Much like t2nyval states, if there is possibility that the "questionable fly"
inside the infield could be considered an IF, I call the IFF. That same "questionable fly" when outside the infield will usually not draw my call.
The reason for that is based on the play you cited.
Plays within the infield are too easy to turn a DP with the runners holding whereas it's far less likely on balls outside the infield. The intent of the rule is not to allow a fielder to allow the ball to drop and take an easy double play.
Of course, if I'm
certain that the fly inside or outside the infield cannot be caught with ordinary effort, then there's no call.
Based on factors of fly heighth and ordinary effort,
if in doubt on calling IFF:
- Inside the infield, then make the call
- Outside the infield, then don't make the call
Just my opinion,
