Fed vs. OBR

[Lapopez]

I am pretty well versed in OBR and just OK in FED. The game I was doing tonight was considered PONY and I don't even know if they have their own rules but when in doubt I usually quote OBR and I am usually able to sell it, as I did tonight, to the usually ignorant coaches. There was a pop foul that was caught by F3 clearly in the dugout area, as was defined before the game. I called the batter out. I got some argument but I sold it. I'm pretty sure this is a legal out in OBR but is it in FED? Can someone give me the appropriate citation as well? Thanks.
