My Take

I'll be honest, I came to Junzo Sekine knowing him more as a gentle, twinkly-eyed TV commentator than as a player, and then you dig in and realize this guy was the real deal, a genuine two-way talent who pitched and hit back when Japanese pro baseball was still finding its shape. Born in 1926, a Hosei man out of Sugamo, he basically grew up alongside the whole Showa era of the game, and you can feel that long arc in how he carried himself, no wasted motion, no ego, just a quiet competence that eventually carried him into the Hall of Fame. What I love is that he stayed warm and approachable to the very end, the kind of baseball elder you'd happily listen to for hours. When he passed in 2020, it really did feel like a whole gentle chapter of the sport closing.
