An Se-young's 47th title is not just a number, it is proof of a 10-match structural lock over Yamaguchi

An Se-young beat Akane Yamaguchi 21-23, 21-14, 21-18 in the Denmark Open final. It was her 47th international title, but the most striking thing I saw during the match was not on the scoreboard. In the deciding game, there was pain on An's face; she kept touching her taped ankle. I thought the match was about to end. Instead of stopping, she changed the pace of her movement and pushed the score from 9-12 to 16-12. This was no ordinary comeback. It was proof of the robustness of her playing structure, which did not break despite physical pain. This win is not just another title. It is part of a process that has centred women's singles around one player. An's record this season is 61-1, a 98.4 percent win rate. She is on a 44-match winning streak. And she has won 10 straight against Yamaguchi, including five finals. These numbers show this is not a fluctuation in form. It is a lasting structural advantage. I have watched this pair in women's singles closely for several years. Yamaguchi's strategy is clear: fast attack, maintaining pace in long rallies and breaking An's comfort in the first game. In the first game of the Denmark Open, she did exactly that. The journey from 18-15 to 21-23 was the result of Yamaguchi's aggressive play. But the problem is that she could not sustain that intensity across three games. The seven-point runs An built in the second game (11-13 to 21-14) and the third (9-12 to 16-12) show the depth of her defensive game. For me, the most important thing is that An did not change her shot selection; she changed her movement. When her ankle hurt, she pulled her positioning slightly back and created more space in the middle of the court to defend Yamaguchi's attacks. This shows the maturity of her system. A player who does not change the structure of her game even in pain is strong not only technically but mentally. A question arises here: is this streak against Yamaguchi the result of her playing style or of some weakness in Yamaguchi's game that An has identified? In my view, both. An's defensive coverage is so deep that Yamaguchi's aggressive shots often come to nothing at the end of rallies. But Yamaguchi has a route to winning a game, as she showed in the first game. The problem is that she cannot maintain that level for three games. That is the greatest strength of An's control-based game. Now let us come to the aspect the media may have overlooked. The Denmark Open final ended on 18 October and the French Open starts on 20 October. That is a gap of just four days. An has already played 61 matches this season and won nine titles. Her ankle problem surfaced in the deciding game. So the question is whether playing the French Open is right for her. From a records perspective, she can win 11 titles this season and equal Momota's 2026 record. But from a physical perspective, it is a danger signal. I have seen many players over the years who got injured while chasing records. An's case is different. Her playing structure is so strong that she can win even in pain. But over the long term, this structure can break under physical fatigue. The ankle is a joint that affects every aspect of her game. If she plays the French Open and the ankle worsens, the 44-match winning streak could end and the rest of the season could be affected. Another thing that emerged from this match is the Korean team's reliance on a single star. Apart from An, there is no Korean women's singles player who looks capable of replacing her in major tournaments. This is a structural risk. Japan and China have deeper bench strength, but Korea's entire burden rests on An. If she is injured, the entire Korean women's singles structure could be shaken. Now a fact that is often overlooked. An's only loss this season came against China's Wang Zhiyi in the All England final. This is a data point showing that a route to beating An exists. The strategy Wang employed was probably different from Yamaguchi's aggressive game. That is why, if Wang lands in An's half in upcoming tournaments, the match could be interesting. I am not saying An is unbeatable. But her dominance in women's singles right now is such that the others are fighting at a second level. Carolina Marin's retirement could widen this gap further, because she was one of the few players who could challenge An in a major final. Now the road ahead. The French Open starts on 20 October. For An, this is not just another tournament. It is a moment of decision. Will she chase the record or rest her ankle? In my view, the real test is not how many titles she wins but how long she stays at this level. An ankle injury is something that builds gradually and surfaces suddenly. If she plays the French Open and wins, it will be proof of her dominance. But if she loses or gets injured, the question will arise whether chasing records is right for her career. For me, this Denmark Open title is not just the 47th title. It is proof of the structural advantage An has built over the past few years. But it is also a signal of the physical limit her game has reached. The next few months will show how sustainable this advantage is.
