Jasprit Bumrah has a unique action, which he has developed from playing on a ground that did not have space for a long run-up. The short run-up and need to generate pace is what probably resulted in that action and his continuation with it.
While most of us are in absolute awe of the genius that this cricketer is, one IIT professor is more focused on decoding the truth behind Bumrah’s lethality on the cricket pitch.
The fast bowler broke onto the scene in the IPL with Mumbai Indians and has gradually grown into one of the biggest forces of the Indian bowling attack. Proclaimed as the best fast bowler in cricket right now, Bumrah bowls at a consistent pace of 145kmph. He has also warranted for most of India’s success overseas. There is no doubt that he is right at the top of the best bowlers in the world list.
IIT professor of Aerospace Engineering at IIT Kanpur, Sanjay Mittal has dwelled deeper into the secret behind Bumrah’s action. The professor has also claimed that there is a certain ‘rocket science’ behind Bumrah’s action and the success he is gaining.
In the above picture, Figure 1 explains how the movement of the ball and the backspin increase the speed. The movement of the ball causes a thin layer around it called the boundary layer. The key to a fast bowler is the use of Magnus effect and reverse Magnus effect.
As for Jasprit Bumrah, the IIT professor believes that the key to his success is the backspin that is generated by the fast bowler. Due to Bumrah’s unusual action, the ball also follows the reverse Magnus effect and created a dip (as seen in figure 2). This causes an unexpected bounce and works in deceiving the batsman as he cannot gauge the bounce.
Well, whether this is true or not. We know one thing, the science in his bowling is causing havoc in the cricketing world and let’s hope his great form continues through to the ICC World Cup 2019 as well.
