Input: Reverse swing is an art invented by former Pakistani fast bowler Sarfaraz Nawaz, followed by Imran Khan, Waseem Akram and Waqar Younis.

A new cricket ball has shine on both sides. When the ball gets older the shine disappears and the amount of swing is decreased. In reverse swing the bowler keeps one side of the ball shining and one rough.
Due to air friction the rough side resists the air and the ball moves towards the shining side having less friction on that side.
So it will allways move towards the direction of the shine.
Waqar younis had the habbit of hiding the ball from batsman before its delivery. So that the batsman keeps guessing the direction of the swing.
Output:
How do bowlers get reverse swing in cricket?
