What is RBI in Baseball?
Runs Batted In · Batting
RBI, or Runs Batted In, credits a batter each time their at-bat directly results in a run scoring. A player earns an RBI on a hit, sacrifice fly, walk with the bases loaded, or a fielder's choice that scores a runner. RBI does not include runs scored due to errors.
Formula
RBI = Runs scored due to batter's plate appearance (no errors)
If a runner on third scores on a batter's groundout that turns into an error, the run is unearned and the batter does not receive an RBI. If the runner scores on a sacrifice fly or base hit, the batter gets an RBI.

HISTORICAL CONTEXT
RBI has been an official statistic since 1920, though it was calculated retroactively for many earlier seasons. It quickly became one of the "Triple Crown" statistics alongside batting average and home runs.
Hack Wilson set the single-season RBI record in 1930 with 191 RBI for the Chicago Cubs — a record that has never come close to being broken. Wilson also hit 56 home runs that season in an extraordinary offensive performance.
The career RBI record is held by Hank Aaron with 2,297, followed by Babe Ruth (2,213) and Alex Rodriguez (2,086). These totals reflect not just individual excellence but also longevity and the ability to hit in front of runners consistently.
Modern analytics have somewhat diminished the prestige of RBI as a player evaluation tool because it is heavily context-dependent — a player batting third with three .400 OBP hitters ahead of them will naturally accumulate more RBI opportunities than an equally skilled player batting lower in the lineup.
ERA COMPARISON: HOW THE LEAGUE AVERAGE HAS SHIFTED
Runs scored per team per game is the best proxy for understanding the run-scoring environment that shapes RBI opportunities in any given era.
| Era | Years | Lg Avg R/G (per team) |
|---|---|---|
| Dead Ball Era | 1900–1919 | 4.0 |
| Live Ball Era | 1920–1941 | 4.8 |
| Post-WWII Era | 1942–1960 | 4.4 |
| Year of the Pitcher | 1961–1968 | 4.0 |
| Expansion Era | 1969–1988 | 4.2 |
| Steroid Era | 1989–2005 | 4.7 |
| Post-Steroid Era | 2006–2019 | 4.5 |
| Modern Era | 2020–2024 | 4.5 |
Higher R/G means more RBI opportunities for cleanup hitters. A 100-RBI season was more common in the Steroid Era than the Dead Ball Era. Computed from Lahman historical MLB data.
