I really can't add much to the conversation, but college coaches are always looking for someone that can pitch well. If you can hit, you will be in the lineup. Do both, the coach basically gets a 2-for-1 guy. However, in college it is hard to pull it off well with double the practice time. Your goal is to get on the field, so many decide to be pitcher only or position only.
(as much as I hate to admit it).... My favorite 2-way guy to watch right now is Adam Haseley at UVA. Played/started every game in CF. Then when they needed him to pitch, he comes trotting in. Led the team in ERA last year, too. Google him. He will be selected early this June.
