Every few years, a young player comes along whose skill set is so unusual that scouts reach for the same comparison almost by reflex: the next Shohei Ohtani. It is a name that gets thrown around loosely in amateur baseball circles, attached to almost any two-way talent who can both pitch and hit at a respectable level. Most of the time, the comparison fades within a season or two, once professional competition sorts out which of a young player’s two skills is actually the one worth building a career around. But every so often, an organization decides the comparison is worth betting real money on — not just letting a prospect dabble at two positions in the low minors, but building an entire development plan around the idea that he might genuinely do both. That is exactly what the Texas Rangers have done with Kim Sung-joon, a Korean high school two-way player who signed with the organization for a $1.2 million bonus — about 1.68 billion Korean won — after graduating high school in January 2026. He pitches. He plays shortstop. And as of May 2026, in the Rangers’ Rookie league, he was already touching 156 kilometers per hour, or roughly 97 miles per hour, on the mound while still logging innings in the field.
The Next Ohtani?
In Korean baseball coverage, Kim Sung-joon has been given a nickname that carries enormous weight: “the Korean Ohtani.” It is not a label handed out casually. Shohei Ohtani has spent the better part of a decade redefining what is considered possible for a single professional baseball player, first in Japan’s Nippon Professional Baseball with the Nippon-Ham Fighters and then in MLB with the Los Angeles Angels and Los Angeles Dodgers, doing something no modern player had sustained at a high level — pitching as a frontline starter and hitting as an everyday middle-of-the-order threat, at the same time, for years on end. That combination used to be considered a novelty reserved for youth baseball and college ball, something every player eventually gives up in favor of specializing in whichever skill projects better professionally. Ohtani never gave it up, and in doing so he turned “two-way player” from a developmental phase into a legitimate, marketable, roster-altering category of major league talent.
Kim Sung-joon’s game has been explicitly modeled on that template. In Korean high school baseball, he built his reputation the same way Ohtani did as an amateur in Japan — pitching in critical innings and also holding down a key defensive position, in Kim’s case shortstop, one of the most demanding spots on the diamond both physically and mentally. A player who can start at shortstop and also take the mound as a legitimate pitching prospect is rare enough on its own; a player who can do both well enough that a major league organization is willing to pay a seven-figure bonus and design a bespoke development track around preserving that duality is rarer still. That is the profile that earned Kim the “Korean Ohtani” nickname in Korean sports media outlets like MK Sports, Xports News, and Nate Sports well before he ever set foot on a professional field in the United States.
It’s worth being precise about what the nickname does and does not claim. Nobody is suggesting Kim Sung-joon has already accomplished anything close to what Ohtani has accomplished in NPB and MLB — he is an 18-year-old professional in his first year out of high school, still working through the lower levels of a minor league system. The comparison is about approach and archetype, not achievement: a young player being developed, on purpose, as a genuine two-way talent, by an organization that has decided the bet is worth making rather than forcing an early specialization decision. Whether Kim ultimately becomes a full-time pitcher, a full-time position player, or something closer to Ohtani’s rare dual-threat model is a question that will play out over years, not months. But the fact that a major league franchise is willing to structure a prospect’s entire early development around keeping that question open is itself the story.
A $1.2 Million Bet
The financial commitment behind this signing is significant, and it says a lot about how seriously the Rangers view Kim Sung-joon’s upside. According to Korean reporting from outlets including MK Sports, MoneyToday, and Daum, Kim signed with Texas for a bonus of $1.2 million, or approximately 1.68 billion Korean won. For context, international amateur signings out of markets like Korea, Japan, and Latin America vary enormously in bonus size depending on age, projected ceiling, and how many teams are competing for a player’s signature. A bonus in the seven-figure range signals that Texas viewed Kim not as a speculative flier or a low-cost lottery ticket, but as a legitimate difference-making prospect worth a real financial commitment — the kind of number typically reserved for premium talent, not for a player the organization expects to wash out of the system within a year or two.
The timeline matters here too. Kim officially joined the Rangers organization after graduating high school in January 2026, which is the standard pathway for a Korean amateur player signing directly with an MLB club rather than entering the KBO draft. That decision — bypassing Korean professional baseball to sign internationally as an amateur — is itself a notable one, and it lines up with the broader arc of the Ohtani comparison. Ohtani, for his part, built his early two-way reputation in Japan’s NPB before eventually moving to MLB years later as an established star. Kim Sung-joon is taking a different route, entering an MLB player-development system directly out of high school, with his two-way projection intact from day one rather than something he’ll have to prove or re-establish after already becoming known as a specialist in another league first.
For the Rangers, signing a player like this isn’t just about adding one interesting name to a farm system depth chart. It’s a statement about scouting philosophy. Teams that spend real bonus money on unconventional prospects — two-way players, converted position players, players with unusual physical tools that don’t fit a standard mold — are making a bet that the traditional, narrower way of projecting amateur talent leaves value on the table. Kim Sung-joon represents exactly that kind of bet: a player whose value proposition only makes sense if you’re willing to imagine two different career outcomes running in parallel, rather than forcing him to pick a lane before he has even played a single professional inning.
Building a Two-Way Program
Signing a two-way prospect is one thing. Actually developing him as one, without quietly nudging him toward a single position the way most organizations do with dual-threat amateurs, is a much harder commitment to follow through on — and it’s here that the Rangers have made their clearest statement of intent. According to Korean coverage, Texas has built Kim Sung-joon a customized two-way development program, modeled explicitly on the same pitcher/hitter dual-training approach that Shohei Ohtani used earlier in his own career with Japan’s Nippon-Ham Fighters in NPB.
That detail is the most important piece of this entire story, because it tells you the Rangers aren’t simply letting Kim keep pitching and playing shortstop until the organization eventually forces a decision — a common, almost default outcome for two-way amateur prospects once they hit full-season professional baseball, where workload management, roster construction, and coaching bandwidth all push toward specialization. Instead, Texas appears to be borrowing directly from the actual blueprint that made Ohtani’s dual-threat career sustainable in the first place: a structured throwing and hitting program designed around managing fatigue and injury risk across two disciplines at once, rather than treating pitching and hitting development as competing priorities that inevitably squeeze each other out.
The Nippon-Ham Fighters’ approach to Ohtani during his NPB years is now something of a case study in professional baseball development circles — carefully sequencing throwing days, at-bats, and rest so that neither skill set was chronically shortchanged, and treating the two-way plan as a long-term organizational commitment rather than a short-term experiment to be abandoned at the first sign of strain. For a major league organization to explicitly model a new signee’s program on that same approach is a meaningful signal. It suggests the Rangers see enough plate discipline, arm strength, and defensive actions in Kim Sung-joon to justify the extra logistical complexity of building parallel throwing and hitting tracks for a teenager rather than simplifying his path early.
It also raises the stakes on how his early results get read. A conventional pitching prospect who has a strong Rookie league start gets evaluated purely on pitching indicators — velocity, command, secondary pitches. A conventional infield prospect gets evaluated on hitting and defensive indicators. Kim Sung-joon is being evaluated, deliberately, on both tracks simultaneously, which means his development timeline is likely to look different — and potentially slower in terms of innings or at-bats accumulated on either side individually — than a single-discipline prospect at the same stage. That’s the trade-off the Rangers have knowingly made in exchange for keeping the full range of his upside on the table.
Early Returns in the Rookie League
The first real data point on how that bet is paying off came in May 2026, a few months after Kim officially joined the organization. According to Korean reporting from Xports News and Nate Sports, Kim Sung-joon was pitching in the Rangers’ Rookie league by that point and had already thrown a fastball as fast as 156 kilometers per hour — approximately 97 miles per hour. That is a notable number for any young pitcher at that level, let alone one who is splitting development time with shortstop rather than devoting all of his throwing program to pitching alone. A fastball touching the upper 90s in miles per hour typically places a prospect’s arm strength firmly in the category scouts pay close attention to, regardless of what else that player might be doing on defense.
Just as notably, Kim wasn’t only pitching. As of that May 2026 update, he was also playing shortstop in the Rookie league, meaning the two-way program wasn’t a plan on paper that had quietly narrowed once real games started — he was actually appearing in both roles, in-season, at the level Texas had assigned him to. Korean coverage described him as having been promoted within his first year due to his performance, which — while the specific level and assignment details beyond “Rookie league as of May 2026” aren’t part of the confirmed reporting — at minimum indicates the early returns on both sides of his game were strong enough for the organization to move him forward rather than hold him back or narrow his role.
It’s worth being careful about what conclusions can fairly be drawn from a single reported velocity figure and a Rookie league assignment. Rookie ball is, by design, an early developmental level, and performance there — however encouraging — is not a reliable predictor of how a player will perform against advancing levels of competition over a multi-year development arc. What the 156 km/h fastball and the continued shortstop reps do confirm is that, several months into the Rangers’ customized two-way program, neither half of Kim Sung-joon’s game had been quietly shelved. Both were still actively part of his in-game workload, which is itself the clearest early evidence that the organization’s stated commitment to developing him as a genuine two-way player was being followed through on the field, not just described in a press release.
Why MLB Is Chasing the Next Ohtani
For American readers, the broader context here needs almost no translation. The Texas Rangers are a well-known, well-established MLB franchise, and the “next Ohtani” comparison is one of the most immediately meaningful shorthand phrases in the sport right now — Shohei Ohtani’s two-way ability, and the way it has reshaped conversations about roster construction, contract value, and what a single player can realistically be worth to a franchise, has made “the next Ohtani” a phrase every baseball fan understands instantly, even if they’ve never followed Korean amateur baseball a day in their life.
What makes the Kim Sung-joon signing worth paying attention to isn’t just that one team found one interesting prospect. It’s a visible data point in a larger pattern: major league organizations are now actively scouting and signing Korean two-way amateur talent specifically because of what Ohtani has proven is possible. Before Ohtani’s sustained MLB success, a team investing a seven-figure bonus and a custom dual-discipline development program in an amateur two-way player would have been a much harder sell internally — the conventional wisdom for decades favored quickly identifying which skill was more valuable and building a development plan around that skill alone, treating the other as a bonus tool at best. Ohtani didn’t just individually defy that logic; he made it commercially and competitively rational for front offices to bet on the model itself, for the right player. Kim Sung-joon signing with Texas, and Texas responding by building him a program explicitly modeled on Ohtani’s own NPB development path, is exactly what that shift in scouting philosophy looks like in practice — not a one-off curiosity, but a franchise applying a now-proven blueprint to a new prospect they believe has the tools to justify it.
That’s also why this story sits differently than a typical “promising international signee” piece. Most amateur international signings, even well-regarded ones, are single-track bets — a team likes a hitter’s bat, or a pitcher’s arm, and commits resources accordingly. The decision to build Kim Sung-joon a genuinely dual-track program is a bet on a specific, rare archetype that until recently had almost no successful modern precedent to point to. Now it has one of the most famous precedents in the sport’s history, and that changes the calculus for how aggressively a team like Texas is willing to pursue and develop the next player who looks like he might fit the mold.
What We Don’t Know Yet
It’s worth being clear-eyed about the limits of what’s confirmed at this stage. Kim Sung-joon’s exact assignment or promotion level beyond “Rookie league as of May 2026” isn’t part of the verified reporting behind this story, nor are additional statistics beyond the 156 km/h fastball figure — no season-long ERA, batting average, innings totals, or at-bat counts have been confirmed in the Korean coverage reviewed for this piece, and none of that should be assumed or estimated. The specifics of his contract beyond the bonus figure, his exact high school background, and any additional velocity or hitting data beyond what’s been reported here also remain unconfirmed.
What is confirmed, and what makes this worth following, is narrower and clearer: an 18-year-old Korean two-way amateur, nicknamed “the Korean Ohtani” for a reason, signed with the Texas Rangers for a $1.2 million bonus after his January 2026 high school graduation; the Rangers responded by building him a customized two-way development program modeled on Ohtani’s own NPB training approach; and by May 2026, in the Rookie league, he was already pitching in the mid-150s kilometers per hour while continuing to play shortstop. That is a real, meaningful start to a two-way development story — not proof of anything beyond that.
What Comes Next
The next real test for Kim Sung-joon’s two-way path will be the same test every two-way prospect eventually faces: what happens as the level of competition rises and the workload demands of both pitching and playing an everyday defensive position start to genuinely compete for his time, his throwing arm, and his development bandwidth. Ohtani’s own NPB and MLB career shows that model can work at the highest level — but it also shows how much organizational discipline and individualized planning it takes to keep it working, year after year, without one half of the game quietly winning out over the other by default.
For now, the Rangers appear committed to giving Kim Sung-joon the same kind of runway that made Ohtani’s dual-threat career possible in the first place, rather than forcing an early specialization decision most organizations would have already made. Whether that commitment holds as he climbs through the minor league system — and whether his performance on both sides of the ball justifies it — will be the story to watch in the years ahead. For a franchise and a fan base that has seen how transformative one true two-way player can be for a roster, the early signs out of Rookie ball in May 2026 were enough to keep the bet very much alive.

Frequently Asked Questions
Who is Kim Sung-joon?
Kim Sung-joon is a Korean high school two-way baseball player — meaning he both pitches and plays a key defensive position, shortstop — who has been nicknamed “the Korean Ohtani” in Korean sports media because his dual-threat skill set is explicitly modeled on Shohei Ohtani’s two-way approach. He signed with the Texas Rangers for a $1.2 million bonus after graduating high school in January 2026, and by May 2026 was already pitching and playing shortstop in the Rangers’ Rookie league.
Why is he compared to Shohei Ohtani specifically?
The comparison is about archetype and approach rather than accomplishment. Shohei Ohtani proved, first in Japan’s NPB with the Nippon-Ham Fighters and later in MLB, that a player can sustain being a frontline pitcher and an everyday hitter at the same time over a long professional career — a combination most modern baseball organizations previously treated as unsustainable past the amateur level. Kim Sung-joon is being developed on that same dual-track model, with the Texas Rangers explicitly building his program around the same pitcher/hitter training approach Ohtani used early in his own career. The nickname reflects that shared developmental philosophy, not a claim that Kim has already matched Ohtani’s results.
How fast does Kim Sung-joon throw?
As of May 2026, in the Texas Rangers’ Rookie league, Kim Sung-joon had thrown a fastball up to 156 kilometers per hour, which converts to approximately 97 miles per hour. That is a notable velocity figure for a young pitcher at that developmental level, particularly one who is also splitting his throwing and training time with shortstop rather than focusing exclusively on pitching.
Is Texas actually developing him as both a pitcher and a position player, or will he eventually specialize?
As of the reporting behind this story, the Rangers have built Kim Sung-joon a customized two-way development program rather than steering him toward one discipline early, and as of May 2026 he was still actively playing both shortstop and pitcher in the Rookie league. Whether that dual-track path continues as he advances through the minor league system — the same challenge every two-way prospect eventually faces — isn’t yet confirmed one way or the other, and nothing beyond his Rookie league assignment and the 156 km/h fastball figure has been verified for this piece.
