Before the 1920 season, the catcher was allowed to set up anywhere within a roughly 14 by 20 feet right triangle behind home plate, the back line being 10 feet behind the plate. The catcher could stand at a corner of this triangle to receive the four wide pitches, too far away for the batter to have any chance at hitting the ball. As the intentional walk became more frequent following the end of the dead ball era, batters such as Babe Ruth complained about the unfairness of it.
