Strat-O-Matic Baseball 365

I see this in the play by play.
PassRecvp
What does it mean?
Under what circumstances does it occur?

Copy and paste the whole play result

I have a couple results with some wording I do not understand, either. Is there a list on the website that explains the play results?

We need 5 in All Time Football...first come/first serve!
