When something comes out of left field that means it was surprising or unexpected.
The Origin Of “Out Of Left Field”
The phrase out of left field might originate from baseball. How so? Let us see why:
In baseball, there are three outfield positions—the right fielder, the center fielder, and the left fielder. When a ball is hit hard enough, the outfielders job is to catch it, or if the ball touches the ground, they retrieve the ball and throw it back to the infield.
The saying out of left field must obviously be referring to the left side of a baseball field, and the thing coming “out” of it would be the baseball. But why is this phrase specifically about the left field, why not the others? Well, concerning that, there’s one explanation that suggests the following:
Imagine this scenario—A batter hits the ball and there is a base runner sprinting towards home plate. In this situation, the base runner is facing away from the left field. So if the left fielder scoops up the ball and throws it to the baseman on home plate, the runner would be unable to see it coming, thus it would catch him by surprise.
