Baseball stats are the main component of sabermetrics, the objective analysis of baseball performance. The field is fraught with abbreviations and equations, so let’s start with the most basic batting stats: AB denotes the number of times per season a player is at bat, H records how often a batter reaches first base due to an uncaught hit, and R measures how often a player crosses home plate to score a run. Similarly, HR reflects total homeruns – a hit that allows the batter to circle all bases in one play.
