How the 2003 leaderboards are built

Batters qualify at PA >= 3.1 x their league's scheduled games that season (the batting-title rule shape, applied era-consistently; 3.1 x 162 = 502 in the modern schedule). Pitchers qualify on the W, ERA, SO and ERA+ boards at IP >= their league's scheduled games that season (1 inning per scheduled team game; 162 in the modern schedule). The saves board uses the reliever bar: IP >= one-third of scheduled games.

Adjusted stats use same-league-season normalization only: OPS+ = 100 x (OBP/lgOBP + SLG/lgSLG - 1) and ERA+ = 100 x league ERA / player ERA, computed within each player's own league that season. They are not park-adjusted and are not the full Baseball-Reference formulas. In the combined all-leagues view, adjusted values keep their own-league normalization. Unrecorded early-era stats are never invented; a board simply does not appear for a stat the source did not record that season.

Season records come from the SABR / Sean Lahman baseball database (2025 edition), used under Creative Commons Attribution-ShareAlike 3.0. Full credits live on our sources page.
