IBB = Intentional Bases on Balls which is also known as an intentional walk

BB stands for "Base on Balls". It refers to when a batter receives four pitches determined by the umpire as balls before the Baseball is either put into play or receives three strikes. In such a case the batter earns a free base and can walk to first base. The batter has received a base on balls.

A base-on-balls is an instance in Baseball where the batter is allowed to go directly to first base, due to the opposing pitcher delivering four balls.
