how high does a ball need to be for a infield fly?

[mkolton828]

Situation:

We have runners on first and second with one out. Our batter hits a ball that has little bit of loft on and the 2nd baseman camps under the ball in the infiield grass. Umpire does not call infield fly and 2nd drops ball on purpose and throws to 3rd (force out). third bsaeman throws to seond (force out). End of the inning.

i go to umpire and ask why there was no IFF called. He said that the ball did not high enough to warrant the call. He claims that the ball has to get higher than the backstop fence to call it. I claimed you can call IFF anytime b/c the rule is to protect the runners on base.

Tell mje your opinions, was I wrong or was the umpire wrong.

By the way we lost the game by 1 run.
