CHENNAI, India - Matthias Bachinger of Germany upset seventh-seeded Yen-Hsun Lu of Taiwan 6-4, 3-6, 6-4 Tuesday at the Chennai Open.

Bachinger needed a little more than two hours to stave off a spirited rally from 2010 Wimbledon quarterfinalist Lu in a baseline slugfest that turned out to be the highlight of a day.

Also advancing to the second round were fifth-seeded Benoit Paire of France, German qualifier Cedrik-Marcel Stebe, Roberto Bautista Augut of Spain and India's Prakash Amritraj and Somdev Devvarman.

In the deciding third set, Bachinger broke serve in the fifth game and held to go up 4-2 before playing out the match.

Amritraj, son of former Indian Davis Cup player Vijay Amritraj, continued his form in the qualifying tournament by beating Frenchman Guillaume Rufin 6-7, 6-2, 6-3.
