What is the origin of the term hot corner in baseball?
The "hot corner" in Baseball refers to the third base position. Since most batters are right handed, when they pull the ball down the third base line, they are hitting it in their power zone. Since the base is 90 feet away, the third baseman is required to have the best reflexes. So if you are playing the "hot corner" the ball blazes by you at a high speed and you must be able to react quickly to make the play.
