Haruhiro Hamaguchi

Haruhiro Hamaguchi, born March 16, 1995, in Miyaki district, Saga Prefecture, is a pitcher currently with the Fukuoka SoftBank Hawks after starting his professional career with the Yokohama DeNA BayStars. He reached the pros through Kanagawa University rather than straight out of high school, and I think that route shapes a player. Four extra years of development, and four extra years of not being certain it would work out, tend to produce someone with a different relationship to the job than a teenage draftee has. The move between organizations adds another layer. Changing teams is unsettling, but plenty of pitchers only find their form after the change of scenery. At 173 cm he is not physically imposing by pitching standards, which matters far less than people assume — what plays on the mound has never been reducible to height. The interesting question now is how he carves out a role on a SoftBank roster that is deep almost everywhere. That is a harder problem than talent alone solves.
