Do you like pitching? If so, then why not develop the skill?
At 15, it seems to me anyway you can get yourself on the field is a good thing. As stated above, you need to be mindful of overuse.
My son didn’t pitch in HS until his senior year (he was a corner infielder), and then only as a closer or stopper. He was drafted as pitcher, so you never know where expanding your abilities can take you (true for all aspects of life).
