OPS: Begone! Part 2
May 27, 2003 - Jason
I'm confused with the players of different batting average as I read the results it looks like the players more dependent on secondary skills produce more runs per OPS than a player who relies on batting average? I was under the impression that batting average players were a bit better than walk slugging types.

Are you sure the batting average thing isn't context dependent i.e. depending on the run environment?
How are Runs Really Created

While I admire the academic desire to design the perfect theoritical evaluation tools, I find it a bit dishonest to harp to the point of obsession on things that happen to work well. Newtonian Physics has been shown to be fundamentally unsound for almost 100 years and yet it is still heavily used becuase it works so well. Until their are 3 or 4 Barry Bonds on a team I don't see the particular need to be so detailed. OK, so I lied I do see one use. Evaluating relief pitchers. I think it's great that the Prospectus guys have run with a system that credits guys for the work they do based on when the enter the game, but I'd still ike to see a system that accounts for the actual skill of the batters faced. There's a big difference between coming in with the bases loaded and the 8 hitter up vs. having to pitch to Bonds or Sosa in that situation.

tango I think your crude Bonds analysis goofed up in exactly the types of ways you intended to prevent with your article. On a small scale the answer was more or less answered about having a skewed lineup kind of. The problems I see are that as you so elegantly noted walks are valuable only because others drive you in. By using just OBA you missed that completely as most of Bonds exceptional value is in the walks. While the Giants biggest weakness has been driving him in. Similarily, and I know your going to kick yourself for this one, but if the other 8 guys in the order are all the same, how would you get any difference in production aside from lineup effects, the run environment "Bonds" hit in was the same no matter what. On the other hand think ofthe drastic difference in run environment between those players who hit in front of Barry and those who don't? It would be interesting to analyze all of the line-ups that have been tried to see which would be the most effective based on the run environment concept, and of course see if you could find a better one.

Quick question is LI biased against good relievers on bad teams? I can see that on worse teams and exceedingly good teams a larger percentage of the outs available to the pen will be of the high leverage variety and I'm wondering how that impacts the stat?
