Asiad 20: Thuy Linh pushes world No.4, Hai Dang exits in badminton third round

The second game ended with a cross-court smash from the left side. 24-22. Nguyen Thuy Linh had just leveled her match against world No.4 Chen Yu Fei in the third round of Asiad 20. The cheers on the stands burst out and quickly faded when the umpire confirmed the score. That moment was not just a game win; it was a rare signal that Vietnamese badminton could stand on the continental stage without being purely defensive. But the full picture of the competition day on September 26 was not all bright. In men's singles, Nguyen Hai Dang - who had just beaten Odilzhon Abdurakhmanov 21-6, 21-6 in the previous round - could not repeat that ease against Kunlavut Vitidsarn, one of Thailand's top players. He lost 16-21, 14-21 in a match where the opponent controlled almost the entire tempo. This result raises questions about the gap between Vietnam's singles level and Asia's elite group. My analytical framework has often repeated: the space never lies - we just need to be calm enough to listen. The Thuy Linh match against Chen Yu Fei is a clear example. In the first game, she lost 10-21 because her defensive line was too low, allowing Chen to repeatedly choose cross-court angles. In the second game, the adjustment came when Thuy Linh pushed forward, forced her opponent to the backcourt, and used the 45-meter gaps on both sides almost perfectly. She did not win through power, but through timing. The turning point was the deciding game at 12-21. If we only look at the score, we could say Chen Yu Fei was simply superior. I want to look deeper: the deciding game was a battle of physical foundation and concentration. Thuy Linh began to be slow in moving back to the court, and her returns lost depth. That was not a tactical collapse, but an imbalance between effort and recovery time between games. The match ended on the scoreboard, but it was truly decided by the off-the-rally movements at minute 42. For Nguyen Hai Dang, the 21-6, 21-6 win over Odilzhon Abdurakhmanov created conditional optimism. The opponent had a lower ranking and was not the type of player who could sustain a long pace. When facing Kunlavut Vitidsarn, what happened was a lesson in intensity. Kunlavut did not need to press loudly; he simply kept the shuttle to the backcourt and made Hai Dang constantly late. The two games of 16-21 and 14-21 tell a story: Hai Dang has enough skills to score, but not enough consistency to maintain continuous pressure against an elite defensive unit. My pressing data, if applied to badminton, would draw the map of an entire team's will. Here, that map shows Hai Dang attacked actively in the first ten minutes of each game, then allowed Kunlavut to re-establish order. One blind spot many people miss is the difference between a game won because the opponent eased off and a game won through sustainable tactics. Thuy Linh took advantage of Chen Yu Fei's carelessness in the second game, but when the opponent returned seriously in the third, she no longer had enough tools. The question is what would happen if she faced another top-10 player in a tournament with three matches in three days? My historical data from previous Asiad rounds shows that Vietnamese players often win one opening or middle game, but very rarely win the whole match against top-5 opponents. This is not a matter of single technique, but of the ability to maintain quality over three games. Hai Dang also falls into that risk zone. The 21-6, 21-6 win over Abdurakhmanov creates a beautiful statistic, but that statistic does not reflect the true level. If we remove the factor of a weak opponent, Hai Dang's data shows that he can only maintain high intensity for about 25 minutes. Kunlavut exploited this exact weakness by extending rallies, forcing Hai Dang to move across all four corners continuously. What we need to track is not the score of dominant wins, but the ability to convert physical advantage into points against opponents who know how to extend the match. A team does not need to excel in every position; it just needs no link to be forgotten. At Asiad 20, Vietnamese badminton had no reported team medals. Both Thuy Linh, Hai Dang, and the other players reaching the third round were an individual phenomenon, not a system one. This reveals a reality: Vietnam's youth training resources still depend on outstanding individuals rather than on squad depth. Looking at strong teams like China or Thailand, they have at least two options for each singles event. Vietnam currently has one, or with luck two, and when one of them meets a top-4 opponent, there is no plan B. Looking back at Thuy Linh's loss to Chen Yu Fei, I believe the 24-22 moment will be mentioned for months. But if we are honest with the data, the 12-21 third game is a warning. Chen Yu Fei did not need to change anything special; she just waited for Thuy Linh to run out of energy. I have witnessed this in many Southeast Asian players during my years of following Asian tournaments: they have good tactics for one game, but no system for the whole match. That is not something a single fitness session can solve; it is a matter of designing the entire training curriculum, from nutrition in the tournament week to energy distribution within each game. For Hai Dang, the match against Kunlavut could be a significant milestone. He saw clearly the rhythm, the movement, and the patience of a top player. Losing 16-21, 14-21 is even more positive than a whitewash of 6 points, because it shows he can reach that score range. The question for the coaching staff is: how to turn this 10-point gap into a 5-point gap, then into a game win? This requires a tournament roadmap with regular top-20 opponents, not waiting for the Asiad every two years. Asiad 20 can be a useful test, but it should not be the only place to measure level. Vietnamese badminton needs to think about building a regular international schedule for Thuy Linh and Hai Dang. Not necessarily expensive Super 1000 events; Super 300 and Super 500 events can also provide opponents ranked in the top 15. From my experience tracking matches in many Asian countries, the more players face strong opponent groups, the more they learn to manage energy and adjust tactics mid-match. The empty court turns out to be the most perfect laboratory in modern badminton: the spaces on court are where individual tactics and coaching coordination appear most clearly. Thuy Linh's second-game win by moving into the forehand space of Chen Yu Fei is a classic example of reading the match. But that space did not appear by itself; it was a product of observation and risk-taking. It is still too early to talk about major progress. Thuy Linh has sometimes beaten lower-ranked players, but the loss to Chen Yu Fei shows that improving rankings requires more than a beautiful game. Hai Dang, with his dominant win in the previous round, also needs more than one match to prove that he can overcome himself against big opponents. Do not just save the image of 24-22; save the lonely moments in the third game behind the court, when the muscles begin to react and the spirit must still stand. Thuy Linh's match was not decided in the second game but at the end of the third, when Chen Yu Fei carefully picked up each shuttle and suffocated every comeback chance. In the long-term view, the lack of a layer of opponents ranked between 10 and 25 is the biggest barrier. Thuy Linh met Chen Yu Fei early because of the ranking and the knockout format of the Asiad. To go further at continental games or the Olympics, she needs conditions to play this group of opponents many times a year. Similarly, Hai Dang needs to establish a competitive relationship with players like Kunlavut or Lee Zii Jia, who have cold controlling styles. Each meeting is a small step in learning to resist the boredom that top players create. I do not draw a pessimistic conclusion, but I want to ask an open question to Vietnamese sports managers: is the national badminton development strategy designed to nurture individuals like Thuy Linh and Hai Dang into a group, or does it still rely on the random emergence of a talented generation? The answer will decide whether the 24-22 moment is a flash of light passing across the Asiad sky, or the foundation for a Vietnamese badminton that dares to think big and stand longer on the continental stage.
