I'd like to thank those of you who took the time to reply to my question. The term "ugly" in this case was not used to describe a play, a swing or anything other than the players physical appearance. It wasn't used in a humorous way, here are a couple of examples: "Ugly, get a glove & warm up right." or "Ugly, grab a helmet, you're on deck." Whether or not he is (ugly) would'nt be for me to say, and certainly not in a forum as this. This is now the kids nickname, the kid didn't want it, and his father sure doesn't like it. Gee, thanks coach.
As far as me being too sensitive or politically correct. The kid is not my son, if it were the coach wouldn't ever call him that again. I think that a man calling a boy by a derisive term just to mock him shouldn't be tolerated. We're talking about a 15 or 16 year old kid. Aren't they screwed up enough without someone they are supposed to admire running them down? I played ball, and NEVER heard anything as this. Sure we had nicknames, usually just shortened versions of our names, and no, this boys last name isn't Uglyinsky. I had one coach who apologized for getting mad and saying GD. This was the coach who we went 25 - 0 for. You don't have to be a jerk to win games.
I'd also like to say that I posted in 3 forums, not 4 or 5, so that I could glean a response from my area (California), the general items area, and the coaches area. I doubt we all read every post in every area, and apologize if I used up too much bandwidth.
My next question will be about pitchers, I'll start a new thread.
