Prakash Amritraj sealed a second round berth in the Wimbledon qualifying event but it was all over for Somdev Devvarman, who crashed out after losing his opening match in London on Monday.
Prakash, seeded 28 and ranked 161, beat Croatian world number 236 Antonio Veic 6-3, 6-4.
Somdev, seeded 14th, lost 3-6, 2-6 to Monaco's Jean-Rene Lisnard, who is ranked 80 rungs below the Indian at 215.
Prakash broke once in both the sets in the sixth game of the first and third of the second -- for an easy victory.
Prakash's game was flawless. He faced just two break-points in the match and successfully saved both.
He next faces either Conor Niland of Ireland or Daniel Cox of Britain.
Somdev had a disappointing day. Despite putting up a good fight he ended up on the wrong side.
The Indian began fantastically, breaking Lisnard in the first game of the match but suffered two consecutive breaks -- in the second and fourth games.
He had a chance to stage a comeback in the set when he earned a break-point in the ninth game and also saved two set points but the Monaco player did not let his guard down and warded off the threat.
The second set too started on a disastrous note for Somdev as he dropped serve. Lisnard broke him in the seventh game to create a 5-2 cushion and served out the match in the next.
