wood bats break...when they are younger not as many break due lack of velo and swing speeds. it is pretty simple.
- bad swings and good pitching brake bats
- bad swings vs bad pitching break less but still break
- good swings will get you much more shelf life
- the more aggressive the swing is the more breaks you will get when they make a bad one. it is just a by product of swing speed.
moral...make good swings and have couple spares.
