I have seen rotational hitters develop a "hole" in their swing that
results in strikeouts, pop-ups or the ball driven into the ground. The hole manifests itself as a downward swing followed by an upswing finish. If you look at your swing, it should be on one plane throughout - roughly the same plane as your shoulders.

If done correctly, rotational hitting will get the bat onto the same
plane as the ball flight sooner and keep it there longer than linear
hitting. This results in a greater chance for solid contact and more
consistent results. A linear swing is usually taught with the idea of
keeping the bat head above the hands until contact with the thought
that the swing path of the bat head will create backspin on the
baseball and allow it to carry further. Of course, there is less bat
head speed (which is power!) and less chance of contact than with
rotational...
