Statcast is amazing. The leaderboards are invaluable tools for anyone fascinated by baseball analytics. From a fantasy perspective, Statcast data is relatively untested compared to old mainstays, but the trove of data offers plenty of insight.
This piece focuses on Expected Weighted On-base Average (xwOBA), a stat that calculates what a player’s weighted-OBA should have been given his contact tendencies (or, inversely, a pitcher). Importantly, this is not designed to be a predictive tool. In order to make it predictive, one must find the difference between xwOBA and actual wOBA to find players who are under/over performing contact profile.
