 Yeah, I think usage is a big one. I think being able to use the slider more to righties is going to open up the changeup, being able to never stop pitching off my fastball and stuff like that. But when it comes to analytics, I think that I have a really good understanding of what my stuff's going to do, and I feel good with it right now, and I can compete at this level for sure with what I have. Do you ever feel like you want to unveil the lefty on lefty changeup?
