An Se-young’s 21-3 Routing of Shim Yu-jin Cements Her Reign as Badminton’s Queen
SINGAPORE — The badminton world witnessed history Sunday night as World No. 1 An Se-young delivered a clinical 21-3, 21-3 demolition of her Korean compatriot Shim Yu-jin in the Singapore Open’s opening round, a performance that underscored her status as the sport’s undisputed queen.
The match, a Korean Derby that captivated fans, was never in doubt. Se-young, who recently completed her career Grand Slam by winning the 2026 Asian Championships, moved into the tournament’s 16th round with authority, her serve-and-volley game and relentless aggression leaving Shim—ranked No. 12 in the world—nowhere to hide.
Why This Match Was a Statement
Se-young’s victory wasn’t just another win—it was a declaration. Coming on the heels of her Asian Championships triumph, where she defeated China’s Wang Ziyi in the final, this performance solidified her position as the most dominant force in women’s singles badminton. The 24-year-old, who also claimed Olympic gold in Paris earlier this year, now boasts an unmatched career: 432 wins, 75 losses, and a world No. 1 ranking she’s held since August 2023.
Key context: Se-young’s 21-3 scoreline is one of the most lopsided in recent BWF Tour history, joining legendary performances like Carolina Marin’s 21-11, 21-16 win over Ratchanok Intanon in 2015. The match’s brevity—just 18 minutes of play—highlighted Se-young’s ability to dictate terms from the first serve.
How It Unfolded: A Tactical Breakdown
The match followed a predictable but devastating script. Se-young, coached by Lee Hyun-il, began with her signature serve-and-volley approach, forcing Shim into defensive errors on the first three points. By the 5-1 mark, it was clear Shim—who had beaten Se-young just once in their career (2020)—was overwhelmed by the pressure.
Game 1 (21-3): Se-young’s net play was lethal. She converted 12 of 15 smashes, while Shim’s backhand returns—her signature weapon—were exposed by Se-young’s strategic placement of serves to the body. The Korean crowd, typically vocal for Shim, fell silent after the 10-3 mark, sensing the inevitability of the result.
Game 2 (21-3): If anything, Se-young played even more decisively. She varied her serve speed, mixing in flick serves that caught Shim off guard, and her footwork at the net was flawless. The final point came when Shim attempted a desperate drop shot, only for Se-young to intercept and smash down the line.
Reader handhold: For those unfamiliar with badminton scoring, each game is played to 21 points, and a player must win by at least a 2-point margin. The 21-3 scoreline is historically rare—only three such games have occurred in BWF Tour history.

What So for the Tournament and Beyond
Se-young’s dominance has immediate implications:
- Singapore Open Path: With this win, Se-young will next face either China’s Chen Yufei (world No. 2) or Indonesia’s Putri Sari (world No. 4) in the 16th round. A victory there would set up a potential quarterfinal clash with Tai Tzu-ying (world No. 3), who has beaten Se-young twice in 2026.
- World Rankings Impact: Se-young’s form ensures she’ll retain her No. 1 ranking through at least the next BWF World Tour update (June 10, 2026). Her 21-3 performance could earn her additional ranking points, potentially widening her lead over her rivals.
- Mental Edge: Shim’s defeat is a psychological blow to Korea’s women’s singles hopes. The two had split their last five meetings, but Shim’s collapse—losing the first game 21-3—will be scrutinized by her coaching team.
- Olympic Cycle Pressure: With the 2028 Los Angeles Olympics on the horizon, Se-young’s ability to dominate younger players like Shim (aged 22) while maintaining her peak suggests she could extend her prime into her mid-20s.
What’s Next for Se-young and the Singapore Open
Se-young’s next match is scheduled for May 28, 2026, at 19:00 local time (UTC+8) in the Singapore Open’s 16th round. The venue, the OCBC Arena, has hosted some of the most dramatic badminton moments in recent years, including Chen Long’s 2018 World Championships final victory.
