My Take
Sumida's route into Nippon Professional Baseball is the kind I always root for. Ōmura in Nagasaki, then Hasami High School, then the Nishinippon Institute of Technology — no legendary baseball factory, no famous Tokyo university, just a steady regional climb that ends in a Saitama Seibu Lions uniform. At 177 cm he is not physically overwhelming by pitching standards either, which means he did not arrive here by intimidating anybody. Pitchers built that way usually have to think their way through a lineup instead of bullying it, and that is the version of the craft I enjoy watching most. His public file is still mostly blank: born in 1999, almost every field unfilled. But that is simply what an early career looks like on paper. The chapters worth reading have not been written yet, and I like being early.
