The first thing I see is that your plant-foot is consistently pointing towards 1b which will not only make you lose some velocity but also effect your control.
Although its not a big change in your mechanics, you should see a difference in your control and velocity.
Overall, it looks very good. Keep up the hard work.
Thank you, I have never really thought about that, I will be sure to work on it!
What lefty said.
The foot plant is huge! I couldn’t hit the broad side of a barn before I started planting my foot towards home plate consistently.
