Part two on the debate between traditional statistics and sabermetrics.
Note: While I was typing this up, I had some inspiration on some additional posts that could be included in this series. Therefore, you may notice that I have changed the header at the top to reflect that this series will have an indefinite number of posts. The same has been done for the ERA/FIP Fistfight post. Also, I’m going to keep the whole series available at all times on the right of this page, under the title “The Statistics Debate Series.” I honestly feel that this series is one of the most interesting pieces that I’ve written since I created this blog.
Well I’ve been mulling this over for several weeks now. I posted a while back the first part of this series, which involved a disagreement over whether ERA or FIP was more useful in judging a pitcher’s worth. I used an extreme example of an infinitely large ballpark and a perfect defense versus a completely average ballpark and defense to show that FIP was a better predictor of a pitcher’s future ERA. However, an infinitely large field with a perfect defense doesn’t exist, so it’s arguable that my example only holds true in this single case (a point that many of my math teachers enjoy telling me when I try to write out some proofs), but I’ll save my talk about FIP and ERA for later.

Recently, there were rumors swirling around that the Twins were interested in signing either of these two to play either 2nd or 3rd base. Fortunately, they won’t get that chance now, thanks to Giants GM Brian Sabean.
