Sania Mirza and her Polish partner Marta Domachowska sailed into the second round with an easy 6-4, 6-3 win over the South African-Venezuelan pair of Natalie Grandin and Milagros Sequera in the 175,000 dollar Cincinnati Open.
The third seed Indo-Polish pair will now take on the unseeded pair of Uzbek Varvara Lepchenko and Chinese Meng Yuan, who beat the Russian-Georgian duo of Vasilisa Bardina and Salome Devidze.
Sania will also start her singles campaign later on Tuesday against American Alexandra Stevenson.
The Indian teen and her Polish partner capitalised on the mistakes committed by their opponents and broke them thrice before comfortably clinching the first set.
The second set also took little effort from Sania and Marta as they smashed 35 winners on thier way to sealing the match in their favour.
Among the other Indians in the fray, Shikha Uberoi and her Canadian comrade-in-arms will be up against the top seed Italian-Argentine pair of Maria Elena Camerin and Gisela Dulko in their first round match of the women's doubles.
Shikha has already dropped out of contention in the singles competition after her first round loss in the qualifiers.
