The analytically minded baseball fan knows all about BABIP. BABIP is essentially a sabermetric disclaimer. It’s something we cite every time we observe something new or different in a player’s game. “It seems like Player X is getting better (or worse), but it might just be BABIP noise.” In a way, HR/FB is a lot like that, especially for pitchers.
Pitchers can dramatically improve their run prevention with a little good fortune in the HR/FB department, even if they’re not really doing much differently. To that end, we’ve updated our HR/FB Library entry to help you better understand how to use the statistic to evaluate pitchers and their runs of good and bad performance.
