The ratio, according to Ron Shandler's publication, The Baseball Forecaster, that every pitcher regresses to is 10% HR/FB (though each batter has their own HR/FB ratio that they regress to, much like BABIP). Thus, a pitcher can only control their HR given up to the extent that they can strike out a lot of batters and limit the number of flyballs they give up. So perhaps it would be better to examine their flyball to batters faced ratio (the FB%, from my understanding, is based on BIP, not batters faced), as that would control their HR rate overall. Nice analysis overall. Diamond Mind's Tippett's analysis had explored how teams today need to be above average in the bullpen as well as other facets, in order to be successful and make the playoffs, so this is good stuff, as they seem to have stopped doing much analysis. In addition, Baseball Prospectus did a study for one of their books, analyzing success in the playoffs, and found that the strikeout rate for the pitching staff as a whole was one of the few factors important for success in the playoffs. Obviously, to do that, the bullpen also has to have a high strikeout rate and a number of playoff teams did show up on top. Interestingly, all are OUT of the playoffs (it is only a small factor, but still one of the few controllable factors a team has for maximizing success), except for the Rays and the Phillies didn't show up at all. The Phillies probably has the edge at closer, as WRXL, was another factor, and I would think that Lidge has a much better WRXL than Perceival. Last factor was team defense, and I have no idea which team is better. I, like everyone else, would be interested to see how our favorite team fared. Where on this site can I find it? Thanks for the good article.
