Featuring "The effect of seam orientation on the flight of a baseball": https://doi.org/10.1103/APS.DFD.2019....

The understanding of aerodynamics in baseball has, over the history of the game, been continuously evolving. This video demonstrates some of the complex behaviour inherent in baseball flight due to the irregular seam locations on the ball and how additional forces, beyond those due to spin and gravity, can play a major role in determining the baseball's flight path.
