The only Indian Woman to win a WTA event, Sania had slipped three places after her lacklustre performance at the Sunfeast Open in Kolkata but she more than made up for it by her show in Japan.

Sania's climb up the ladder continued in the doubles also where she moved 14 places to reach 114.

Paired with Israel's Sahar Peer, Sania had made it to the semifinal of the Japan Open, which saw her WTA points go up to 343.50.

In men's singles tennis, Harsh Mankad moved seven places to reach 227 and remained the highest ranked Indian.

In doubles, Mahesh Bhupathi [Images] and Leander Paes [Images] fell one place each to lie in 13 and 15 places respectively.
