Sania Mirza's poor singles form has seen her drop out of the top-50 in the latest WTA Rankings. The 19-year-old slipped 10 places to 54 in the rankings released on Monday.
French Amelie Mauresmo (3470) continues to lead the pack, followed by Belgium's Justine Henin-Hardenne (3078). Lindsay Davenport (1530) has dropped out of the top 10, slipping to the 11th position.
The Indian, who was ousted in the second round of the WTA tier IV Forest Hills Classic last week, has 424 ranking points. However, Sania managed to hold on to her career-high 28th position in the doubles rankings with 971 points.
Sania sits three steps below her first round US Open opponent Karolina Sprem (51) in the singles list.
Sania has made just one quarter-final appearance in the WTA events this year.
Among the other Indians in the list, the US-based Shikha Uberoi moved up two places to 191 in the latest rankings with 140.75 points. Shikha is followed by Ankita Bhambri (53.75) in 362nd spot.
In the ATP list, Leander Paes remains static at 12th spot with 2825 points, while his former partner Mahesh Bhupathi (1500) dropped one place to 27th in the latest doubles rankings.
