Tatsuro Hiroka played from 1954 to 1966 for the Giants, primarily at short stop. Frankly there's not much to say about this guy. He had a hell of a year as a rookie, but for his career he was offensively just sort of "meh". Given that he's in the hall of fame, I assume that he was a great defensive player, although defensive statistics for Japanese baseball in the 1950s either don't exist or I was unable to find them in a cursory internet search (or both). His one mark of real success for which documentation is available is as a manager. In 1976 Hiroka took over managing the Swallows and in two years they won the Japan Series. After leaving the Swallows he took over managing the Lions with whom he captured three pennants and two championships over four seasons. And then he was fired. Tough line of work. After leaving the Lions he moved into the front office, eventually becoming general manager of the Marines.
In some ways Hiroka reminds me of Dave Concepcion; they were both light-hitting shortstops for powerhouse teams. Of course there are ways in which the two are disanalogous too; Hiroka's career was quite short, and he missed he heart of the Giants' great runs. He won the Japan Series four times as a player (and lost it four other times), so obvious he played for a great team, but he retired just as the O-N Cannon was gearing up for its historic run in the late 60s and early 70s. Concepcion is not in the hall of fame. He has his supporters, but it's hard to imagine him even having an argument for the hall if he had played only 13 seasons. I suspect that Hiroka's induction was something of a life-time achievement award. He was a player on a successful team, he had a successful (if short) managing career, and then he became an executive. I'm not sure that I'd put someone in the hall of fame for that, but it sounds like a pretty good life in baseball.
