In baseball, a hitting streak is the number of consecutive official games in which a player appears and gets at least one base hit. According to the Official Baseball Rules, such a streak is not necessarily ended when a player has at least 1 plate appearance and no hits. A streak shall not be terminated if all official plate appearances result in a base on balls, hit by pitch, defensive interference or a sacrifice bunt. The streak shall terminate if the player has a sacrifice fly and no hit.
