After the hitter has achieved a good base from which to hit,
it is time to execute the swing. The swing is initiated by a sequential
unlocking of body parts. Powerful hitters unwind from the bottom up with a
combination of linear and rotational movement. The back side rotates against a
firm front side. The word firm is important: If the hitter locks the front
side, her weight actually moves back as she executes the swing. This movement
does not allow the hitter to create a positive weight shift that delivers her
energy toward the contact point. When locking occurs, I like to use the term
negative movement (hitters weight is moving away from the contact point).
If we divide the body down the middle from the head through
the belly button, the front side of the body supplies the direction while the
back side provides power. This principle is the same when you are teaching
proper throwing mechanics. Let the back side knock the front side out versus
using the front side to pull the back side through.
A key element of generating the proper leg and hip action is
the position of the back (pivot) foot. By watching the pivot foot on contact,
you can tell what kind of weight shift occurred by the position of the heel of
the pivot foot. Another key is the position of the back leg: L-shape versus
straight leg. We like a hitter to have her heel up at contact. This tells me
that she has achieved a positive weight shift. The closer the heel is to the
ground, the more weight remains on the back side and is not transferred to the
contact point. Some hitters actually finish on the toe of the pivot foot. This
habit is common for hitters who hit off their front footfor example,
Laura Espinoza. Front foot hitters need to be strong in the upper body and
gifted with great hand-eye coordination. Obviously, Laura has both, as she is
the NCAA leader in home runs. As long as the hitter can achieve a positive
movement to the contact point, the pivot foot takes care of itself. I have
found more young hitters who have worked so hard pivoting that they actually
overrotate, forcing their front sides to fly open and create a long swing.
Now that we understand that the legs lead the swing (unwind
from the bottom up), it is time to discuss some key elements of the hand action
to the contact point.
The bottom hand (the pull hand) sets the plane of the swing;
the top hand (the throwing hand) finishes the swing. Both hands work together
and have equal importance. Successful hitters keep their hands relatively close
to their bodies and have a knack for controlling the barrel of the bat.
I use the phrase "Throw your hands inside the
ball". If the hitter is going to deliver the barrel to the ball, her hands
must be inside the ball. Hitters who always try to hit the outside of the ball
often have poor results. The only pitch hit on the back of the ball is the
inside pitch. All other pitches are contacted on the inside half of the ball.
Some common attributes of the upper body in good hitters
are:
Hands are held in a strong position to throw the
bat head (barrel).
Hands are at the top of the strike zone. I like the bottom hand at the top of
the strike zone.
Bat is held at 45-degree angle. Stay away from extremes, like the bat
positioned perpendicular, flat, or wrapped behind the head.
Elbows are down.
Lead arm forms an L.
Both arms form an upside down V.
Front side is soft.
Front shoulder is slightly lower than back shoulder.
Wrists are in an active or cocked position to allow a throwing motion.
