After taming Grand Slam winner Marat Safin, Prakash Amritraj was brought down to earth on Wednesday, losing in the second round at the $380,000 ATP Tour event in Los Angeles.
Playing as a wild card, Amritraj went down to Kenneth Carlsen of Denmark 4-6, 2-6.
Amritraj went through the first round on Tuesday after the former US Open champion conceded the match, citing a wrist injury.
A victory over Carlsen would have given Amritraj a chance to have a go at former world number one Lleyton Hewitt.
Amritraj later also lost his doubles match.
Pitted against top seeds Rick Leach and Brian Macphie of the United States, courtesy another wild card, Prakash and cousin Stephen Amritraj made a fight of it before going down 6-7 (5/7), 4-6.
In a $25,000 Challenger event in Denver, Davis Cupper Harsh Mankad too made his exit in singles play, losing 6-2, 3-6, 3-6 to home lad John Paul Fruttero in the second round.
Mankad, however, had better outing in the doubles with Arvind Parmar of Great Britain, winning 6-2, 6-3 against American Ryan Haith and Gonzalo Anguiano of Chile.
