The MLB batting title is based on plate appearances, not just at-bats. For a 162-game season, a player needs 502 plate appearances to qualify, which is 3.1 per team game.

Quick Scoop

  • Not a fixed at-bat number. Walks, hit-by-pitch, sacrifice flies, and similar events count toward plate appearances, even when they are not official at-bats.
  • Standard threshold: 502 plate appearances in a full 162-game MLB season.
  • Exception rule: A player with fewer than 502 plate appearances can still win the batting title if adding enough hitless plate appearances would still leave him with the best average.

So the simple answer is: you do not qualify by a certain number of at-bats; you qualify by plate appearances, and the usual MLB cutoff is 502.
