Yup, I'm used to same terminology as Standball but just semantics.
Dadcoach, everyone from at least HS JV up (if not younger) teaches and encourages players NOT to avoid HBP (unless at the head) but instead, how to get hit properly. Sorry, good hitters do not avoid HBP. OP is a teen and struggling with fear of HBP. The last thing he wants to be thinking about is to move to avoid being hit. You must be dad of a pitcher 
Dadcoach,
Congrats on son's good start!
Sorry, the "you must be dad of a pitcher" was somewhat tongue-in-cheek... and based on the fact that your bio says you are a "dad of a pitcher"
.
I will admit this is a tricky situation with a player who has fear of getting hit at this stage of the game (assuming I am doing the age math correctly? - see my initial post). And I don't claim to know, definitively, the best answer to his problem. But I do know that the large majority of HS and college coaches will require a player to wear a pitch as opposed to "practice getting out of the way of the ball" and this is not limited to weaker hitters.
I have coached HS V (still do) and travel ball, study my craft and network with coaches at all levels. We currently have six kids from our HS program playing college ball and I follow them and their games closely as well. I've been in organized baseball for well over 40 years (ouch, I'm old). I have never seen or heard of a HS or college coach teaching a player to get out of the way of a ball or avoid getting hit by it, as you state. The standard is to teach how to wear it properly and take the base they are giving you. I don't see how Ryymann can benefit from working on "getting out of the way" as his solution and still expect to become a successful hitter. I'm always open to learning new thoughts, though, so please expand.
Ryymann, please tell us your age and current playing level so we can fine-tune our advice.
PS - Sorry, I hate the fact that I just stated credentials. Just trying to give some point-of-reference background to keep the discussion progressing so that the OP may benefit.
