> The hands are staying relatively flat in relationship to the ground but the bathead is
matching the ball plane. A lower pitch has a greater downward angle then a high pitch so
your bat trajectory is always changing slightly from height of pitch and type of pitch. A
changeup or curve drops more then a fastball. It is impossible to be perfect in matching
every pitch angle but the sooner the batter reconizes the spin (type of pitch) and location
the better chance they have of matching the angle that the ball is coming in on.

pitch angles. There is a reason that a really fast pitcher is overly successful in little league.
Since there ball does not drop as much as slower pitchers the decreased angle makes it
tough for the hitter to get their bathead on plane because they are not as experienced with
making these adjustments.

Hi DaveP,

Thank you for the discussion and your perspective on hitting. You have made some good
points as well.

The only way to get better at something is to practice it, and I believe this discussion room
is a good tool to use to practice the art of coaching.

Thanks again,

Jimmy
