Getting back in to baseball at 14

Okay, I had played baseball up until I was twelve years old, but family issues and the like got in the way.

I come back now, and I have a fairly weak arm, I can probably get it in there at like 40-50 MPH. I’m a natural sidearm thrower, as well as a lefty.

If I were to get back in to baseball, should I attempt to work out and pitch, or would I be better off playing a position?
