Baseball questions and advice?

Alright well for the hitting thing, that's just baseball happens to everyone. You'll get those little dinkers that fall in for hits and also those will eventually start falling in also. For the fielding just repetition repetition repetition will be the only thing. The more that you continue on working at that part of your game the more confidence you get and the better you are. While pitching wear a jacket and put it on your arm, so that it stays warm, if that doesn't work get a band and do exercises between half innings to keep it loose. Your arm is always gonna be a little sore after you pitch, it's just called having a tired and used arm. Ice it that's all you can do. For stamina you run long distances but also short sprints in quantity since you're also a shortstop.
