My boy was a RHP/C right up until high school when his travel coach (a well accomplished RHP) told him he needed to choose. His biggest issue was, not only the different mechanics, but the wear on the arm. No position on the field throws the ball more than the pitcher and catcher by far. That repetition is a recipie for overuse and injury. Since entering HS (he's a 2018), he has been a RHP/OF and that's done quite well for him.
