Hi Sly,

There are an infinite number of planes of the pitch.

This "plane" (a curved surface when gravity and a non-vacuum are present) contains every point that the ball travels during release to catch.

From a hitters perspective, you want your bat head to travel in that same plane (at the same time as the ball) as long as is reasonably possible with maximum bat head speed.

From a pitcher who is throwing junk perspective, you want those planes to have as much curvature in them as possible at whatever velocity the ball is traveling.
