Both the players registered straight-set wins in their respective round of 32 clashes.
Ramkumar Ramanathan had to play only one full set to progress into the round of 16 of the ATP Bangkok Challenger II.
After winning the first set in a tiebreak 7-5, Ramkumar Ramanathan was leading the second set 1-0 when his American opponent JC Aragone had to limp off with an injury.
Starting the first set on a positive note, the 15th-seeded player held on to his serve in the first two games before Aragone broke him to lead 3-2 following the fifth game. However, the Indian broke the American back instantly to bring parity in the set.
The pattern repeated in the 11th and 12th game of the set before it went to the tie-breaker. This time, however, the Indian broke Aragone twice.
Ramanathan held four set points before finally converting one, but the fifty-minute long first set had taken a toll on the American. Broken in the first game of the second set, Aragone could last only nine more minutes before leaving the court.
The Indian will next face Japan’s Go Soeda.
The other Indian playing in the singles event at the Bangkok Challenger was Sasi Kumar Mukund, who was up against a higher-ranked Paolo Lorenzi.
The third-seeded Italian was the favourite to advance from the round of 32 but Sasi Kumar Mukund, ranked 115 places below him, punched above his weight to win 6-3, 6-2.
Both the players held on to their serves throughout the first set until the eighth game, when Sasi Kumar Mukund broke Lorenzi to lead 5-3 and eventually win the first set 6-3.
The second set wasn’t very different either as Sasi Kumar Mukund always looked like breaking the Italian from the word go. After getting broken in the third game, Lorenzi had to save as many as three break points in the fifth game to stay alive.
However, Sasi Kumar Mukund broke the Italian in the seventh game yet again and sealed the match 6-3, 6-2 in straight sets.
