Here is my postseason award voting for 2017:
I have four rules:
1) Everything is about THIS season. It doesn’t matter what a guy did last year, that’s a different staory.
2) If two players are really close and one won a championship, go with the guy on the league championship.
3) No weight is given to age or potential unless a player is overwhelmingly superior but whose season value is low only because he missed playing time. This applies generally to rookies, but also applied to Shohei Otani last year.
4) The Best Nine Awards go to the most valuable player at each position. Whoever gets my MVP vote is automatically going to win a Best Nine Award. In the case of Otani last year, I gave Rule 3 precedence since he was easily the most productive pitcher and DH, but had slightly less total season value at each position than another player.
Here are my votes and a brief explanation of how I derive them.

The rationale behind my award votes
I base my votes on Bill James’ win share system, which – like all of us – has flaws, but also does one thing I like that WAR doesn’t: It only gives credit for actual games won. Players don’t accumulate wins by putting up numbers against a scale but by putting up numbers within the context of games won by a team within a league.
You start with wins, although I have to assign half a win for every tie because they are so common in Japan. I wish ties were worth half a win in the standings, since that would push the teams tying games closer to .500. NPB used to do it that way, but never mind.
Each team gets 3 shares for each win and 1.5 for each tie. So how do you distribute them? Step 1 is to estimate how many runs an average team in its league would score and allow given the parks each team plays in.
Let’s take the SoftBank Hawks. They won 94 games with no ties. That’s 3 * 94 = 282 win shares to be distributed among their players. The Hawks scored 638 runs, while allowing 483. The Hawks playing context is extremely unusual. The parks they played in in 2017 increased season home runs totals by 22 percent, while suppressing runs by 3 percent.
It’s not just Fukuoka Dome, though. It’s all the small and large parks the Hawks play in through the season. But the Hawks’ context makes them the PL team for which home runs are easiest to hit and runs are hardest to score.
The system uses that information to split the Hawks’ 282 win shares as follows: 136.94 for the hitters and 145.06 for the pitchers and fielders. The system then splits the pitchers and fielders based on things like double play and fielding efficiency, strikeouts, walks and so on.
This then gives SoftBank 102.28 win shares to be divided among the pitchers and 42.78 to be divied up among all the fielders. From that point we get into determine the relative claims of each player to those totals. All the hitters on a team are compared to each other and the win shares are distributed accordingly. The pitchers are a little more complicated because they require claim points for the higher leverage situations that middle relievers and closers encounter.
Fielders are even more complicated, and therein is one of brilliant elements of James’ system.
While modern measures (unavailable to the general public in Japan) can calculate an fielders’ efficiency, a good job can be done by estimating defensive quality by the players at each position for a given team by comparing each team’s results at a position to its league rivals with adjustments for the frequency of innings pitched by lefties (which increases ground ball opportunities for third basemen and shortstops) and ground balls.
If you adjust for the number of strikeouts a team gets, its totals for catcher put outs become relevant. The same goes for pitcher put outs, which influence the totals of assists by first basemen.
Each team’s postion totals are compared to the league norms. The positions on a team that exceed league norms will have more of the team’s fielding win shares to divide among the team’s players at that position.
In the case of the Hawks, the position breakdowns for win shares for 2017 are:
Catchers = 9.2 (No. 1 in Japan)
1st Base = 2.0 (5th)
2nd Base = 6.1 (1st)
3rd Base = 5.8 (1st)
Shortstop = 7.7 (5th)
Outfielders = 11.9 (3rd)
The Hawks team ends up looking like this after each player’s total is converted into an integer:

Kenta Imamiya 22 (14.8, 0 , 5.7)
