The Origin Of “Out Of Left Field”

It’s believed that this phrase comes from baseball. However, its exact origin, how it came from baseball, is not clear. Let’s talk about this.

In baseball, there are three outfield positions—the right fielder, the center fielder, and the left fielder. If a ball is hit hard enough, the outfielders will either try to catch it, or they will attempt to retrieve the ball as quickly as possible and throw it back into the infield.

Obviously, the saying ‘out of left field’ is referring to the left side of a baseball field, and the thing coming ‘out’ of it would be a baseball, right? But why specifically the left field, what about the others?
