Top Hand is the Speed Hand, and the Front Side is Soft
Amazing how many guys that play this game at the high levels and have been successful hitters have absolutely no clue how they do it.
The hands and arms don't provide any power at all, they simply transmit the power generated by the torso and body weight and guide the barrel to the ball.
The top hand is the speed hand if that is what they are talking about and all great hitters have a soft front side. I would also bet that Tony LaRussa doesn't know squat about breaking down hitting!
Swing Smarter Response:
You are right on Mike! As Jim Lefebvre puts it, Centrifugal Force, like twirling a rock on a string and letting it go in a certain direction (hand holding the string being the legs and hips; string being your arms & hands; and the rock is the baseball).
Also, as Jaime Cevallos puts it in his Positional Hitting philosophy, the arms and hands provide the "whip" from power generated in the legs and hips.
Most definitely God gifted Big Leaguers with the skill to play the game beautifully, but I call it "Ignorance on Fire."
My older cousin, who runs his own successful Dental practice, also put it plainly to me over a decade ago, "Your teachers are the ones who've failed." Looking back on that statement, even though at the time I thought it was sort of pompous, there's more to it...you learn more failing big once than in 100 wins.
I would rather learn from someone who's struggled and had to self-instruct, than someone who's drifted through the system unblemished.
I would love to hear from the Swing Smarter community on this... :)
