This one takes the cake. Batspeed.com offers invaluable information about the rotational swing, as do one or two others. Except here we have posters that question the moderator about every minute detail in the rotational movement. At the moment anything linear is seen, or claimed to be seen, they scream that the rotational swing is flawed or that it proves there is a linear/rotational combination. Now these same individuals are eulogizing MLB players and giving their opinion making it look factual. Now they are EXPERTS in every aspect of baseball, right down to the personal struggles some MLB'rs might have to get an 'unregulated' edge on their game.

Oh Guru-JIMA- and others. As an Engineer with his Masters Degree in Elec./Mech. field, Physics is a core science to be able to function in thses areas. I can guarantee you all that by nature (physics), angular displacement (rotation) is far more efficient to generate kinetic energy than linearly. Mass about an axis maintains itself longer because of the centrifugal dynamic that occurs. Since it relies on the bigger and heavier muscles to generate this energy, the arms and hands are free to act as mere linkage and guiderail. Doing so, it allows the batter to make adjustments 'on the fly'. This is possible because the arms and hands are not stressed to generate the energy. The key here is adjustment....when a batter in the MLB utilizes an inside-out swing, it looks linear, but what it infact is is an adjustment to his swing on the fly. Since the shoulders are rotating in an upward motion, it really isn't a linear motion, but rather- casting out. Ok energy is lost, but the goal with inside-out hitting is contact.....

Jack, I wish you luck. I believe in your standpoint. Either rotionally or linearly...NOT BOTH!!! And I choose rotation, not because you say so, but because I am a thinking individual, AND I witness ALL great MLB players (ok 95%) use this same technique.

The Hitman!
