Defending champion Sumit Nagal along with Asian Games bronze medallist Prajnesh Gunneswaran advanced to quarter-finals at the US$150,000 Bengaluru Open Tennis Tournament on Wednesday.
Nagal will meet compatriot Saketh Myneni, who also qualified for the quarter-finals.
Another Indian, who stormed into quarter-final is Sasi Kumar Mukund, who will play Gunneswaran in the next round.
The most enthralling match however was between Gunneswaran and German qualifier Sebstian Fanselow with the Indian prevailing 4-6, 6-4, 7-5.
Gunneswaran was initially not in his elements but served brilliantly in the second set. He won most of the points with his powerful forehands. He broke Fanselow once which was enough for the Indian star to win the set and level proceedings.
The third set saw as many as five breaks of serve. The Indian was 2-4 down after making two consecutive unforced errors in the sixth game. But he served well to claw back, hitting four of his five third-set aces in his last two service games to clinch the decider 7-5.
Gunneswaran will face Mukund, who reached the quarter-finals after his opponent Blaz Kavcic retired hurt while trailing 6-7, 1-3.
Earlier in the day, Nagal beat former British No 2 James Ward in straight sets 6-3, 7-6 (4).
In another match, Myneni beat Egyptian qualifier Youssef Hossam 6-1, 3-6, 6-1. Hossam had knocked out top seed Radu Albot in three sets on Tuesday.
