Bat Speed -- Baseball Hitting Forum

Posted by: Mac () on Fri Jan 10 22:47:36 2003

The debate on rotational mechanics and linear weight transfer mechanics is as old as baseball itself. I'm not convinced it will ever be agreed upon, mainly because neither term really applies to my way of thinking.
> Unfortunately the body is not constructed with a single pole in which to rotate upon, in fact, our legs, are like that of a tripod. They help keep us grounded and if one leg is straigter than the other we have hip or spine tilt. This straightning of the front leg is what generally turns a level cut into a slight upswing, or in some cases an extreme uppercut. The hip joints themselves do not turn, it is the torso, constructed from the base of the spine that creates the torque. However in an effort to add upper body torque, many hitters feel the strong need contribute excessive leg action (ie..hip thrust) to get the torso to turn. Normally it is young hitters that create this excessive leg action that never really feel the torso power. In other words they combine the torso turn with the leg thrust. This excessive leg action is what most hitting instructors have the hardest time seeing and teaching.
> I have a real concern with anyone that preaches straight legs in the baseball swing, mainly because straight legs create angles and also lock hips, which contribute to bad balance. In any sport that I lock my legs I get beat. Lock the front leg early in a baseball swing..... and I'll get beat. Now I must say, great hitters do lock there front leg normally (not always), however, it comes with a price even for them, but the real issue is how they go about locking the front leg. Getting into that all too familiar "sit to hit position" is the art of a great athlete and generally a great hitter. In viewing Jacks video I see the kids just straightening the front leg, with never the notion of sitting to hit. But then I see the hitting instructor, getting a nice front knee bend, thereby, positioning the legs for all of this upper body torque. In golf they call it the "magic move." This magic move is a slight lateral slide while the upper body begins it unwinding (rotation). This to me is why the debate is never ending. Great atheletes/hitters can do both at the same time, but when either becomes excessive , then you have a issues in my opinion. This is why everyone looks different when they swing in my opinion.

If I can get a kid to keep this leg in contact with the ground at the initiation of the swing, but with good flexion and stability and I give this kid the best opportunity to be succesful. If I see kids locking legs than he or she will have problems, until they understand how the front leg is supposed to lock, by rotating laterally with athletic legs.

>>>>Coach C, actually, the debate on rotational mechanics and linear weight transfer is not that old. Charlie Lau Sr. started teaching linear technique about 25 years ago and after he passed away, Walt Hriniak went on with it during the mid 80's through the early 90's before he was let go. Prior to Lau, everything that was taught was rotational. Good rotational mechanics were taught at that time to help the player not hook and top balls that were pulled. Before the metal bat, all the good young hitters pulled the ball and after they signed they were helped to hit the ball the other way.
There have been three culprits that have held back young players from developing into good hitters 1. Linear mechanics 2. the metal bat.3. Guys trying to reinvent the wheel. If you teach a player to start with his arms, he will cast the bat and with wood, he will break enough to cost you to have a second job. I see over 200 games every year, and the thing I don't see very often is the young player who can pull a ball hard, in the air and not hook it. The reason is twofold; coaches who only want the players to use the off field to hit in and linear swings. I play a lot of golf too, after spending 37 years in pro ball. Mac>>>>
