Defensive Runs Saved

[caninatl04]

I did a bit of arithmetic to try to convert the change in defensive runs saved from last year (-25) to this year (+50). Using the Pythagorean wins share formula, I found:

 

Actual With 75
For 815 815
Against 788 863
  
Pythag 51.7% 47.1% 4.5%
Wins 83.7 76.4 7.4

 

Actual runs against were 788.  If they allowed 75 more runs against, their predicted win percentage would have fallen from 51.7% to 47.1% (4.5% fall) which translates into a 7.4 win differential.

I see what you did there.
