BPB stands for "base per ball." This baseball statistic measures the number of bases a batter gains per plate appearance, divided by the number of balls they see in the count. Synonyms for BPB include "bases per pitch" (BPP), "bases per strike" (BPS), and "bases per plate appearance" (BPA). These metrics can help baseball analysts evaluate a hitter's efficiency and consistency at the plate, and can provide insights into a team's offensive performance as a whole. As with any statistic, context is key, and other factors like on-base percentage and slugging percentage should also be considered when evaluating a player's overall contribution to the game.
