## Your original baseball metric

When I was watching a game between the Reds and Nationals, won by the Reds on 15-0, I came up with below metric and am hoping it could be a really good one and there has not been a similar one in the past.

I would like to share it with you, and get a feedback from you.

Also let's exchange your original baseball metric here so someday someone like Bill James, Billy Beane or Michael Lewis could possibly find it!

-------------------------------------------

Most of current batting stats don’t consider the quality of a pitcher or the tightness of a game when a hit is produced, and as a result they put equal importance for a hit from best pitchers like Verlander or Darvish, or the one from decent pitchers who should be in the minor.

RBI is said to be one of batting stats that least reflects a batter’s actual ability to produce runs because it is largely dependent on a situation.

The value of each RBI should have a significant difference depending on which occasion those RBIs are earned. For example, one RBI earned on a 1-0 game should have a much bigger importance to a winning team than the one scored on a 10-0 game. RBI is the score that you simply add up all runs earned by a single player in a season, so it doesn’t give a consideration of the situation that each of those scores is produced.

I came up with a stat called RBI with CFW(Contribution for a Win) shown below, and it could resolve the problem by taking consideration of the differences in the situations.

RBI with CFW(10 points maximum that could be earned by a player in a single game)

=(10/Run difference in a game)*(Player's RBI in a game/Team's total RBI in a game)

(Situation 1)

On a 1-0 game, Player A scored sole RBI for a game won

RBI with CFW earned by player A

=(10/1-0)*(1/1)=10

So player A earned 10 RBI with CFW, which is the maximum that could be earned in a single game.

(Situation 2)

On a 10-5 game, Player A scored 2 RBIs, Player B scored 3, and Player C scored 5 for a game won

RBI with CFW earned by player A

=(10/10-5)*(2/10)=0.4

RBI with CFW earned by player B

=(10/10-5)*(3/10)=0.6

RBI with CFW earned by player C

=(10/10-5)*(5/10)=1

(Situation 3)

On a 10-9 game, Player A scored 2 RBIs, Player B scored 3, Player C scored 5 for a game won

RBI with CFW earned by player A

=(10/10-9)*(2/10)=2

RBI with CFW earned by player B

=(10/10-9)*(3/10)=3

RBI with CFW earned by player C

=(10/10-9)*(5/10)=5

There is one possible flow with this equation that it can be only applied to winning situations so it is possible that a good hitter can earn low RBI with CFW if he belongs to a bad team. But it is still useful when considering only games won and coming up with some kind of an average figure on a game by game basis.
