I have no idea what you are working with in terms of repitiore and you're overall pitching abilities, but you can still succeed as a pitcher with a bad defense behind you. I don't know what you are working with in terms of a defense either, but some of their failure could be due to the speed at which balls are being hit at them (once more, no idea about you scenario, simply guessing). Whatever route you are taking to get outs right now -- be it via the groundball, the flyball, the strikeout, or any from of contact -- orient it more toward the strikeout and WEAK contact. Until my final year of high school, I pitched to get any kind of out I didn't care how I got it I just tried to get it. I changed that my senior year. My new approach was more contact oriented than yours probably should be (I had a very good high school defense in every position) but it was focused on WEAK contact. Any way you can set up a batter to make weak or bad contact you need to do so. The main thing here is MISS BARRELS. The farther away from the barrel the ball makes contact, the weaker the contact. This should help reduce hot shots, ridiculous hops, or other things that happen with hard contact. The biggest precaution to this is that you will field your own position more than you ever have before.
I hope this helps, good luck!
