Sania Mirza would gun for another upset win against Anna-Lena Groenefeld of Germany whom she has been drawn to play against in the first round of the USD 170,000 WTA Western and Southern Financial Group Women's Open tennis starting in Cincinnati on Monday.

Sania, who has climbed up to five places to 70th rank after her impressive show in the Wimbledon, has a tough task in hand against the seventh seeded German, currently ranked 36 in the world.

The Tier-II WTA tour event, Sania's first in the run up to the US Open Grand Slam starting on August 29, will also test the Indian's skill on hard court.

Sania, who would be accompanied by her travelling coach John Farrington, would be hoping to pull off a win against the German whom she had defeated in the semifinals of the Palm Beach Garden Challenger last November.

Switzerland's Patty Schnyder is seeded top while Vera Zvonareva, Jelena Jankovic and Daniela Hantuchova follow on second, third and fourth positions. Sania is unseeded.

American-born Indian Shikha Uberoi has been seeded fifth and will face Seiko Okamoto of Japan in the first round of the qualifiers.
