A ** by the stat's value indicates the player had fewer than the required number of at bats or plate appearances for the BA, OBP, SLG or OPS title that year. In order to rank the player, the necessary number of hitless at bats were added to the player's season total. The value printed here is their actual value and not the value used to rank them, therefore some numbers may appear out of order.

For batting rate stats, generally a minimum of 3.1 Plate Appearances/G, 1.0 IP/G, 0.67 Gm and Chances/Team Game (fielding), 0.2 SB att/Team Game (catchers), and 0.1 SB att/Team Game (baserunners only since 1951), and 0.1 decision/G for single-season leaderboards generally needed for rate statistics. For pitcher fielding the minimums are reduced by a third. For LF, CF, RF fielding stats, we only have reliable data since 1901, so all leaders are since 1901. Explanation of min. requirements
