I started umpiring when my son went to college and I no longer had an excuse to hang around baseball fields. After working 13U/14U youth games with free defensive substitutions, generous courtesy runner allowances, and everyone batting, I'm now working JV games and need to get a better handle on tracking substitutions, lineups, conferences and such matters.
Last night I worked a game in which the visiting coach handed me a line-up card that had 13 potential substitutes written in microscopic letters. As his team built a larger and larger lead, he worked nearly every one of those substitutes into the game. My notes were an illegible mess and would not have been any use at all if I had needed them to resolve a controversy.
So I'm looking for advice on quickly jotting down the right information and having it available if I need to sort something out. What information really needs to get written down? Is there a system or format that serves you well?
