17 July, Chandigarh
India have defeated South Korea 4-1 in the Davis Cup Asia\Oceania Group I tie in Chandigarh on Sunday.
Playing his first Davis Cup singles match in four years, Rohan Bopanna edged past Hong Chung in a tough match.
Asked to take court in place of Saketh Myneni, who is still recovering from his gruelling match on Friday, Bopanna laboured to a 3-6, 6-4, 6-4 win against Chung.
Ramkumar, however, lost the close contest 3-6, 6-4, 6-7.
India will now make its third attempt to qualify for the elite 16-nation World Group. India last played in World Group in 2011 when it lost the first round against Serbia.
After that, they have lost play-offs twice – against Serbia (in 2014, Bangalore) and Czech Republic (in 2015, New Delhi).
