Your line up card

[SWFLguy]

^^^^^^

Agree--- we had a presentation at an early meeting and I was lost/bored after a half a minute of it. I simply write a sub's number where she enters the batting order and strike a line through her name on the sub list. If she leaves the game I put a line through her number in the batting order. If her number shows up again (re-enters)it is not rocket science to know she can't do it again.
99.9999% of the time there are no problems--even with the Flex/DP. If I ever have a VERY rare time that there is a problem, I'll simply stop play-get both books together and hash it out. It is rare as most high school teams here have so few players that substitutions are not a problem.
Oh--my Honig's "Trip Card" has a place for Courtesy Runners on the back and I use that. There are a few teams that use courtesy runners and I usually thank coaches who do especially for the catcher as it speeds up the games a bit. I wish we would just go to a "speed up rule" like was used when I did college/JUCO ball in CNY.
