Reverse swing
Reverse swing makes the ball curve toward its shiny side late in flight.
Reverse swing is a bowling technique in cricket where the ball swings in the opposite direction to conventional swing—towards the shiny side rather than the rough side. It occurs when the ball becomes worn, typically after around 50 or more overs, and is rarer than orthodox swing. Reverse swing tends to be stronger than normal swing and often occurs late in the ball's trajectory, making it particularly difficult for batters to defend against.

Lore & Background
Reverse swing was pioneered by Pakistani fast bowlers. According to the ex-chairman of the Pakistan cricket board, Shaharyar Khan, the technique was invented by Saleem Mir, who played for the Punjab Cricket Club in Lahore during the late 1960s and taught it to his teammate Sarfraz Nawaz. Sarfraz Nawaz introduced reverse swing into international cricket during the late 1970s, and passed their knowledge on to Imran Khan, who in turn taught Wasim Akram and Waqar Younis.
Reader's Guide
Reverse swing is significant because it offers a potent weapon for fast bowlers, especially in Test matches when the ball is older. It can reverse the expected direction of swing, so a natural outswinger becomes an inswinger and vice versa. This unpredictability, combined with its late movement, often leaves batters committed to the wrong line. Two consecutive deliveries from Wasim Akram, one of each type, were considered the turning point of the 1992 World Cup Final. Bowlers try to disguise the direction of reverse swing by running up starting with the opposite hand before switching hands and covering the ball as long as possible before release. The technique has also been associated with ball-tampering controversies, as teams have allegedly tried to alter the ball illegally using materials such as sandpaper to produce additional swing.

Frequently Asked Questions
What is reverse swing in cricket?
Reverse swing is a bowling technique in which the ball curves toward its shiny side instead of the rough side, the opposite of conventional swing. It is also called contrast swing and is closely associated with Pakistani fast-bowling tradition.
How does reverse swing actually work?
Once the ball has worn down—typically after around 50 overs or more—the polished side causes airflow to separate from the ball earlier than on the scuffed side. That asymmetry pushes the ball laterally toward the shiny side, especially when delivered at speeds above 90 mph.
Who are the most famous reverse swing bowlers?
Pakistani fast bowlers such as Imran Khan, Wasim Akram, Waqar Younis, and Sarfraz Nawaz are widely credited with perfecting the art. English bowlers Andrew Flintoff and Simon Jones are also frequently cited for their reverse swing ability.
Why is reverse swing harder to face than orthodox swing?
The lateral movement kicks in much later in the ball's trajectory, leaving batters very little time to adjust their shot. The turn is also generally sharper and more pronounced than normal swing, making it especially punishing to defend against.
What conditions are needed for reverse swing to work?
The ball must be sufficiently worn so one side is clearly rougher than the other, usually past the 50-over mark. The bowler also needs to generate high release speed, generally over 90 mph, for the airflow difference to produce meaningful swing.
