A couple of rules from the ISF rule book:
When it seems apparent that a batted ball will be an infield fly, the umpire shall immediately declare, "INFIELD FLY, IF FAIR-THE BATTER IS OUT," for the benefit of the runners.
This emphasizes that the verbal call of "Infield Fly" is solely for the benefit of the runners, not a final, unchangable declaration of whether the batter is out or not.
The umpires, in consultation, may rectify any situation in which the reversal of an umpire's decision, or a delayed call by an umpire, places a batter-runner or runner in jeopardy, or places the defensive team at a disadvantage.
"Any" means, well...ANY. The Infield Fly falls under that jurisdiction.
