IIT-Kanpur professor decodes Jasprit Bumrah's unconventional bowling action

Bumrah's speed, seam position and rotational speed of 1,000 RPM gives 0.1 spin ratio for the ball, which puts it into reverse Magnus effect regime, states the IIT professor

He grabbed the limelight after scalping the wicket of Virat Kohli in Indian Premier League (IPL) 2013. Three years later, he donned the blue Indian jersey for the first time and since then; there has been no looking back for young Jasprit Bumrah. Recently after Mumbai Indians’ fourth IPL win, former Indian batting legend Sachin Tendulkar termed him as the ‘best bowler’ in the world. His bowling skills in the death overs are unmatched and even, the Indian skipper Virat Kohli would be counting on him in the upcoming ICC Cricket World Cup. Meanwhile, an IIT-Kanpur professor, Sanjay Mittal has decoded the secret behind Bumrah’s success that also includes his unconventional bowling action. ‘Reverse Magnus Force’ – the reason that has made Bumrah one of the most-lethal bowlers of the world. Mittal, in one study, has said Bumrah's speed, seam position and rotational speed of 1,000 RPM gives 0.1 spin ratio for the ball, which puts it into reverse Magnus effect regime. “A downward force on a ball by Bumrah causes it to dip sharply, which batsmen find difficult to pick,” Mittal was quoted as saying by www.inshorts.com. With a unique action, Bumrah will be key to India's chances in the upcoming World Cup with many experts believing the 25-year old pacer will make all the difference. Bumrah recently helped Mumbai Indians win a record fourth Indian Premier League title. The Ahmedabad-born quick has so far taken 82 wickets in 77 IPL matches, 85 wickets in 49 ODIs, 49 wickets in 10 Tests and 51 in 42 T20Is.
