Need Control Help

I’m about to be a junior in high school and I don’t have great velocity so I’m thinking I should really work on control. What can I do to help with my control. I know it comes with practice but is there like anything like drills or specific mechanical things to work on?

Do you have access to a video camera and a catcher?

If you can post a video of your mechanics we can really help you because control problems are usually mechanic related.

Here’s the only video I have of me pitching right now.
