The lone Indian left in fray at the ATP Challenger Series' SAIL Open, Ashutosh Singh crashed out after a straight-sets loss to Australian Colin Ebelthite in a rain-interrupted second round match of the US $50,000 tournament. The wildcard local favourite, who stunned eighth seed Alexandre Kudryatsev of Russia in the opening round on Tuesday, was handed a 4-6, 4-6 defeat by Ebelthite, bringing the curtain down on the Indian challenge in the singles.
