Let’s go back to the future

For lack of a better expression, this is a call to action.

If you live in Japan and have even the slightest interest in the history of the game, I would like you to join me in a quest to digitally document Japanese baseball history. Let’s get together and figure

Of course, we’d love to have play-by-play accounts of every game since the Japanese Baseball Federation revived pro baseball in 1936, but those kind of records  don’t exist in public. But Japan has libraries and collections of old newspapers, and together we can — game-by-game, season-by-season — uncover buried treasure.

Little by little, we can encode information about games, where were they played, who pitched, who played, what was the score, how many pitches were thrown? — Japanese papers have been publishing pitch counts since the 1960s!

I’ve always wondered how someone like Keishi Suzuki could throw huge numbers of innings and complete games from the age of 18 and keep doing it year after year until he finally slowed down a little at the age of 37 and then retired. The answer just might be out there.

Over the past 10 years or so, I’ve managed to compile a data base of seasonal data since 1946 for NPB’s pitchers, batters and fielders. Play-by-play data is freely available from 2006 thanks to the internet and I’ve been keeping records of various sorts since the mid-1990s. The detailed game data available to the media through BIS runs from 1970 to the present. Because we know how many runs are scored by a team in its main park(s), and how many home runs are hit in those games, we can make a good guess at park effects, but before 1970, that is going to take even more elbow grease

It’s funny how something can be in front of your face, and you never see it. After plowing through old game results and newspaper clippings from old papers for years at the Baseball Hall of Fame Library at Tokyo Dome, working on this or that project, it became obvious that charting Japan’s ocean of game history was beyond my reach. Yet, I hoped and thought that if I stuck at it, day after day, I could compile some kind of record of every pro game ever played How naive can one get?

Those days, from 1993 to 1997, I was writing my English language analytical guides to Japanese baseball and everything seemed possible. But upon becoming a full-time writer, that dream faded.

Then a funny thing happened. I decided to go to the baseball winter meetings a year ago in San Diego. Ira Stevens of Scout Dragon, my former collaborator on my guides, goes every year to market his product and asked me how come I didn’t check it out. It was a great idea and a great experience.

I filed a bunch of stories about Japanese players and teams, and met a number of people whose stuff I read. One of those, Rob Neyer, asked why I no longer had a website and why I didn’t try to start a Japanese version of Retrosheet. A website was the easy part. I came back and started this thing up. But a group, a network, organize? That’s not me…

That all changed today. I became attached to Bill James’ win shares because of the artful way it manages to handle fielding value, and having completed win shares for all the players in NPB from 1970-2015 today, I felt energized to tackle the basic park data needed to carry them back to 1936, so I put out a call for help on Twitter.

So if you are in Japan and can access a library to get the basic information from even one game, drop me a line and let’s work this out.

 

Japan’s MVPs over past 25 years

23-year-old Tetsuto Yamada’s 2015 season may have been Japan’s best over the past 25 years.

Having finally gotten around to calculating win shares in NPB from 1989 to 2015, I might as well use them to ask the question: How often are Japan’s MVP winners actually in the ballpark?

While every system, including WAR is going to catch some flak for its omissions and assumptions, Win Shares is a good match for Japan because a lot of data, particularly UZR for recent players, is not publicly available.

One win share is equivalent to a third of a win and what is really neat is that the win shares for pitchers correspond very well over a period of time with actual pitching wins. Of the 50 MVPs selected over the past 25 years, there have been 15 players selected who were, through this measure, vastly underqualified for the award. Of those 15, it should not surprise anyone who follows Japanese baseball that 12 were pitchers.

The most egregious selection since 1991 was left-hander Tsuyoshi Wada, the Pacific League’s 2010 MVP, whose 13 win shares were the fewest of any winner since then. The player with the most win shares that season (34) was the first shortstop to win a batting championship and a Golden Glove in the same season, Tsuyoshi Nishioka. Of the 50 actual MVPs, 31 either led their league in win shares or were within 3 win shares and have to be considered really good candidates. Since I first wrote this, I have extended my win shares calculations to 1970, and Wada’s MVP stands as NPB’s worst choice in 46 years.

If MVPs were decided by an objective estimate of contributions to wins and losses, who in the past 25 years would have won the most MVP awards? If you guessed Matsui, you would be correct. You can go with Hideki Matsui or Kazuo Matsui, both led their league in win shares five times. Hideki actually won two, while Kazuo won one.

Which player in Japan was most poorly represented in MVP awards? That title might go to Hirokazu Ibata during his heyday as the defensive leader of the Chunichi Dragons. Ibata led the Central League in win shares in 2004, ’07 and ’09, although he did so with fairly modest totals of 24, 24 and 26, respectively.

Who has had most valuable season over the past 25 years? One wouldn’t have to look far for that one. After a year in which he led the CL in seven offensive categories, including being the second player in NBP history to surpass the runner-up in runs scored by 30 or more (and the one not named Sadaharu Oh) , Yakult Swallows second baseman Tetsuto Yamada raked in 47 win shares in a 143-game season. Although the schedule has increased over this period from 130 games to as many as 146, Yamada’s 2015 season can arguably called the best in Japan in the last 25 years, narrowly beating out Ichiro Suzuki’s 1995 MVP season for the Orix BlueWave.

The other three in win shares per game top five are: No. 3 Yuki Yanagita 2015; No. 4 Ichiro Suzuki 1996 and No. 5 Tom O’Malley 1993. But O’Malley’s Hanshin Tigers finished fourth that season, and Atsuya Furuta, the catcher for the CL pennant-winning Swallows, was a fairly deserving winner with 32 win shares to O’Malley’s 34.

Here are the WS MVPs and actual MVPs in each league for the past five seasons with the win share totals of league leaders bolded and actual MVPs italicized:
