South Korea vs. Japan in WBC: Can Ryu Ji-hyun’s reinforced squad stun the MLB-heavy defending champs?

One of the most fascinating match-ups of the 2026 World Baseball Classic pits a veteran, domestically stocked South Korean side, under manager Ryu Ji-hyun, against a star-laden, MLB-stuffed Japanese line-up. While the rivalry will always be tinged with emotion, this matchup feels especially intriguing because of how different their construction and philosophy are.

Ryu's approach of leaning on KBO-tested depth while harvesting players of Korean descent from MLB has given him a more fortified roster that now appears ready to go toe-to-toe with some of the biggest juggernauts. Meanwhile, Japan heads to this tournament as the defending champions with arguably the most complete squad. The gap might look wide on paper, but Korea is convinced that discipline and unity can shrink the distance.

Ryu Ji-hyun builds a balanced and resilient Korean unit

Ryu Ji-hyun has whittled his squad down to a more rounded line-up, something Korea had been quite dependent on big names to deliver in previous tournaments. Focus has been on hard-contact hitters, multi-position defenders, and pitchers capable of grinding through close international contests. The squad is built around a core of experienced KBO veterans, whilst a couple of MLB-based Korean players provide additional quality.


The general game plan for Korea should hinge on fundamentals, base running, and pitching. Instead of matching Japan slug for slug, Ryu wants his group to shorten innings, create pressure, and force mistakes. The tone has to be set by the likes of Lee Jung-hoo and Kim Ha-seong, working the count at the plate and playing defense like their lives depend on it. It isn't the prettiest way to win, but it can be a potent weapon during tournament baseball.

Japan relies on MLB star power led by Shohei Ohtani

In stark contrast, Japan fields an intimidating roster stacked with recognizable names and experienced major leaguers. Looming over all else is two-way superstar Shohei Ohtani, whose mere presence alters the look of any match. He is backed by a talented group of pitchers and hitters who are accustomed to major North American competition.

It is this MLB-heavy core that gives Japan multiple paths to victory. With elite pitching, they can grind it out, using speed to manufacture runs; or with all that firepower, they can just hit their way by. Yet another significant benefit is their late-inning depth, as Japan has MLB-caliber high-velocity relievers available to finish up close games. If Korea has any chance at all, it is for its starters to keep games close, never let them get away by much, and not have all the drama cooked into the first couple of frames.
