Presented here is a virtual baseball card series that aims to serve as an introduction to sabermetrics: Why is on base percentage better than batting average? What’s a good OPS? What does wRC+ mean?
Our goal is to provide a basic understanding of the concepts behind the crazy acronyms as they become increasingly common in baseball coverage. Most entries consist of a brief description; a “range table” that breaks down what’s good, average, and bad; and top-five MLB leaderboards for the past two seasons.
