What is Infield Fly Rule?
1.
If there are runners on first and second(Or the bases are loaded) and less then two outs when the batter hits a pop-up to the infield, he is automatically ruled out to prevent fielders from dropping the ball on purpose to try to turn a double play.
Since the bases were loaded with no one out, that easy pop-up became an infield fly, so the third baseman doesn't need to catch it.
2.
Somebody explain this
