From BR Bullpen

A walk or base on balls, abbreviated BB, occurs when a player gets on base by drawing four balls from the pitcher. A walk might be intentional.

For batters, it counts as a plate appearance, but not as an at-bat; a high number of walks drawn is a sign of a good batting eye, or of a very dangerous hitter that pitchers are trying to pitch around.

A walk is also a statistic for pitchers, where a high number of walks allowed indicates a lack of control.

The ball is live during a base on balls, and therefore, baserunners as well as the batter-runner are allowed to advance additional bases at their own risk.
