DRS debut day in India: How players fared

Under the previous DRS conditions, for a not-out lbw decision to be overturned, the ball needed to have hit the pad well in line with the stumps and the projection needed to show the ball pretty much crashing into the stumps.

India did not get its first Decision Review System (DRS) appeal in a home Test match right, but England’s middle order batsman Joe Root was probably lucky to have survived. The Indians appeared to be quite confident that Root was leg before to Umesh Yadav, but umpire Kumar Dharmasena’s original decision (not out) stayed even after the referral.

The new rule that came into existence in September 2016 says: "Under the previous DRS conditions, for a not-out lbw decision to be overturned, the ball needed to have hit the pad well in line with the stumps and the projection needed to show the ball pretty much crashing into the stumps. Now, for such decisions to be overturned, more than half the ball still needs to hit the pad in line with the stumps, but not as much as before, and more than half the ball still needs to hit the stumps, but not as centrally as before."

England debutant Haseeb Hameed also got it wrong when he was given leg before to Ravichandran Ashwin. The mistake he did was not to consult his partner Joe Root. England would have saved a DRS appeal if Hameed had talked it over with Root. But the 19-year-old was spontaneous in his decision-making process; he made the gesture and appealed.

England captain Alastair Cook decided to walk once given out. He did speak to Hameed and it’s not known what exactly transpired, but Cook walked when it actually seemed like the left-arm spinner Ravindra Jadeja’s delivery (that struck Cook on the outside of his front foot pad) would have missed the leg stump.
