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 rate stats, generally a minimum of 3.1 Plate Appearances/Team Game (batting), 1.0 IP/Team Game (pitching), 0.67 Gm and Chances/Team Game (fielding), 0.2 SB att/Team Game (catchers), 0.1 SB att/Team Game (baserunners only since 1951), and 0.1 decision/Team Game (W-L%) is needed for single-season leaderboards. For pitcher fielding the minimums are reduced by a third. For LF, CF, RF fielding stats, we only have reliable data since 1898, so all leaders are since 1898. Explanation of min. requirements
