Shotaro Morii’s dual mandate takes shape as A’s three-way prospect finds his rhythm

SAN JOSE, Calif. - Shotaro Morii has been known for his ambitions long before he stepped on a minor league diamond in the United States. Now, the 19-year-old Athletics prospect is showing that the plan is more than a headline. In the Bay Area in late May, Morii arrived for work with his mind half on baseball, half on the everyday adjustments of life stateside. After a lift, he and teammate Itsuki Takemoto shared laughter so loud it carried into the field, a small but telling moment that reflects how quickly Morii is becoming comfortable with his new teammates and routines. “I love him,” Morii said of Takemoto, describing how the roommate jokes often circle back to baseball talk and day-to-day guidance.

Morii’s attention comes from a rare profile in modern pro baseball. The Athletics are building him as a three-way player, an uncommon combination of hitter, pitcher, and infield defender. He is not trying to replicate the exact path of Shohei Ohtani, but like Ohtani’s story, Morii’s pitch-and-bat concept is driven by a belief that development can be more creative than traditional specialization. Morii also skipped the draft back in Japan to pursue this route in the U.S., and he has treated the workload as both a challenge and a promise, saying he is happy to be pitching and hitting in the same stretch of time.

Comfort, however, is not only measured by relationships. Morii’s English skills have become part of his on-field growth. He has pushed to reduce his reliance on an interpreter, and his communication style is improving enough that he can handle media questions in English during spring coverage. The adjustment was never just vocabulary. Morii also changed his approach to practice and preparation. In a separate spring update, reported that Morii has leaned on daily language practice tools, including conversational help from an artificial intelligence app, to speed up learning while he remains focused on the rhythms of baseball.

The Athletics’ farm plan puts structure around the ambition. Morii, once signed as a shortstop, has been shifted to second base so he can keep both sides of his game on track without overtaxing his arm. In Stockton, the idea is to keep him active at the plate three or four times per week, sometimes as a hitter and sometimes at designated hitter, while also progressing his pitching role. According to the AP report, pitching is scheduled for Thursdays, beginning with a cautious, one-inning “opener” plan in his first appearances. The expectation is to build gradually from there, a workload philosophy aimed at keeping his body available rather than rushing his endurance.

Injuries and adaptation have shaped the timeline. Morii injured his right hamstring during March’s MLB Spring Breakout in Arizona and spent close to two months rehabbing at the A’s facility in Mesa. The report said he even adjusted his running mechanics to reduce long-term risk, including shortening his stride with guidance from training staff. Those changes matter because Morii’s identity in the organization depends on staying on the field in three separate roles. The hamstring is also why the Athletics’ approach emphasizes “quality” reps over sheer volume, especially with Morii coming from a background where taking hundreds of swings per day is normal.

So far, the stat line shows both the promise and the growing pains of a player learning multiple roles at once. With the Stockton Ports, Morii entered the AP story with a 0-2 record and a 10.50 ERA across five pitching outings totaling six innings. Offensively, he was batting.174 with two doubles, a triple, four RBIs, and two stolen bases. The numbers do not define him, but they do frame what comes next: deeper pitching outings, more consistent hitting timing, and continued confidence at second base as his hamstring recovery holds.

For context, even players who have tried “everything” in their amateur or college careers view Morii’s challenge as different, because the work happens simultaneously, not sequentially. The AP report highlighted that Casey Schmitt, a former multi-position college player, sees Morii doing it at a younger age and higher in the system than many who took similar routes. For the Athletics, this is not just about one prospect’s versatility. It is about testing whether a three-way development model can be sustainable in the minor leagues, and whether it can produce a player who can handle the grind when the roles get even heavier at higher levels.
