Base on balls

In baseball statistics, a base on balls (BB), also called a walk, is used in baseball to track the performance of pitchers and batters. If a batter receives four pitches which the umpire calls balls, he is entitled to "walk" to first base. Receiving a base on balls does not count as an official at bat for a batter but does count as a plate appearance.

A pitcher can also choose to intentionally walk a batter. This is usually done for the purpose of facing a different batter that the team feels they have a better chance of getting out.
