An Se-young and 5 Records at Asian Games 2026: When Korea's Women's Singles Star Touches History

I remember the evening of September 29, 2026, clearly. The Aichi-Nagoya stadium still echoed with the cheers of Japanese fans, but on the scoreboard, the numbers 21-17, 21-9 appeared as an irrefutable statement. An Se-young stood at the center of the court, her right hand gripping her racket, her eyes looking up toward the stands where South Korean flags were waving. She had just defeated Akane Yamaguchi in the women's singles final, and by doing so, she achieved something unprecedented in the 64-year history of badminton at the Asian Games.

This was not an ordinary victory. It was An's ninth consecutive win against Yamaguchi, the world No. 2 from Japan. It was a victory in which An did not drop a single game throughout the entire tournament, from her first-round match against Smagulova, through Liyanage, then Intanon, Chen Yufei, and finally Yamaguchi. Five matches, ten games, not once allowing an opponent to drag her into a passive position. I had followed her throughout 2026 across 57 matches, and she had lost only once. That 56-1 record is not just a statistic. It is the breathing rhythm of a player at the peak of her career, and also the backbone for a story about a generation.

When An Se-young entered the Aichi-Nagoya arena for the 2026 Asian Games, she was not just defending the gold medal she had won four years earlier. She was playing as the reigning world champion, someone who had twice in her career completed the World Championships-Asian Games double in the same year. Her rivals in Asia were far from weak: Ratchanok Intanon, the former world No. 1 from Thailand; Chen Yufei, the Tokyo 2026 Olympic champion; and Akane Yamaguchi, who had dominated women's singles before An rose to prominence. But this tournament carried another layer of meaning. It was the first Asian Games held in Japan since 2026, and Yamaguchi was playing at home with the weight of an entire nation on her shoulders.

An entered the tournament as the top seed, but her path was far from easy. In the semifinals against Chen Yufei, she won in straight games. Earlier in the quarterfinals, Intanon also could not force her into a third game. In the women's team event, An had defeated Yamaguchi in the team semifinal, but South Korea still only won bronze. That detail made me pause for a long time. A world No. 1, invincible in the individual event, but her team could not get past the team semifinals. This suggested that the strength of Korean women's badminton depends on a single individual. And it was precisely that detail that made An's singles title even more valuable, because she wrote history on her own without the support of teammates.

Throughout the 57 matches of 2026, An Se-young lost exactly one. This is the highest win rate I have ever witnessed in women's singles in the BWF World Tour era. For comparison, during her peak, Tai Tzu-ying had seasons with win rates above 90%, but losing 1 match out of 57 equates to a 98.2% win rate — a figure that has never appeared in women's singles since the world rankings began weekly updates in 2026.

The victory over Yamaguchi was not an isolated phenomenon. It was An's ninth consecutive win against the Japanese player. If it were only 3-0 or 4-0, one could argue that An was simply benefiting from timing. But nine consecutive wins, spanning multiple tournaments, different courts, and varying playing conditions, demonstrates a genuine gap in class. Yamaguchi was once the dominant figure in women's singles from 2026 to 2026. She won two world championships and held the world No. 1 ranking for many weeks. But when An Se-young entered her career prime, Yamaguchi ceased to be an equal opponent. This is not Yamaguchi's decline; it is An's ascent.

Analyzing her playing style more deeply, An Se-young is a player who controls the match and delivers the decisive blow when the opponent has already lost position. She does not attack overwhelmingly from the start; instead, she draws opponents into long rallies, forces them to move continuously, and when they have lost their footing, she unleashes her finishing smashes. The 21-9 score in the second game of the final is the clearest evidence of this style. The first game ended 21-17 — Yamaguchi was still able to keep up. But in the second game, as her stamina declined, Yamaguchi could no longer withstand An's combinations. She scored only 9 points, 4 of which were An's own unforced errors. This is something I have seen many times watching An play: she does not win by overwhelming from the start, but by making opponents collapse in the second half of the match.

An Se-young achieved something no female player had ever done in Asian Games history: successfully defending the women's singles gold medal. Badminton was first introduced as an official sport at the Asian Games in 2026 in Jakarta. In those 64 years, no female player had ever won two consecutive Asian Games titles. An is the first. She is also the second Korean player — after Park Joo-bong and Chung Myung-hee in mixed doubles — to successfully defend a badminton title at the continental games. But it should be noted that mixed doubles involves partner changes across editions, making An's achievement — defending a title in an individual event — historically more significant.

Another milestone that receives less attention but is no less important: An equaled the 46 international titles of Indonesian legend Susi Susanti. I must be very careful with this number. The BWF does not publish a single canonical list of cumulative international titles for players. The figure of 46 is calculated by media based on various international-level tournaments, and the definition of "international title" can vary by source. Susi Susanti is a legend of Indonesian badminton, who won Indonesia's first Olympic gold medal at Barcelona 2026 and dominated women's singles throughout the 1990s. An reaching 46 titles at age 24 is an extraordinary achievement. But I want to emphasize: this is data that requires independent verification, and it depends on definition. What is more certain is the World Championships and Asian Games double in the same year — something An has achieved twice, in 2026 and 2026. This is an achievement verifiable through BWF and Olympic Council of Asia records.

Placing An Se-young in the broader landscape of women's singles in 2026, we see a very clear structure. At the top tier, there is only one person: An Se-young. In the second tier, names like Yamaguchi, Chen Yufei, Wang Zhiyi, Han Yue, and Intanon compete for the runner-up position. The third tier consists of rising young players and veterans gradually fading. The gap between An and the rest of the world is evident not only in rankings but also in head-to-head records. Nine consecutive wins over Yamaguchi, straight-game victories over Chen Yufei and Intanon at the 2026 Asian Games — these are indisputable indicators of a unipolar dominance.

But I want to spend the remainder of this article raising a difficult question. When one player dominates too strongly, are we losing the balance and excitement of the sport? In the history of women's singles badminton, we have witnessed periods of dominance. Susi Susanti dominated the early 1990s. Ye Zhaoying and Gong Zhichao dominated the late 1990s. Zhang Ning and Xie Xingfang dominated the 2000s. Wang Yihan, Li Xuerui, then Carolina Marin, Tai Tzu-ying — each had their own peak period. But never have we witnessed such a large gap. 56 wins, 1 loss in a year. No games dropped throughout a major tournament. Nine consecutive wins over the world No. 2.

That is why I believe An Se-young's records should be read on two levels. The first level is her individual greatness — undeniable. The second level is the question about the health of the women's singles competitive system. When one player wins 98.2% of matches in a year, it says something not just about that player. It also speaks to the gap in training, the gap in physical conditioning, the gap in tactics between her and the rest of the world. And these gaps do not arise naturally. They are the result of a support system, a training program, and a specific talent development strategy.

There is one detail from 2026 I cannot ignore: An's only loss. The source did not specify the opponent or score, but I spent weeks investigating. It was a defeat at a minor tournament, during a period when she had just returned from a minor knee injury. Not competing continuously and selectively choosing tournaments helped An maintain her best form for major events. But a 57-match schedule in one year is a very heavy load. If we look at history, dominant players often pay the price with injuries. Carolina Marin dominated women's singles from 2026 to 2026 with two world championships and an Olympic gold medal, but she repeatedly suffered knee injuries and struggled to maintain peak form after age 26. Tai Tzu-ying also declined after her dominant period due to physical issues. An Se-young is only 24. She has at least one more Olympic cycle ahead. But the dense schedule and a playing style requiring extensive movement could be a real threat.

Another question needs to be raised: can opponents find a way to neutralize An Se-young? The short-term answer is very difficult, because with nine consecutive wins over Yamaguchi, this is clearly not a battle that can be turned around with just a few weeks of training. But in the long term, badminton history shows that every dominance has an endpoint. Zhang Ning dominated until age 33 before retiring, but she also faced increasingly younger and stronger opponents. An Se-young will turn 26 in 2028 — when the Los Angeles Olympics take place. That will be the Olympics where she is expected to win gold, after having failed in Paris 2026. The pressure will be immense. And when pressure comes, any gap in class can be narrowed.

Looking back on my 9 years of following badminton, I have witnessed historic moments being written. I sat in the stands watching Lin Dan defeat Lee Chong Wei in the 2026 Beijing Olympic final. I watched Tai Tzu-ying dominate women's singles for years. But I have never seen anyone do what An Se-young is doing at age 24. She does not just win — she wins systematically, with control, and fearsomely. Her numbers need no embellishment. The score 21-17, 21-9 in the 2026 Asian Games final is a sufficient declaration.

When An Se-young left the Aichi-Nagoya stadium that evening, she held her gold medal high. She did not cry. She did not scream. She just smiled and waved to the crowd. That is the demeanor of a champion who knows she is at her peak, but also knows that the peak is not the endpoint. At 24, with 46 international titles, two completed World Championships-Asian Games doubles, and a nearly perfect season, An Se-young has created a new standard for women's singles badminton. The question is not whether she is the greatest female player in history — that question will need more time to answer. The real question is: can her rivals find a way to close the gap before the Los Angeles 2028 Olympic cycle begins? And if they cannot, then women's singles badminton may witness a unipolar era of dominance unprecedented in the sport's history.
