India's Sunitha Rao bowed out of the $ 170,000 WTA Pattaya Open in Thailand, going down in straight sets to Russian Ekaterina Bychkova in the second round on Thursday.
The Indo-Japanese pair was beaten by the Hungarian-Ukrainian combination of Melinda Czink and Yulian Fedak at the Sunfeast Open.
The 34-ranked third seeded Indian ace proved too good for the 283-ranked Japanese in the first round of the Sunfeast Open.
