Well, I am 14 and haven’t played baseball for a while, but have worked on arm strength. In PE we are starting a baseball/softball unit and I’m trying to throw. I grip the ball (we use softballs so that might be the problem) like a normal 4SFB but when i throw the ball it manages to break away from left handed hitters almost like a slider I believe. Then later i threw the same way but it sank alot more like i was trying to throw a sinker which i wasn’t. I don’t really have a conventional motion i throw kind of sidearm but not entirely. I can’t really explain how i throw the ball but i want to know why it breaks so much.
Also, for future referance, I’d like it if someone told me how to throw an eephus without requiring a PhD in baseball…
