What is the reverse swing in cricket? How does it differ from the conventional swing? How many of you people used to play and watch cricket? How stupid I’m. In India cricket is a kind of religion. And almost everybody uses to love watching cricket whether he played it or not in his entire life.
One more question, How many of you people aware of one of the most important terminologies in the cricket i.e reverse swing? I’m pretty much sure that in spite of being a regular viewer of cricket but still very few understand it. Isn’t it? Don’t worry, I’m here to help you in understanding the science behind this in a very simple yet effective way. So let’s get started.
What is conventional swing?
First of all, you have to understand the science behind the conventional swing of the cricket ball. Conventional swing generally occurs in great amount when the ball is in new condition and the speed of delivery is around 70-75 mph. The cricket ball has two sides around the seam.
On the shiny side, the velocity flow of air is faster in comparison to the other rough side, so the air flows streamline(laminar) at the shiny side and turbulent at the rough side. So according to Bernoulli’s principle in fluid dynamics, the resultant force pushes the ball towards the rough side. This is conventional swing.
What is reverse swing?
When the ball generally gets old and rough say 20-30 overs old and more and this can be vary depending on the condition of the ball and the pitch. When both the side of the ball has been rough but the bowler and other team members try to maintain one side moist and less rough in comparison to another rough side by applying saliva and sweat.
The air moves turbulently from both the sides but the less turbulent at the moist side in comparison to the more rough side. So the trajectory of the ball changes. Now the ball moves away from the rough side due to resultant force pushes the ball towards the shiny side.
That is reverse swing. To get the reverse swing is very tough in comparison to conventional swing. It demands a lot of practice and hard work to acquire the skill.
Where was it discovered?
According to the various sources such as Wikipedia, It is said that reverse swing discovered in Pakistan and introduced to international cricket in the 1970s.
As everyone already knows that Pakistani bowlers generally masters in this art. Imran Khan, Waqar Younis, Wasim Akram and Shoaib Akhtar are some legendary bowlers who are known as masters of both swings. India also has some great bowlers who could bowl reverse swing. Kapil Dev, Ajit Agarkar, and Zaheer Khan are some well-known names in this category.
Now in the modern day cricket, James Anderson, Mitchell Starc, Md. Amir, Del Steyn, Md. Shami, Umesh Yadav and many more are the popular names who knows the art of both swings.
That’s it guys, I hope now you have understood the science behind the conventional swing and reverse swing. If you want any more clarification, please comment your questions in the comment section.
