1871 MLB Season Leaders

Every ranking on this page is worked out inside one league. 1871 is counted as a single league, Other leagues, and a player is ranked only against the men in his own. Leading the American League and leading baseball are different claims, and the one we can make from these files is the first. There is no combined table anywhere on this page, because adding two leagues together would produce a number that no record book recognises.

There are 23 ranking tables here, 15 places deep. Players tied on a value share a place, so a table can run past ten rows when the tenth spot is shared, and a league with fewer than ten qualified players in a category is left out rather than shown as a top ten that is not one. A player who did none of the thing is not ranked in it either — a shutout table lists the pitchers who threw one, not the hundreds who threw none tied on zero. Some categories are missing on purpose: nobody leads a league in strikeouts at the plate, in losses, or in home runs allowed. A ranking is meant to mark an achievement, so only achievements are ranked.

Wins above replacement on this page is ours, not the source database's. The hitting and pitching files carry a WAR column that we compute here from the same season lines you see, using park factors and a run environment worked out per season. Published versions elsewhere use different methods and will not match ours exactly. Every other column is the record as the database supplies it.

Names on this page lead to that player's own record. Most of them open a full career page with every season he appeared in. Some open a summary screen instead — we pre-build pages for the players people look for, and everyone else is assembled on demand from the same files, so the numbers are identical either way even though the address looks different.
