India’s top singles player Sumit Nagal believes the upcoming Davis Cup qualifier against South Korea could ultimately be decided by sheer determination, noting that the slow court conditions will become increasingly demanding as the day goes on.

Nagal is scheduled to take on South Korean star Hyeon Chung in Friday’s second singles match. The tie will begin with Dhakshineswar Suresh facing Korea's highest-ranked singles player, Kwon Soon-woo, in the opening fixture. Nagal anticipates a tough battle against Chung, an opponent he knows well from past practice sessions and doubles partnerships.
