My DD's 12U town travel team is about to start playing games. I am an AC and DD is a pitcher. She throws a fastball and change-up. As far as pitch location goes, she has two: strike and non-strike. What is the best way to call the change-up? Should I give signal to catcher, who then flashes sign to DD? If so, what is the best way to do this, without allowing opposing coaches to steal sign and start calling out pitches? Should I leave it up to our relatively inexperienced catcher? During a few rec games this year I sat on a bucket and signaled the catcher, while 3-4 opposing coaches lined up at the fence trying to figure out what I was calling. Thoughts?
