Sania Mirza [Images] climbed back to her career-high singles ranking of 70, thanks to her splendid showing at Wimbledon.

The Indian ace, who reached the second round of the ladies' singles, where she lost US Open champion and World No. 6 Svetlana Kuznetsova, jumped five places to get back to her best ever ranking, which she also achieved in the last week of May.

The Hyderabadi's ranking had slipped marginally to 75 following a couple of early losses in the clay court season, including the French Open, when she was returning from an eight-week injury lay-off.

At Wimbledon, however, Sania was at her best. She defeated Japan's [Images] Akiko Morigami, then ranked 71, in the first round before threatening to give Kuznetsova a run for her money in the second.

The 18-year-old is at present back in Hyderabad and, after more than a week's practice, will leave for the United States on a seven-week sojourn culminating with the US Open Grand Slam, starting August 29. She will be accompanied by new travelling coach John Farrington.

Her North American hard court season schedule includes the following WTA Tour events:

July 18: Cincinnati (prize money of $170,000, Tier 3)

July 25: Stanford ($585,000, Tier 2)

Aug 1: San Diego ($1.3 million, Tier 1)

Aug 8: Los Angeles ($585,000);

Aug 15: Toronto - Canada [Images] ($1.3 million).
