Pre-game meeting with partner -- looking for sources

[NCASAUmp]

I usually just cover the basics:

1 - Ask them if they ever go out on a fly ball, and if so, what do they yell?
2 - Go over tag-up coverage
3 - Go over who has which bases, and when (trailing runner, etc).
4 - Ask them how they want to handle swipe tags or tags to the body on the BR (front vs. back).
5 - Remind your partner that you'll do your best to help them if they're in trouble.

No two pre-games are ever going to be the same. Some umps NEVER go out in a 2-ump system, and some do. Some umps don't move very well to take the trailing runner into 3B on a triple with no runners on base. You just need to find out what to expect from your partner during the course of a game, what kind of style they have, and that's what the pre-game is meant to do.
