H/E
Hey Shelby,
I wasn’t sure the best way to answer your question (Should I email you or write an answer through my blog?). I went with this so that anyone else wondering the answer would be able to see it. The H/E is Hit/Error. After each ball in which the batter reaches base safely, the score keeper will flash up an H or an E to let everyone know how the play was ruled. Often times when you see a position player bobble a ball or not make a play for whatever reason, you will find both he and the hitter (now baserunner) looking at the score board. This is why they do that. I hope that answers your question.
If you or anyone else has questions, feel free to ask. I will do my very best to answer them to the best of my knowledge and as quickly as possible.
God Bless

Hey Barret! Thanks for the answer – that’s what I thought, but never noticed it when there was a base hit or *cough* Frannie’s error *cough*. It must be a quick flash then, that doesn’t stay on the board for the entire half inning . . . makes sense!Maybe next time you should email me instead – I feel dumb! C’mon now, I’ve got an internet reputation to maintain! Just kidding, of course. But hey, I’m here for encouragement, so if you’re in need, let me know!Thanks again,Shelby
