In case it’s not obvious, you can tell a lot more about a hitter from one year of data than you can about a pitcher. All this data is from research that Pizza Cutter conducted, which can be found in the links below. If a statistic is not included, the means it did not stabilize over the intervals that Pizza Cutter tested (which was up to 750 PA / BF).
PA = Plate Appearance, BF = Batters Faced
