Karnataka Beat Tamil Nadu By VJD Method: Here Is All You Need To Know About VJD System

Karnataka, on Friday, beat Tamil Nadu by 60 runs (VJD) in a rain-affected final to clinch the Vijay Hazare Trophy. Fresh off the fine series against South Africa, Mayank Agarwal starred with the bat for Karnataka. The India Test opener smashed an unbeaten 55-ball 69, while KL Rahul too reached a half-century to put Karnataka on course to their fourth Vijay Hazare title win in the last seven seasons.

Karnataka captain Manish Pandey won the toss and decided to field and his bowlers totally justified the decision. Led by Abhimanyu Mithun, they bowled brilliantly to restrict Tamil Nadu to a modest 252 in 49.5 overs. Mithun, who has played 4 Tests and 5 ODIs for India, was the best performer with the ball as he picked up a fifer including a hat-trick.

In the final over,  Mithun dismissed Shahrukh Khan, M Mohammed and Murugan Ashwin off successive deliveries to become the first Karnataka bowler to complete a hat-trick in the Vijay Hazare Trophy.

For Tamil Nadu, Abhinav Mukund (85) and Baba Aparajith (66) impressed with the bat as they added 124 runs for the third wicket. However, there was little support from the other end and Tamil Nadu ended up with a modest total.

In reply, Karnataka were dealt an early blow when Washington Sundar removed Devdutt Padikkal in the 5th over. However, India stars Rahul and Agarwal joined forces and ensured Karnataka were never really in any danger of losing the final. With rain threat looming large, the two smashed their way past the par score (86 for 1) to down the five-time champions Tamil Nadu by 60 runs.

“It was a top team performance, I am very happy with the way the boys performed throughout the tournament. The mindset of the boys is good, they were excelling in whatever games they played, we are seeing the fruits of their hardwork. We want to keep playing this way going further,” said a delighted Pandey in the post-match presentation.

What is VJD system?

Karnataka beat Tamil Nadu by 60 runs courtesy of VJD system. While the international cricket uses DLS method, India rely on VJD system to find out the result in rain-affected games.  The VJD system was constructed by a civil engineer from Kerala, V Jayadevan and thus its name.

VJD system takes the statistics from previous games and doesn’t take the reputation of the sides or their recent form into account. It offers a more scientific alternative to DLS method and divide the innings into phases. According to Wikipedia, VJD method is essentially built around two curves. The first curve depicts the “normal” run getting pattern; i.e., when there is no interruption and the side is expecting to bat its full quota of overs.

The second curve (“target curve”) indicates how the batting side should “speed up” after an interruption. The “normal” curve takes into account both the percentage of overs played and the percentage of wickets lost. The “target” curve, which is used to set revised targets, only considers the percentage of overs played.

To obtain the normal score curve VJD System considers the percentage of runs scored in seven phases: settling down (first 10% of the overs, i.e. the five overs), exploiting field restrictions (next 20% of the overs, i.e. overs 6–15), stabilising the innings-I (next 20%; overs 16–25), stabilising the innings-II (next 10%; overs 26–30), beginning the acceleration (next 20%; overs 31–40), secondary stage of acceleration (next 10%; overs 41–45) and final slog (last 10%; overs 46–50). The normal score curve is then obtained by fitting a suitable regression equation for the cumulative overs % and the corresponding cumulative runs scored %.

The system obtains the target score by looking at the percentage of runs scored in each of the seven scoring phases. It arranges them in descending order of run productivity, and again obtains a regression fit for cumulative overs percentage versus the juxtaposed cumulative runs scored percentage,
