round.
Sania, however, improved two places to 26th in the doubles rankings.
Shikha Uberoi is the next highest ranked Indian, improving one spot to 231st in singles while dropping two places to 89th in the doubles charts.
Leander Paes and his Czech partner Martin Damm won their third career title together, beating Andrei Pavel of Romania and Alexander Waske of Germany 6-3 6-7(5) 10-7 in the final of the ATP event in Rotterdam.
Paes and Damm were runners-up at Doha last month to Mikhail Youzhny and Nenad Zimonjic.
However, the success did not help in improving their rankings with Paes (12th) and Damm (11th) holding on to their places. Mahesh Bhupathi clung on to 27th spot in doubles.
