WTA rankings: Sania among top 50

Despite a second round exit at the Australian Open, Sania Mirza is back among the world's top 50 players by gaining five spots to be at 48th place in the latest WTA Tour rankings.

The 20-year-old Hyderabad girl defeated Ukrainian Olga Savchuk in the first round before going down tamely to Japan's Aiko Nakamura to bow out of the singles draw in the first tennis Grand Slam of the year.

Sania was benefited by the drop in rankings of Americans Shenay Perry and an out of scene Venus Williams, as well as Russian Elena Vesnina.

Shikha Uberoi, the next highest Indian in the rankings, dropped 20 places to be 228th.

Australian Open champion Serena Williams has a steep climb from 81st to 14th place while beaten finalist Maria Sharapova of Russia took over the top ranking from Belgian Justine Henin-Hardenne.

Sania, who teamed up with Spaniard Anabel Medina Garrigues to make it to the third round in women's doubles, gained two spots to be at 23rd position. Shikha is the only other Indian in the top 100 at number 92.

Among the men, Leander Paes, who did not have a great run in Melbourne in partnership with Czech Republic's Martin Damm, dropped two places to 12th on the ATP rankings.

Mahesh Bhupathi, who reached the quarterfinals with Czech Radek Stepanek, rose two spots to 27th.
