Before you focus on how you can improve, it's important to understand what you do well. Most people will tell you that it's important to improve upon your weaknesses, but I'm telling you to recognize your strengths and continue to make them stronger. For example, how many pitchers are known for having a great curveball, a knee-buckling change-up, a riseball that makes every batter chase, and a drop ball that falls off the table? I'll be honest with you, I have played with and against a lot of great pitchers, and most of them have two or three pitches that define them. Recognize your strengths, continue to train them, and be the best version of you.
So, what defines you? What are your best two or three pitches? How do you get batters out? Take a minute to identify if you're a pitcher that produces weak ground balls or pop-ups. Think about how often you generate swings and misses.
Now that you've identified what you do well in games, start to ask yourself how you do it. If you get a lot of groundballs, you probably throw an exceptional drop ball or a fastball with great topspin. If you typically generate pop-ups and swings and misses, maybe you have a great riseball. Whatever it is that you do well, keep that in mind as you read through the rest of this article.
