Hiromasa Saito

There's something genuinely compelling about a guy who follows the proper path — Toin Gakuen to Meiji University, one of the most respected baseball pipelines in Japan — and just quietly does the work. Hiromasa Saito, born in Edogawa, Tokyo, grew up in a city where there's a lot of noise, a lot of distraction, and he still made it through a brutally competitive amateur baseball system where thousands wash out before they ever turn pro. He went on to be Seibu's first-round pick in 2017, and honestly the guys who grind through college ball, who run hills in the offseason and fix their mechanics in the dark, are the backbone of the sport. His pro career was short, but getting there at all is worth respecting.
