New York, Aug 26 - India's Somdev Devvarman won his first round in his bid for a place in the US Open tennis main draw, beating American Alex Bogomolov Jr 6-3, 6-3, but Prakash Amritraj lost to Colombian Alejandro Falla 6-7 (5), 6-4, 3-6, here at Flushing Meadows.

Somdev, ranked 161, beat the 133rd ranked American of Russian origin for the second time in a month Tuesday, having beaten him to qualify for the LA Open late last month, also in straight sets.

Prakash's fight-back against Falla, who is ranked 31st for the qualifiers, was of no avail as he lost a tight first-set tie-break, won the second but could not carry the momentum into the third.

Somdev's victory is an upset of sorts as Bogomolov was seeded 16th in the qualifiers.
