In baseball, an intentional base on balls, usually referred to as an intentional walk and denoted in baseball scorekeeping by IBB, is a base on balls (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. Since the 2017 season, intentional bases on balls are issued to the hitter at the discretion of a manager.
Barry Bonds[1][2] is the all-time leader in intentional bases on balls with 688 career intentional walks. Bonds is the only player to be intentionally walked more than 400 times. Miguel Cabrera is ninth all-time and the active leader with 238 career intentional bases on balls.
