In baseball, an at bat (AB) or time at bat is a batter's turn batting against a pitcher. An at bat is different from a plate appearance. A batter is credited with a plate appearance no matter what happens during his turn at bat. A batter is not credited with an at bat if he:
- Receives a base on balls (BB).[a]
- Is hit by a pitch (HBP).
- Hits a sacrifice fly or a sacrifice bunt (also known as sacrifice hit).
- Is awarded first base due to interference or obstruction, usually by the catcher.
- Is replaced by another hitter before his at bat is completed, in which case the plate appearance and any related statistics go to the pinch hitter (unless he is replaced with two strikes and his replacement completes a strikeout, in which case the at bat and strikeout are still charged to the first batter).
At bats are used to calculate certain statistics, including batting average, on-base percentage, and slugging percentage. A player can only qualify for the season-ending rankings in these categories if he accumulates 502 plate appearances during the season.[1]
Pete Rose[2][3] is the all-time leader in at bats with 14,053, and the only player in MLB history with more than 13,000 at bats. Only 30 MLB players have reached 10,000 career at bats. As of September 22, 2024, no active players are in the top 100 of career at-bats. The active leader is Andrew McCutchen in 169th with 7,862.

Notes
- ^ In 1887, Major League Baseball counted bases on balls as hits. The result was high batting averages, including some near .500, and the experiment was abandoned the following season.
- ^ A player is considered inactive if he has announced his retirement or not played for a full season.
