What constitutes an infield fly rule in baseball?

Answer 1

The infield fly rule in Baseball is a rule that is called by the umpire to protect the offensive team. It is called when there are runners on first and second base (or bases loaded) with less than two outs, and a fair fly ball is hit that can be caught by an infielder with ordinary effort. When the umpire calls the infield fly rule, the batter is automatically out, regardless of whether the ball is caught or dropped. This prevents the defensive team from intentionally dropping the ball to try to get a double play.
