Was wondering about the rule change that states "smooth cylinder implement from the top of the cap to the top of the knob". Does that mean bats like the Nike models (and others) that have a "break" before reaching the knob will be illegal in 2012? Looking for a definition of smooth clylinder from top of cap to top of knob...... Thanks for any help. BTW I am new to this forum and not interested in reading another link that has anything to do with MLB umps....
