First, I have had a few inaccurate line-up cards over the years, the most recent was yesterday. Typically a wrong number, sometimes wrong positions. I dont' think it is that uncommon (these are coaches we're talking about
)
Second, when the nickname was used in the batting order, was it a pre-printed card with full names at the bottom? If so, I have no violation. I have the proper last name and number in the BO so I don't need anything else; it is superfluous and can be ignored. If not, then I don't know who she is so if the nickname isn't another form of her name then it's inaccurate.
