what is reverse swing?

Question

i know inswing ,outswing ,off cutter, leg cutter.but reverse swing can u pls help me

Answer 1

reverse swing is art of swing . when the ball coming old and rough then most of fast bowlers used this art of bowling

this bowlers are master of reverse swing.

Answer 2

Once the ball becomes older and more worn, it will begin to move in the opposite direction to where it would usually swing with no great change in the bowling grip.



For example, an outswinger's grip will move towards the batsman in the air while an inswinger will move away from the bat.



All this tends to happen very late on in the delivery, making it difficult for the batsman to pick up the changes in the air.



Not every single bowler can obtain reverse swing - the ball needs to be propelled above 80mph or thereabouts to make it move in the air.

Reverse swing is all to do with the deterioration of the ball and the seam position in flight.



As the ball becomes rougher, it will take on a different characteristic as it deteriorates.



So if you present the ball as an outswinger, the ball has deteriorated so much on the rough side that it takes on the characteristics of the shiny side.



Which means a natural outswinger will become an inswinger and conversely, an inswinger into an outswinger.

Answer 3

Reverse swing is the one when the ball moves in opposite direction of the shiny and heavy side very late !

There is a scientific phenomenon of aerodynamics behind it . Have you seen aeroplanes take off from the ground, the wings are shaped in such a way that the surface area is different on the lower side of the wing than the upper side of the wing giving it aerodynamic lift due to pressure differential based on velocity difference and that is what is aerodynamics of different surface area on both sides of ball !

It is called a Bernoulli's theorem in technical words !



Conventional swing happens when the seam gives a different surface on the side of seam causing a movement towards the seam however when the ball gets old, the seam gets subdued and one side is ruffed up and one side is shined consistently by fielders , it gives more surface area on the rough side and hence more velocity causing a same effect but in the opposite side of the shine and this is reverse swing !



hope it helps!

god bless!

Answer 4

Swing bowling is a technique used for bowling in the sport of cricket. Practitioners are known as swing bowlers. Swing bowling is generally classed as a subtype of fast bowling. The founder of reverse swing is Pakistani bowler Sarfraz Nawaz in late 1970's.



The essence of swing bowling is to get the cricket ball to deviate sideways as it moves through the air towards or away from the batsman. In order to do this, the bowler makes use of four factors:



The raised seam of the cricket ball

Asymmetry in the ball caused by uneven wear of its surface

The speed of the delivery

The bowler's action

The asymmetry of the ball is encouraged by the constant polishing of one side of the ball by members of the fielding team, while allowing the opposite side to deteriorate through wear and tear. Over time, this produces a marked difference in the aerodynamic properties of the two sides.



At speeds around 80 mph (around 130 km/h), the airflow around the ball is in transition between smooth, or laminar flow, and turbulent flow. At speeds of 90 mph (around 145 km/h) and above, all the flow is turbulent. A medium-pace bowler, working at 75 to 80 mph (around 120 to 130 km/h), takes advantage of this. In this critical region, the raised seam and other minor imperfections in the ball's surface can induce turbulence while air flowing over other parts of the ball remains laminar. Turbulent air separates from the surface of the ball later than laminar flow air, so that the separation point moves to the back of the ball on the turbulent side. On the laminar flow side it remains towards the front. The result is a net force in the direction of the turbulent side.



Thus by keeping the seam and roughness to one side, the bowler induces the ball to swing in that direction. Skilled bowlers can even make a ball swing one way, and then 'break' the other way upon bouncing, with an off cutter or leg cutter hand action.



The swing of a cricket ball is not caused by the Magnus effect, which gives rise to a force perpendicular to the axis of rotation (in this case up or down). The deviation of a swinging cricket ball is parallel to the axis of its rotation.

Answer 5

Normal swing occurs mostly when the ball is fairly new. As it wears more, the aerodynamics of the asymmetry change and it is more difficult to extract a large amount of swing.



When the ball becomes very old—around 40 or more overs old, it can begin to swing towards the polished side rather than the rough side. This is known as reverse swing (Andrew Flintoff and Simon Jones have been known to produce reverse swing in balls as young as 15 overs old[3]). In essence, both sides have turbulent flow, but here the seam causes the airflow to separate earlier on one side. The result is always a swing to the side with the later separation, so the swing is away from the seam. (See External Links.)



Reverse swing is difficult to achieve consistently, as it relies on uneven wear of the ball, tends to occur mostly in hot, dry weather conditions, and requires bowling at high speed. Normal swing can be achieved at relatively moderate bowling speeds, but only the fastest bowlers can regularly produce reverse swing.



Reverse swing tends to be stronger than normal swing, and to occur late in the ball's trajectory. This gives it a very different character from normal swing, and because batsmen experience it less often, they generally find it much more difficult to defend against. It is also possible for a ball to swing normally in its early flight, and then to reverse as it approaches the batsman. This can be done in two ways: one for the ball to reverse in the opposite direction to the original swing, giving it as "S" trajectory; and the other for it to reverse in the same direction making the swing even more pronounced. Either way it can be very devastating for the batsman: in the first instance, he is already committed to playing one way, which is often the wrong way to play swing in the opposite direction; and in the second instance, his stance will have conformed to dealing with the degree of expected swing and could leave him vulnerable to being caught behind, LBW or bowled. Two back to back deliveries from Wasim Akram, one of each type, were considered to be the turning point of the 1992 World Cup Final.



Controversy regarding reverse swing has never left modern cricket, as the Pakistani team was accused of ball tampering by the controversial Australian umpire Darrell Hair during the fourth test against England in 2006 when the ball began to reverse swing after the 50th over.[citation needed] His co-umpire Billy Doctrove fully supported him in this action. A hearing subsequently found that there was insufficient evidence to convict anyone of ball tampering.
