Someone mentioned this in the game thread. I think ERA is and should be a pitching statistic, not pitching + fielding. While I agree with that, is there a stat for pitchers that combines ERA, pitcher errors and pitcher offensive output? I don't know how it would be done, but it could be interesting. If that doesn't make sense, I'm trying to ask if Pitcher A puts up a 4.00 era but hits 6 homeruns, is he more effective than Pitcher B that has a 3.75 era but no hits all season or Pitcher C with a 3.75 era but tons of errors? I don't know, I think it would be interesting and could be a nice way of measuring overall effectiveness as a baseball player, not necessarily as a pitcher. I think the problem with that is that by far the most important thing a pitcher does is pitch. Pitching is 80% or more of what a pitcher does while defense and offense make up the other 20%. A pitcher may have 3 or 4 ABs in a game at most and an average of 2 or 3 defensive chances per game, while he throws to probably 80+ pitches to 20+ batters. The difference in pitchers offensively and defensively is not going to make up much of any difference in them in pitching. Yes, I agree. Pitching may be even more than 80% importance. But if we're truly looking for who helps a team win -- and that should be the goal, not just who pitches better -- little things could make up a small difference in ERA. I just wonder how much pitcher offense/defense can make up for pitching. BP did a study about that recently. I can't remember the final tally, but someone with a bat like Marquis subtracted a significant number off his ERA.
