Tom Tango has toyed with the idea of player win-loss records for a while, and this past week he laid out a method on how to convert WPA into individual win-loss records. Tango challenged us to play around with this new toy with some of our favorite teams; the 2004 club popped to mind. The normal WPA caveats apply: there’s no accounting of fielding of defense or position, but this does perfectly add up to the team’s 105-57 record.
And the pitchers:
If you’re wondering about the negative values, Tango explains:
There are negative wins and negative losses. That happens when a pitcher pitches so poorly or so well, that he “breaks” the “sum of the parts equals the” theory we are constraining ourselves to. The reality is that trying to represent players in this way is a fudge to the way we really should be thinking it (WPA).
Naturally, Albert broke the system. This was a year when Jason Isringhausen was mostly just Izzy and not Baron Von Isringhausen. All hail the MV3.
The split between hitting/pitching+defense is pretty even 53-52. Anyway, next up I’ll probably look into the 1987 team, or maybe just last year’s team. Hopefully this proves to be semi-interesting. I like how it assigns a true W-L record for everyone that adds perfectly up to the team’s real W-L record, instead of just looking at a bunch of numbers and decimal points.
