Swing Finish
It
is very difficult to analyze a batter's swing without somehow slowing
the action down, or even stopping a swing in progress. One image
that is easier to analyze is the last image seen - the swing's finish.
A lot can be seen from the finish. Obviously, if the batter's front
foot is almost out of the batter's box, the batter has "stepped
in the bucket" and overextended. Here are some things to look
for in the swing finish that can be seen in the photograph at left.
Back Side Commitment
This is often called "squishing the bug", but the term
implies that you must keep some weight on the ball of your back
foot. This violates the tenants of hitting coaches who teach that
you should hit with your weight on the front foot. Regardless of
the batter's front/back foot weight distribution at contact, the
point is that prior to the swing the rear foot should point toward
the plate, and through the course of the swing twist and finish
pointing toward the pitcher.
The knee should also be bent to near 90 degrees. This twisting
action gets the hips into the swing. The hips are key to increasing
bat speed and generating power from the legs. Unfortunately, a player
with good reflexes, quick hands and good hand/eye coordination can
survive through AAA without good back side commitment. However,
the increase in pitching velocity at the majors level makes it difficult
to catch up to the pitch without "squishing the bug."
Front Side Closure
While the back side is twisting, the front side should not. It should
stay near the "closed" position. Closed means that the
front foot is pointed more toward the plate, than to left field.
Once the front foot opens, hips and shoulders tend to follow. It's
great if the hitter wants to pull every pitch, but as the player
progresses up the ladder of competition, the pitchers will catch
on and pitch to the hitter's weakness, the outside pitch.
Head on the Ball
I think we can still call this "Mike to Ike" without offending
any hitting gurus. Like the front foot, the head does not twist
as the back foot, hips and trunk. Mike refers to the front shoulder,
or where your chin should be before the swing. Ike refers to the
rear shoulder, the position of the chin at the finish of the swing.
Body Stays Centered
With the twisting and weight transfer, the body must stay centered.
The body should not fly forward with the bat head and end up over
the front foot.
Balance and Extension
The arms should be at (or at least near) full extension at contact;
but not before then. Quite often, a hitter will extend their arms
early. This is called casting. If the arms are extended too early,
and the pitch is on the inside half of the plate, the batter must
lean back on their heels to keep from hitting the ball on the bat
handle. The result is a loss of balance backwards, which results
in the batter catching his balance with a small step back, usually
with the front foot
At the completion of a swing, the weight on the front foot should
be centered on the ball of the foot, in a very wide stance, leaving
the batter in a good balanced position. Also upon extension, and
through contact with the ball, the bat head should be flying toward
the pitcher, and not immediately whipping around the batter.
In order to stay balanced, extend properly, and swing through the
ball, the elbows need to stay bent and close to the body. Keeping
the hands "inside" the ball, the bat should be gripped
with fingertips, not the palm, and the middle knuckles should be
nearly aligned, which in turn keeps the wrists aligned and acting
together to snap the bat at the ball.
