Pitching and Fielding, Part Four
February 06, 2004
In which I uncover a mistake.
I’ve been preparing an article that compares the relative outcomes of the three systems for splitting defensive Win Shares between pitching and fielding. As a result of comparing my proposed system with the original James version, and the Charlie Saeger version, I realized that some of my formulas were “overcorrecting.”
I won’t get into the math right now, but suffice to say that I was essentially double-counting my adjustments for errors, double plays, outfield assists and passed balls. So I’ve run the numbers again, and I have attached a new table comparing the three systems.
Once again, I’ve highlighted the teams that seem to vary the most, and I’ll follow up over the weekend with a summary of the differences between our systems.
