MLB play - could it be different in softball?

I had a different situation with similar results a few years ago in a Varsity game. I was BU. 2 outs, no runners. Line drive hit to F3 who caught it on one hop. PU immediately called it a catch for 3rd out. BR stopped running, F3 just started to run off the field without touching 1B. OC asked PU to get help. He came to me and asked if I had a catch. I told him the ball had been clearly caught on a hop. PU asked what should we do? We decided to stick with the original call and call it a catch and 3rd out. I don't know if that was correct or not but didn't know how to fix it.
