A quick reminder — we have been having some issues with pregame communication among officials. 
If you are assigned as the Umpire or Field Judge, it is your responsibility to contact the Referee 3 or 4 days before the game to confirm the assignment and all pregame arrangements (e.g. meeting time and place, what uniform to wear, and any special instructions).
Pregame communication is an essential part of being a successful crew!
If you are the Referee and you have not heard from your crew within 48 hours of the assignment, please reach out to them.
if the Referee has not had any communication with any member of the crew 24 hours before the game, contact the assignors at [email protected].
