I do not understand how one can mentally compute the moment of collision between a spheroid 228.60–234.95 mm in circumference and having a mass of 141.75 to 148.83 g. moving at 152.9–169.14 km/h (the usual speed) in a 1 g. field (and even ignoring air friction) in a time frame such that it can be struck by a object no more than 1,100mm in length, massing no more than 1 kg. and having a diameter of not more than 70mm at the thickest part after traveling over a distance in a distance of 18.3 meters. This is especially difficult when the object to be struck will itself be traveling in an arc -- but see Fortenbaugh's The Biomechanics of the Baseball Swing (Dissertation, U. of Miami, 2011) for a much more complete discussion of this.
