RAGU The Indian challenge in the singles event at the Chennai Open ATP Challenger fizzled out with the exit of Sumit Nagal and Sidharth Rawat in the second round at the SDAT Tennis Stadium here on Thursday. The India No. 1 took the first set against Russian Petr Bar Biryukov and appeared on course for a routine win when he began to flounder. He let slip three break-points in the second set which allowed his opponent to stay afloat. Once into the tie-break, the left-hander, ranked No. 305, used his big serve to good effect to push the match into the decider. Also, he raced to a 3-0 lead.
