What is AVG in Baseball?
Batting Average · Batting
Batting Average (AVG) measures how often a batter records a hit per official at-bat. It is the oldest and most widely recognized hitting statistic in baseball. A batting average of .300 has long been considered the benchmark for a quality hitter. Batting average is calculated by dividing the total number of hits by the total number of official at-bats. Walks, hit-by-pitches, sacrifice flies, and sacrifice bunts are not counted as at-bats.
- AVG (Batting Average):
- Hits divided by at bats. .300 is the traditional mark of an excellent hitter.
Data updated
Formula
AVG = Hits ÷ At-Bats
A player with 150 hits in 500 at-bats has a batting average of .300 (150 ÷ 500 = .300). Batting averages are expressed as three-decimal figures.

HISTORICAL CONTEXT
Batting average has been tracked since the earliest days of professional baseball in the 1870s. It was the dominant offensive metric for over a century, and "hitting .300" became shorthand for being an excellent hitter.
Ty Cobb holds the all-time career batting average record at .366, a mark that has stood since 1928. Rogers Hornsby (.358), Jud Wilson (.357), Shoeless Joe Jackson (.356), and Oscar Charleston (.350) are the only other players at .350 or better with sufficient plate appearances.
The "Deadball Era" (1900–1919) featured many high batting averages due to the scarcity of home runs — players prioritized contact and ball placement. The introduction of the lively ball in the 1920s initially raised averages before pitching adapted.
Modern analytics have revealed that batting average undervalues walks and extra-base hits relative to their actual offensive contribution. Metrics like OBP and OPS now receive more emphasis, though batting average remains a fundamental and widely-reported statistic.
ERA COMPARISON: HOW THE LEAGUE AVERAGE HAS SHIFTED
League-average batting average has declined significantly since its peak in the Live Ball Era. Rising strikeout rates have pushed modern averages to historic lows.
| Era | Years | Lg Avg AVG |
|---|---|---|
| Dead Ball Era | 1900–1919 | .254 |
| Live Ball Era | 1920–1941 | .280 |
| Post-WWII Era | 1942–1960 | .259 |
| Year of the Pitcher | 1961–1968 | .248 |
| Expansion Era | 1969–1988 | .257 |
| Steroid Era | 1989–2005 | .264 |
| Post-Steroid Era | 2006–2019 | .257 |
| Modern Era | 2020–2024 | .245 |
