PS - you briefly mentioned seams. You also said non-spinning. A non-spinning non-spherical object (such as a baseball with seams) WILL behave in odd ways. It is similar to lift, but not in the way you're mentioning. So, a knuckleball, for example, CAN rise. (A bowling ball without holes, thrown with no spin at a similar speed as a knuckleball would NOT behave like a baseball knuckleball).
However, I don't think that was anyone's argument (yours or the other side's). We were talking about a fastball, which does spin. And it is spin which causes the movement of a baseball (ask anyone who has seen a curveball. Have you seen one?)
