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.

Get the Infield Fly Rule mug.
Baseball sexual metaphor for when there's an unequal ratio of males and females at a party and one member of the dominant group leaves to create an equal ratio.
John called the infield fly rule at the party and left so it didn't turn into a sausage fest.
