I'm sure this has been brought up before but I thought I would bring it up for shits and giggles....
So is there a difference?? Here is my take on this one...YES there is, I'm no hitting instructor or expert but I played baseball before I transitioned to mens fastpitch. Granted it was mens league and the pitching was decent to good at times however, I was able to hit pretty well in baseball.
Transitioned to mens fastpitch struck out approximately 30 times once even letting go of my bat (embarrassing story) before I finally got a hit. It took me a loooong time before I became a decent hitter in fastpitch. To be honest the only thing that stayed the same about my swing was my load and separation my swing plane and approach completely changed . My baseball swing was not very effective against fastpitch shooters at all!! Like I said I'm no hitting guru this is just my experience but I have seen some college hitters look very similar to baseball hitters.......
