infield fly and an interference

[clev1967]

Interesting in that in reality you are getting two outs on the same act. One out for the pop up the batter hit (IFF) and one for the same pop up that SS is heading for(INT) If indeed SS still had some ground to cover at the time of the INT and INT by rule is a dead ball I am not calling IFF and my defense is that at the time of the INT it could not be judged whether that ball was clearly catchable.
