The Secret Behind Jasprit Bumrah’s Deadly Slower Balls: How an Unorthodox Action Changed Fast Bowling
Jasprit Bumrah is considered one of the most feared fast bowlers of this era of cricket. His unorthodox action coupled with his skill and accuracy has made him a nightmare for batsmen across the globe. What was once considered unorthodox has now turned out to be his biggest strength. Bumrah’s ability to use his slower balls effectively has been instrumental in India’s success in the 2026 T20 World Cup. In this blog, we would try to understand how his unorthodox action has given cricket some of its most lethal slower balls.
The Birth of an Unusual Bowling Action
Jasprit Bumrah’s bowling action is not new to anyone in the cricket world. Unlike other fast bowlers, who take a long run and bowl with a smooth action, Bumrah’s short run and stiff bowling action have been a topic of discussion since his early days as a cricketer. When Bumrah joined the academy of a famous coach, Kishore Trivedi, in Ahmedabad, many believed that Bumrah’s bowling action looked unusual and that it could also be illegal. But Trivedi saw the young cricketer and understood that his bowling action was not only legal but also worked in his favour. Instead of forcing Bumrah to change his bowling action, Trivedi took a courageous decision to let Bumrah bowl in a way that he felt most comfortable bowling. It is believed that this decision proved to be a turning point in Bumrah’s career. Changing a cricketer’s bowling action is not a small thing, and it can affect a cricketer’s rhythm and confidence. Trivedi’s decision to let Bumrah bowl in his own way allowed him to work on his bowling skills and develop accuracy, deadly Yorkers, and variations like slower balls. Over time, Bumrah became more accurate with his aim, perfected his deadly Yorkers, and mastered variations like slower balls. What was once unusual for Bumrah became one of the most recognizable actions in world cricket.
Why Bumrah’s Action Confuses Batters
One of the major reasons behind Bumrah’s success is his unorthodox style of delivering the ball, which often confuses the batter and goes against his timing. The length of his run-up is quite short compared to other bowlers, and it seems more like a casual walk before he starts sprinting. The change in his pace is quite dramatic, and this often catches the batter off guard. Furthermore, he releases the ball quite ahead of his head, which also gives less time to react to the bowler. A little less time can make a huge difference considering he is delivering the ball at a high speed of 145 km/h. The alignment of his wrist and body at the moment of delivering the ball is another reason behind his success. Since his style is not exactly perfect, it often becomes difficult for the batter to understand his changes. The speed of his arm is quite consistent, whether he is delivering a quick ball or a slower one. This often puts the batter in a state of confusion, and this hesitation often proves to be costly for them.
Why Bumrah is so good at doing dangerous slower balls?
In T20 cricket today, fast bowlers use the slower ball as a primary weapon. Bumrah has an ability unlike anyone else to execute this shot perfectly. Instead of using just one type of delivery, he has several different variations available to him, including an off-cutter. This is achieved by his fingers running across (along) the ball when he releases his hand from the grip, making the ball have less speed. He also uses a slight flick of his wrist when releasing the ball to change the way the ball spins (rotates) and therefore create more confusion. Also, because his arm speed on the slower ball looks almost exactly like his fast (??) delivery arm speed, batters get fooled when trying to predict the speed of the slower ball. The other reason his slower balls are so different than everybody’s is that he changes (mixes) lengths. At times he bowls his slower balls into the pitch, so the ball grips the surface and comes in to the batter later than they expect it to. Other times he bowls his slower balls full and tries to tempt batters with an early (or too early) launch. At the 2026 ICC Men’s T20 World Cup, his different (various) slower balls were vital for dismissing several key batters and limiting runs during crunch (pressure) moments in games.
From Academy Prospect to India’s Ultimate Death-Over Weapon
The story of Bumrah’s transition from an academy prospect to India’s ultimate death-over bowler is one of hard work and practice over a long period of time. Having mastered the art of accuracy and swing in his younger days as an academy prospect, he has over time honed his skills to deliver under pressure. The final overs are usually the toughest part of limited-over cricket, especially T20 matches. The batsmen are usually aggressive in their approach, and it is here that even a minor mistake can prove costly in terms of runs conceded. Yet again, Bumrah has shown his mettle as a bowler who can control the end overs of a T20 match. The reason behind his success in delivering under pressure is his repertoire of skills and his ability to understand the game perfectly. He knows exactly what the batsman is trying to do and adjusts his strategy accordingly. In high-pressure tournaments such as the 2026 ICC Men’s T20 World Cup, he emerged as India’s ultimate bowler. What started as an unorthodox style of bowling in a small academy has today become one of the most feared styles of bowling.
Conclusion
To sum it all up, Jasprit Bumrah’s success is a perfect example of how uniqueness can be a strength when it comes to sports. While his bowling style may have looked unconventional at first, it is safe to say that it is now his biggest strength. With the guidance of his mentor Kishore Trivedi, who recognized his talent at an early age, Bumrah has managed to hone his skills without compromising his natural style. It is safe to say that his lethal slower balls and ability to deliver under pressure have made him one of the feared fast bowlers of world cricket.
