I've been looking at our run differentials and decided to break them down a bit. This may or may not be valid but that can be discussed also.
First of all, here is the methodology I used. The Yankees had a run differential of +210 and the Jays were -18 so their total difference is 228. The offensive difference in runs scored between the Yankees and Jays is 124 runs. This leaves 104 runs (228-124) to account for in fielding + defense. The Yankees Fangraphs Fld is +23.2 while the Jays is -16.0 for a difference of 39.2 runs. The pitching difference is then 104 - 39.2 = 64.8 runs.
In summary the 228 run difference can be broken down into:
- Offense , 124 runs , 54.4%
- Pitching , 64.8 runs , 28.4%
- Defense , 39.2 runs , 17.2%
I did the same thing for the Rays:
- Offense , -36 runs , -32.4%
- Pitching , 76.3 runs , 68.7%
- Defense , 54.7 runs , 63.7%
And the Red Sox:
- Offense , 132 runs , 84.6%
- Pitching , -34.8 runs , -22.3%
- Defense , 58.8 runs , 37.7%
Overall there is a 495 run combined difference for the 3 teams:
- Offense , 220 runs , 44.4%
- Pitching , 106.3 runs , 21.5%
- Defense , 168.7 runs , 34.1%
Once again, I'm not sure about the validity of doing it this way but you can discuss that too. Hopefully there are no math errors though.
