What are the specifics of "the infield fly rule"?

Answer 1

With fewer than two outs, and runners on first and second or bases loaded, if the batter hits a fair fly ball (not an attempted bunt or a line drive) that, "with ordinary effort," can be handled by an infielder (including the pitcher and catcher), the batter is declared out and the runners may run or not, as they choose. The ball is still in play.
The purpose of the rule is to protect the offensive team from having a fielder camp under the ball and then decide whether to catch it (if the baserunners attempt to advance) or let it fall (if the runners hold their bases), thereby ensuring a double play through deception.

Answer 2

Less than two outs, and either runners on first and second or bases loaded. Must be a FAIR fly ball which would be a routine catch in the infielder. (A foul pop up is a foul ball, not an infield fly.) That's why, if you hear the umpire make the call, it is "Infield fly, IF FAIR!!!"

It's to protect the baserunners from becoming double play/triple play victims if some crafty infielder camps under the ball then lets it drop.

Answer 3

Less than 2 outs, runners on 1st and 2nd or bases loaded (1st and 3rd does not qualify, as there has to be a force situation at 3rd). Ball hit fair in the infield or could be handled by an infielder, batter is automatically out, runners can advance once ball is caught (must tag up) or hits field (do not have to tag up). No force play exists.

Answer 4

there have to be less than two outs, runners have to be on first and second, first and third, or first, second, and third...it has to be a pop up that stays on the infield in fair territory, which is why the ruling is "infield fly, if fair"

the rule was put into place because smart infielders would often let the ball drop and trap runners into double plays, because the runner on first wouldn't run the play out and when the ball dropped it would be an easy double play

Answer 5

i am sorry that i dont know so well, but ultimately, in order to prevent unfair play, where an infielder would allow the ball to drop and then force a double play, because the runner on first wont run in fear of getting tagged out at first if the ball id caught, the infield fly rule ultiamtely calls trhe ball an automatic out,

Answer 6

The batter is automatic out and the base runners can try to advance to the next base at their own risk.
