For it to be an infield fly the ball has to be catchable by an infielder with "normal effort". Unless the infielder was literally standing in the outfield on a ball hit into no mans land those balls could not be caught with normal effort.
Unfortunately, this is the reason/excuse I've most commonly heard when the umpire obviously brain-farted and didn't call IFR. To be able to "fix" the problem, it requires that the umpire(s) first acknowledge they made a mistake. I have a lot of respect for those that do admit when they screwed up (i.e., yeah, that should've been called a ball instead of a strike, but don't expect a make up!), not so much for those that don't.
