Infield Fly?

[scyguy]

The Infield Fly rule does not mean an outfielder cannot catch the ball as well. No rule that I am aware of that makes it against the rules for an outfielder to catch a ball you declare an infield fly. At least not with the FED Rule. But I would not be surprised if somewhere there is a difference

Partner and I were discussing this in pre-game last night. We wondered about the outfielder making a catch and it still be considered an infield fly. Makes sense if it is ordinary effort and within the general area of an infield fly. Someone know if this is legal under FED??
