Masumi Hamachi

Masumi Hamachi was born in 1998 in Nishi-ku, Fukuoka, and pitches for the Yokohama DeNA BayStars in Nippon Professional Baseball. He stands 184 cm, which for a pitcher is a head start you cannot coach into somebody. What draws me to players like him is that pitching in NPB is a job with a brutal asymmetry built into it. You do not get to set your own rhythm the way a starter does, you often arrive in the innings where the game is already balanced on a knife edge, and the outings you handle cleanly vanish from the box score while the ones you don't get replayed all week. Nobody writes columns about a scoreless appearance in the seventh. I don't have a great deal of detail on him beyond the basics, and I'd rather say that plainly than invent color. But a kid from Fukuoka who made it to a professional mound and has stayed on one is already living a life almost nobody gets. That's enough of a story for me.
