A resilient Somdev Devvarman saved a match point before wearing out German Michael Berrer in the opening round of the ATP Zagreb Indoor event on Wednesday.
The Indian overcame a poor start as he was bageled in the first set but eventually won 0-6 7-6 (6) 4-1 when his German rival, world number 125, retired due to fatigue.
Somdev, known for playing long matches with a never-say-die spirit, kept Berrer in the match with his amazing retrieving ability.
Somdev, who is leading a players' revolt against the national federation, next plays fourth seed and world number 29 Austrian Jurgen Melzer in the euro 410,200 event.
It will be first meeting between the new players.
