India endured a torrid opening day at the Davis Cup Qualifiers 2nd Round in Seoul on 18 September 2026, with both Dhakshineswar Suresh and Sumit Nagal squandering first-set leads in three-set thrillers at the Olympic Tennis Court. Korea's Soonwoo Kwon and Hyeon Chung staged dramatic comebacks to put the hosts in an commanding 2-0 lead, placing India on the brink of elimination.

Kwon Turns the Tide Against Suresh

The afternoon session opened the day's damage when Kwon overhauled Suresh in a 4-6, 6-3, 6-4 victory, handing the Indian his first Davis Cup singles defeat. Suresh had broken Kwon in the very first service game and looked composed on a warm, cloudy afternoon as the home favourite struggled to find his footing on the slow court.

The momentum shifted decisively in the second set when Kwon began attacking Suresh's serve early, drawing four double faults from the Indian before converting a break in the sixth game to level the match. In the decider, Kwon broke again in the sixth game, reached match point in the ninth, and closed out the contest in the next game despite Suresh saving once.

'I felt a lot more nervous than I have in a long time,' Kwon said after the victory. 'At the beginning, my vision was almost blurred. From the second set onward, I began to feel more relaxed. In the second set, I was able to read those [serving] patterns and hold my return position to one side, which helped me play much better.' Kwon finished with seven aces and an impressive 92 per cent first-serve points won.

Chung Grinds Down Nagal in Three-Hour Battle

The evening session offered India a lifeline when Nagal — the country's top-ranked singles player — raced to a 4-0 lead against Chung. But the Korean mounted a relentless fightback, eventually prevailing 2-6, 6-4, 7-5 in three hours and five minutes to seal the day for Korea.

Nagal dominated the opener, breaking Chung twice and serving out from 5-2, though Chung saved four set points along the way. A tightly contested second set swung on a single moment: Nagal double-faulted to surrender a 4-3 lead, allowing Chung to break back and then break again to level at one set apiece.

The decider fluctuated throughout, with momentum switching repeatedly, before Nagal double-faulted once more at 5-5 to hand Chung a match point — which the Korean duly converted. 'When I was broken at 3-3 in the second set… I thought my opponent might feel the pressure of wanting to close out the match,' Chung reflected. 'At 5-5 in the third set, there was no real strategy left. We had both been playing for more than three hours, so it became a battle of mental strength.'

Korea One Win From Historic Quarter-Final

The result means Korea need just one more victory across the three remaining rubbers — the doubles and two reverse singles on Saturday — to reach their first-ever Davis Cup quarter-final. This is the closest the hosts have come to that milestone in the competition's history, a fact that gave the partisan Olympic Tennis Court crowd much to celebrate.

India's Must-Win Saturday

India must sweep all three remaining rubbers to salvage the tie — a tall order given the mental and physical toll of Friday's defeats. Saturday's play begins with the doubles rubber before the two reverse singles matches. Notably, both Suresh and Nagal lost despite leading in their respective matches, underlining the resilience of the Korean pair rather than any collapse from the Indian side. With home advantage, crowd support, and momentum firmly on Korea's side, India will need exceptional performances to turn the tie around.
