The 2026 World Baseball Classic is still a few months away, but the buzz is already building as players across Major League Baseball begin to declare their intentions to suit up for their respective countries. With 20 nations set to compete and a host of MLB talent expected to fill out the rosters, this edition of the WBC is shaping up to be another global showcase of elite baseball.

One intriguing name that’s surfaced in the early conversation? St.

Louis Cardinals top prospect JJ Wetherholt. While no Cardinals player has officially been announced for the tournament just yet, Wetherholt has made it clear he’s hoping to represent South Korea on the international stage.

“If I’m selected for the Korean national team at the 2026 WBC, I definitely want to play,” Wetherholt said recently.

Born in Baltimore, Wetherholt’s connection to Korea comes through his grandmother, who is South Korean. That familial tie could be enough to meet the eligibility requirements for the Korean roster, depending on how the team chooses to structure its selection process. Each WBC nation has its own criteria-some are strict about citizenship or residency, while others are more flexible with heritage-based qualifications.

And for South Korea, a team hungry to return to prominence after failing to advance past the first round since 2009, adding a high-upside MLB prospect like Wetherholt could be a meaningful boost. He brings athleticism, a polished approach at the plate, and a developing glove-tools that could fit nicely alongside a roster expected to feature a mix of KBO standouts and MLB-caliber talent.

Of course, there’s another layer to this: the timing. The World Baseball Classic kicks off March 5, right in the heart of MLB Spring Training. If Wetherholt does land on the Korean squad, he’d miss a significant chunk of time in Jupiter, Florida, where the Cardinals will be shaping their 2026 roster and preparing for the grind of the regular season.

That’s the kind of decision that can spark internal conversations within an organization. On one hand, there’s real value in a young player like Wetherholt getting reps against top-tier talent in a competitive environment. For hitters especially, the WBC offers far more meaningful at-bats than the typical early-March Spring Training game, where lineups are often filled with minor league hopefuls and back-end roster candidates.

On the other hand, there’s always a risk-particularly for pitchers-when players ramp up earlier than usual. We’ve seen it before: Adam Wainwright’s groin injury during the 2023 WBC cast a shadow over the start of his final MLB season. While that example doesn’t directly apply to Wetherholt, the broader concern about injury risk in high-intensity March games is real, especially for arms still building toward midseason form.

But Wetherholt is a position player, and the risk calculus changes there. For a young infielder still developing his game, the WBC could be a proving ground-an opportunity to face international veterans, adapt to different styles of play, and sharpen his skills under pressure. It’s a unique test that Spring Training just can’t replicate.

As of now, the Cardinals haven’t made any public comment on Wetherholt’s potential involvement, and historically, they’ve allowed players to make their own decisions regarding WBC participation. If the Korean national team extends the invitation, it’s hard to imagine St. Louis standing in the way.

For Wetherholt, this could be more than just a chance to represent his heritage-it could be a pivotal step in his journey to the majors. Competing on the world stage, under bright lights and against elite competition, might be exactly the kind of experience that accelerates his development and prepares him for what’s next in his MLB career.

And who knows? If he makes the roster and performs well, he could become a fan favorite not just in St. Louis, but in Seoul as well.
