We consider the impact of drag force and the Magnus effect on the motion
of a baseball. Quantitatively we show how the speed-dependent drag coefficient
alters the trajectory of the ball. For the Magnus effect we envision a scenario
where the rotation of the ball confines the Magnus force to the vertical plane;
gravity, drag force and the Magnus force make a trio-planar system. We
investigate the interplay of these forces on the trajectories.
