Sania Mirza [Images] overcame a lapse in concentration in the second set to advance to the second round of the $200,000 Thailand Open in Bangkok on Tuesday.

The Indian teen sensation beat Slovakia's Henrieta Nagyova 6-1, 4-6, 6-0.

The fifth seed overpowered the 216-ranked Nagyova in the first set, but the Slovakian then capitalised on unforced errors by the Indian to squeeze out the second set 6-4.

Sania struck back with vengance in the decider to blank her opponent and set up a clash with China's Meng Yuan.

Yuan beat the higher-ranked Aiko Nakamura of Japan [Images] 6-2, 4-6, 6-3 in another first round match.

Sania also progressed in the doubles draw, teaming up with Israel's Shahar Peer to beat Carly Gullicksonn and Abigail Spers 6-2, 7-6.

Also advancing was third-seeded Argentine Gisela Dulko, who beat American Jamea Jackson 6-4, 7-5, while fourth-seeded Japanese Shinobu Asagoe was among the first-round losers.

Asagoe lost to Italian Antonella Serra Zanetti 7-6 (7-2), 6-4.

Veteran Spaniard Conchita Martinez advanced easily, whipping Thai crowd favorite Tamarine Tanasugarn 6-3, 6-2 as did France's [Images] Stephanie Foretz, who beat German lucky-loser Martina Muller 6-2, 6-0. Muller had replaced seventh-seeded Frenchwoman Marion Bartoli in the draw.
