umpire's lineup card

[newkidonthenet]

I'm new! Because of overlapping for switches, I'm having a lot of trouble keeping track of the lineup after rotations. I wonder if other umpires are having this trouble, or if they ignore it because of more "important" considerations, or if it's really an experience thing that will come EVENTUALLY, or if there's a lineup card system that can really clarify this for me. Thanks for input!
