• He receives a base on balls (BB).
• He is hit by a pitch (HBP).
• He hits a sacrifice fly or a sacrifice hit (also known as sacrifice bunt).
• He is awarded first base due to interference or obstruction, usually by the catcher.
• The inning ends while he is still at bat (due to the third out being made by a runner caught stealing, for example). In this case, the batter will come to bat again in the next inning, though he now has no balls or strikes on him.
• He is replaced by another hitter before his at bat is completed (unless he is replaced with two strikes and his replacement strikes out).

打数（だすう、英語では "at-bat" ）は、打席数から四球、死球、犠打、犠飛、打撃妨害、走塁妨害の数を除いたものである。

打率、長打率、本塁打率等は、打数を分母または分子としており、打撃成績を述べる上で常に言及される為に注目度の高い記録であるが、近年野球への統計学の応用が進んだ中で、攻撃における四球の重要性が明らかとなり、四球を排除している打数の重要性は下がりつつある。
