TripleS’s Yuyeon Brings Spark to the Mound: Traditional vs. Trendy First Pitch
On June 22, 2025, Yuyeon, a member of the K-pop girl group TripleS, took the mound at Jamsil Baseball Stadium in Seoul to throw the ceremonial first pitch for the KBO League game between the LG Twins and Doosan Bears. Ceremonial first pitches are a long-standing tradition in baseball, often performed by celebrities or public figures to excite the crowd and mark the start of the game.

Yuyeon's 'Slam Pitch' Makes Waves
Yuyeon didn't go with the traditional wind-up. Instead, she hurled the ball with flair in what's now being called a "slam pitch"—an energetic, almost theatrical throw that's stirring debate far beyond the third baseline. Her approach was original, eye-catching, and definitely broke the mold, making the atmosphere at the stadium both electric and light-hearted.
Supporters Say: Baseball Needs Fresh Air
Many fans welcomed her unique take. For starters, it caught the attention of younger audiences who might not otherwise tune into a KBO game. Idol stars like Yuyeon have the power to draw their massive fanbases into the sports world, expanding baseball’s reach and making it feel more inclusive.
Beyond demographics, the showy pitch added entertainment value. Sports are increasingly tied to pop culture in South Korea—and globally. The viral moment on social media turned Yuyeon’s 10-second pitch into a free marketing campaign for both KBO and TripleS. For comparison, U.S. singer Billie Eilish’s appearance on the mound at an MLB game created similar buzz, helping mainstream music and sports audiences meet in the middle.
Marketing teams dream of this kind of synergy (teamwork or combination). If baseball is to stay relevant amid streaming wars and esports explosions, moments like this might just be what the game needs.
Critics Say: Keep the Game Sacred
Still, traditional fans weren’t all smiles. In their view, the ceremonial first pitch should honor the game’s heritage—it’s not just a photo op. They argue that Yuyeon’s dramatic delivery undermined the seriousness and dignity of the ritual.
Adding to their frustration, the pitch didn’t quite go where it was supposed to. Untrained throws often lead to awkward or even dangerous outcomes, such as balls slipping or veering toward spectators or umpires, making fans feel uneasy.
Moreover, some fear that baseball could lose its identity if too much showbiz glitz takes over. While blending pop culture with athletics can boost attendance, detractors feel it risks turning the sport into spectacle.
Walking the Tightrope: Tradition vs. Tiktok
Yuyeon’s performance at Jamsil illustrates a cultural tension playing out in stadiums worldwide. Should first pitches be about charm and clicks—or about honoring the game?
There’s a middle ground. Celebrities can be briefed or trained ahead of time to ensure accurate, safe pitches. KBO can set guidelines that balance flair with form, giving room for personalized expression while preserving the ritual’s weight.
As fandoms evolve, so should traditions—but not by tossing the rulebook entirely. A potential fix might be offering dual moments: a formal first pitch followed by a “fun pitch” segment for entertainment value. This way neither audience feels disappointed.
Blending Bases: Final Thoughts
Yuyeon’s pitch sparked more than just online chatter—it reignited discussion about what baseball can and should be in the modern age. Like it or not, lines between sports and pop culture are vanishing. Whether it’s better for the long-term health of the game is still up for debate.
For now, it’s clear that traditions are bending—but not yet breaking. The real challenge lies in finding that perfect pitch between celebration and ceremony.
