Weighter balls an d curve ball

would this 1: destroy your arm

2: help on training?

( btw last game 11k’s and 1 walk in 5 innings ^^)
we did loose tho:P

i dont think it would help…

if anything it would just flatten out ur curve because throwing a heavier ball can change ur mechanics a slight bit changing the break on the curve

Cuz it Maybe hurts your wrist

but then other way, it makes u develop strength on the pulling down of the arm during the curve, flatenning<-- no way,

if mecha changes with curve it would change with fastballs 2, so i think thats crap^^
