do you have your stats from last year?
where are you from
what is the name of your team and level of competition.
how many innings
% of strikes and balls
major tournaments you’ve pitched in.
majors level teams you’ve faced and how did you do.
what is the velocity of your pitches (i know you’ve posted your fastball, but there’s more to it than that)
it’s the time of year to evaluate where you are, what you need to work on (which is what you’re doing and that’s good) and how to get better.
you may not need another pitch, may need to refine and develop what you have. if you have a major mechanical flaw you may break no matter what you do. (as you throw harder you may break also (at least 1/2 of all major league pitchers do at some point throwing at 85+ velocity and something to think about)
won’t know until you look at the stats and post a video clip at least from the side and ideally from the side, back. behind the mound and the plate.
then you can get some very good advice (that you may or may not want to use) to build your personal program.
this is how serious, elite level players develop what they do, then the difference between the elite levels and the wanna-be’s are the elite level guys do it. lots of people have a plan, few put in the effort that most other people will not do. people who get it done are called ballplayers and champions .
i’ll help you if you’ll do these things.
