IIT professor reveals 'rocket science' behind Bumrah's bowling

IIT-Kanpur professor Sanjay Mittal has attributed 'reverse Magnus force' to Jasprit Bumrah's dominance. He discovered that Bumrah's speed, seam position and rotational speed of 1000 RPM gives 0.1 spin ratio for the ball, which puts it into reverse Magnus effect regime. A downward force on a ball by Bumrah causes it to dip sharply, which batsmen find difficult to pick.
