Pure linear mechanics would generate a straight (A to B) hand-path and the force from each hand would be inline driving the bat linearly knob first at the ball. – I might add, that prior to this site coming online with findings from my study, those linear principles, "hands extending A to B" and "knob to ball" were taught by the vast majority of coaches.

Rotational mechanics supply these forces by generating the optimum angular displacement in the hand-path while the hands apply force to the bat from opposing directions (torque). Therefore, I think you can see the problem I would have with a post that refers to Arod as having linear mechanics. But the poster may be right with his definition of linear mechanics.

Obviously I forgot to include rotation around a stationery axis for lower half mechanics in my suggested definition of linear.

Anti-Spambot Question:

This song is traditionally sung during the 7th inning stretch?
   All My Roudy Friends
   Take Me Out to the Ballgame
   I Wish I was in Dixie
   Hail to the Chief
