Single-Season Leaders & Records for Range Factor/9Inn as LF (s.1954)

Baseball Leaders & Baseball Records: Single-Season Career Active Progressive Year-by-Year Top-Tens Yearly League

+ - Indicates Hall of Famer. Bold indicates active player.

Statistic Description: Range Factor per 9 Inn 9 * (Putouts + Assists) / Innings Played

Only players who finished in the top 40 for the majors in a season will appear on this list.
Leaders from the current season are only included for rate stats after July 1st.

For batting rate stats, generally a minimum of 3.1 Plate Appearances/G, 1.0 IP/G, 0.5 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 1954, so all leaders are since 1954. Explanation of min. requirements

This statistic is computed from play-by-play data which is only complete from 1974 to the present. From 1948-1973, the data is incomplete, though for most seasons only less than 20 games per season total are missing. Please see our page on data coverage for a full view of the data used to create these lists.
