Base on balls
A base on balls (BB) is given to a batter and against a pitcher in baseball statistics when a batter receives four pitches that the umpire calls balls. It is also known as a walk.
Intentional base on balls
Another version of base on balls is called intentional base on balls (IBB) or intentional walk. This is when the pitcher deliberately pitches the ball away from the batter in order to issue a base on balls. As with any other walk, an intentional walk entitles the batter to first base without being able to be put out, and entitles any runners to advance if forced. Intentional walks are a strategic defensive maneuver, usually done to bypass one hitter for one the defensive team believes is less likely to initiate a run-scoring play (e.g., a home run, sacrifice fly, or RBI base hit), or to set up a double play or force out situation for the next batter. They do carry an inherent risk, however, as they give the offensive team another runner on base, without any effort on their part, who could potentially score a run.

A depiction of the strike zone. A base on balls occurs as a result of a plate appearance during which four pitches are thrown out of the strike zone that the batter does not swing at.
Mark Hendrickson of the Florida Marlins intentionally walking the Atlanta Braves' Yunel Escobar in 2008. Note the Florida catcher, Mike Rabelo, in a standing position behind the opposite batter's box to receive the pitch. This method of issuing an intentional walk is no longer used in Major League Baseball.
