From what I can gather, as the ball deteriorates the rougher side of the ball, at speeds in excess of 80 mph actually travels faster through the air and swings against the known direction which is normally away from the shiny side! Howzat then you aerodynamics gurus? Did the Ruskies beat up their capsule or something?
Does this have ANYTHING to do with the shark skin rudder that Airbus patented a decade or so ago?
