i found out that i am double jointed in my right shoulder which happens to be my throwing arm does this give me any advantage against a batter?
Being double jointed isn't really a thing. Joint hyper mobility rather, where you can stretch a joint farther than most people can is possible, but I don't see any distinct advantages to it.
I'm double jointed in both my shoulders i can jump rope with just my hands holding each other
Advantages: further ranges of motion which corelates to more velocityDisadvantages: more susceptible to injury because its loose and not as strong
does it play along with accuracy? or just velocity
Im not sure actually. It may be harder to control the ball because the joint is so loose but thats just a theory.
it allows me to pitch often
