Re: linear vs rotational controversy

But, keep in mind, that the basis for definitions of swing mechanics at Batspeed.com is derived from the forces a batters transfer mechanics applies to the bat (CHP, THT and BHT).

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.

Since I had never heard the term "linear swing" until I found this board, I would have to say that the teaching of the downswing would be what I feel is a linear swing. The Lau Sr. Hriniak method of hitting. It really won't allow your elbow to get into the slot and is more of an arm swing down to the ball approach. If we are just going to define "linear" then we could check out the word in the dictionary, but for me it is the Hriniak approach to hitting that I would call linear if someone asked.
