Besides, I'm pretty sure that any reference to "swing" when referring to baseball intrinsically includes all stages or phases. Same thing goes with golf. When you talk about a golf swing, you're not just talking about the down swing.
On this note, I actually define the swing (as do most biomechanics studies) as the rotational acceleration of the bat from the set position up until contact with the ball. Prior to that is what they call the "loading phase", and immediately after contact is the "follow through phase".
In any case jose, I think we both agree on the same point, just have different definitions of the word "swing". If mak1277 meant swing as you define it, then he is correct.
