All-Time MLB First Base Range Factor Leaders
Career totals, every season from 1871–2026. Putouts plus assists per game at first base
Tom Jones is the all-time MLB leader in first base range factor with 11.20, 0.06 clear of George Stovall (11.14). He did it in 8 seasons, from 1902 to 1910. The top ten runs from 11.20 down to 10.69.
Career rate stats are limited to players with 1,000+ games at the position, the usual bar for all-time rate leaderboards. That is a raw total rather than a share of the schedule, so it falls unevenly across eras. Negro League seasons ran roughly 25 to 70 games against 154 or more in the American and National Leagues, and exactly one Negro League fielder reaches 1,000 games at a single position. The outfield is also one position here rather than three: the source splits left, centre and right into a file this site does not load, so an outfield board mixes the three corners together.
