Historic career value for all NPB players

Here is a sample of what’s coming to jballallen.com. I am currently in the process of transforming the site’s data content to include user-searchable data tables for your reference, with much of it available only here.

The table below allows you to search for players career value for all players in Nippon Professional Baseball, including its predecessor the Japan Baseball League, as calculated using Bill James’ Win Shares.

For the uninitiated, three win shares is equivalent to one team win. The system has its detractors and has its shortcomings as does the more popular wins above replacement, but I’ll leave that for another space.

Win Shares’ flaws are largely artifacts created by the small sample sizes of fluke seasons and are mitigated to some degree when one is looking at careers.

As a teaser, here are the career value leaders for play within NPB by position:

*–The career value leader for players who spent most of their careers at second base is Kazuyoshi Tatsunami, with 315.2, followed by Hideto Asamura at 310.3, but neither played more than 1,300 games at second. I picked Chiba based on his overwhelming defensive superiority at second in his 1,415 games. Morimichi Takagi (294.6) was fourth overall despite playing over 2,000 games at second.

Of course, these valuations don’t reflect any part of the careers spent in America… For the full searchable table, read on.

Japan loses one of its greats

— apologies: this post was supposed to go out Tuesday night along with a database table showing the top shortstops in Japanese pro baseball history, but my relationship with my database table software is not a happy one, and that is still working…

Hall of Famer Yoshio Yoshida died Monday, Feb. 3 of a cerebral infarction, multiple media outlets reported Tuesday. Yoshida is the only man to manage the Hanshin Tigers three times, with his second stint producing the 1985 Japan Series championships, the Tigers first and only one until 2023.

Because most of us only remember him as the Tigers manager, it is easy to understand why most of Tuesday’s headlines lead with Hanshin’s Japan Series triumph, which at the time was a huge deal.

After all, of the 12 franchises to play 5,000 or more games, the Tigers’ winning percentage since league play began in 1936 is .517, fourth best after the Giants, the Hawks and the 1950 expansion Lions.

Yet, in 1984, the Giants had won 17 Japan Series, the Lions five, the Hawks three and the Tigers none. At that time, the Kintetsu Buffaloes where the only other remaining NPB franchise without a Japan Series title.

So it is easy to see how the one championship thrust Yoshida into the spotlight in 1985, although he was managing skills were frequently criticized by his players.

But because of the Japan Series title, it is easy to overlook the fact that Yoshida was one of the greatest shortstops Japan has ever produced. He burst onto the scene in 1953, when he set a Central League record for double plays by a shortstop with 94, a mark that would stand for 28 years — that’s longer than Babe Ruth’s single season home run record lasted.

The data that was supposed to go here would show that of all the shortstops with 1,000 or more games played, only three created more defensive value per game — as measured by Bill James’ Win Shares.”

The top 10 in win shares per 100 career games (with one win equal to three win shares):
