This was a talk I gave at the New England American Physical Society (APS) Meeting in Boston on March 17, 2018. I argue that one should keep time as well as position even for Newtonian calculations. While its role is dull in classical calculations, it forms a structure consistent with doing special relativity, a good thing Space-time symmetries can be explored using animations. Reflections in space are done with mirrors. Reflections in time are done with animations. Reflections in space and time look like the ball continues its path. Space is orthogonal to time in that drawing in space is separate from animating in time. Slides are available at http://bit.ly/vp-baseball
