Let me start here: Baseball Savant is just about the coolest publicly available tool on the internet for baseball fans right now. You can spend days deep diving into their databases, and they are regularly releasing more and more data: from OAA (Outs Above Average) to Barrels to xwOBA, you can find some sort of advanced metric for almost any aspect of baseball that, while not gospel truth, are really neat and take us closer and closer to the proprietary information and metrics that MLB clubs are using.
Today they dropped the coolest tool I’ve seen in quite some time: Statcast Swing Take.
