In baseball, an intentional base on balls, usually referred to as an intentional walk and denoted in baseball scorekeeping by IBB, is a walk issued to a batter by a pitcher with the intent of removing the batter's opportunity to swing at the pitched ball. A pitch that is intentionally thrown far outside the strike zone for this purpose is referred to as an intentional ball.
