New Delhi, June 26 (PTI): Her not-so-impressive build up to Wimbledon notwithstanding, Sania Mirza's ranking improved by a couple of rungs in both the singles and doubles WTA charts released yesterday.

The Indian ace, who crashed out in the first round of last week's Ordina Open, rose to 44th in the singles list while her doubles standing also improved to 40th.

The 20-year-old Hyderabadi opens her campaign at the All England Club against Russian Yaroslava Shvedova.

Though grass remains Sania's favourite surface and she starts as favourite against the 80th ranked Shvedova, the Indian's recent form makes it a tricky opener for her.

Sania would be teaming up with Israeli Sahar Peer in the women's doubles and Mahesh Bhupathi in the mixed doubles.

Meanwhile in the ATP doubles rankings, Leander Paes dropped a rung to ninth, while Bhupathi remained static at 20th.

Paes will continue his partnership with Czech Martin Damm at Wimbledon where the duo has been seeded fifth.

The pair finished runner-up at last week's Ordina Open.

Bhupathi would also continue to partner Czech Radek Stepnak at the All England Club and the combination has been seeded 11th.
