One of the most visible and discussed aspects of modern analytics is PITCHf/x data, whether it relates to pitcher tendencies, an umpire’s strike zone, or the hole in a batter’s swing. We carry plenty of PITCHf/x data on FanGraphs, but there are other sites that provide invaluable resources for analyzing the game through this lens.

To wit, we’ve updated our Library entry on PITCHf/x resources to include a couple of sites that weren’t around a few years ago when that page debuted. You’ll find links to Brooks Baseball, Texas Leaguers, Baseball Heatmaps, and Baseball Savant, in addition to a couple of nice primers from Mike Fast and Alan Nathan.

If you want to talk about PITCHf/x or ask related questions, drop a line in the comments, grab me on Twitter @NeilWeinberg44, or stop by our weekly Q&A chats Wednesdays at 3pm. Also, if you know of any resources we’re missing, please let us know.
