Lorenzen makes sense as a reliever due to his late start and inexperience as a pitcher. We're looking at three, four years of development for him as a starter vs. maybe one as a reliever. The problem with developing him as a reliever is if he just turns into a decent middle reliever, which is very possible. He needs to be a late inning reliever for it to pay off.
You generally need three pitches, but you said "But there are some guys who throw high 90's that are so far away from developing secondary pitches", and Lorenzen is already half way there. I just wanted to point out that he does have a good offspeed pitch at this point, since it could have been read that he didn't have anything but a fastball with your quote.
