Cards & Stats
We use cool baseball cards to illuminate the history and illustrate the statistical analysis of Major League Baseball!
Having eventually tunneled over to BIP-ERA (what I’m calling the measure for balls-in-play runs allowed per game) by descending down the infamous “batting average for balls in play” (BABIP) rabbit hole,...
It’s kind of embarrassing to re-cover ground previously examined but the previous examining occurred with a much less advanced instrument for measuring the impact of pitchers’ “ball in play” (BIP) propensities....
Held off as long as I could on a “list.” Here’s top 50 all-time “ball in play” runs saved list as determined with the super-juiced multilevel model that is featured in latest...
In the last post, I adverted to the utility of standardizing runs in order to make sense of the contribution that “ball in play” (BIP) propensities have made to pitcher effectiveness over time. I want...
I’ve described in broad strokes the analytical strategy and the corresponding statistical model used to estimate BNIP-ERA and BIP-ERA. These are the two elements of pitching proficiency that correspond,...
So I’m going to try to tell you everything there is to know (in case you for some reason don’t want to just sit down and read the paper!) about this revamped system for measuring pitchers’ BIP propensities.
