I just think of pitchers as part of a team now, instead of single gunslingers. Avengers vs. Spider Man so to speak. Team based instead of single player. You can throw out an Opener if you want, that's the Rogue with sneak attack, and then you have Tank that takes most of the innings, and then you sprinkle in some other players, before going to the Wizard to end it with some fire power. I don't love the subjective stats in baseball as it is, but pitcher wins are already mostly meaningless and frequently subjective, so go for it. Assign the win to the pitcher who was "most pivotal". In a 10-1 blowout, that's going to be the bulk guy, but in a tight 2-1 game it might be the LOOGY that came in to a 2-out bases loaded situation and got the popup. Of course, a popup and a 400 foot home run steal are the same, it's never going to be perfect, but it's interesting. Hey I just thought myself into two post ideas. I wonder what how easy it is to query which pitcher was on the mound for the highest WPA event for each game.
