My main objective is to learn to take velocity off of my curveball. For background, I throw a low to mid 80s Fastball, A hard slider (76-79), a split change (75-77) and I currently throw a traditional curveball (74-76). I obviously need to learn how to change speeds better. I am okay with my slider and split being similar speeds due to the difference in movement of the pitches; however, My curveball is my weakest pitch (Still a pretty good one). My curveball has similar action to my slider as well. I am interested in hearing how i could slow this pitch down preferably to the low 70s and get more of a 12-6 action. I would be willing to work with new grips if necessary or just listening to any advice you may have to improve the same I’m already throwing. I look forward to your responses.
