Scorecard and ball-by-ball details

Openers KL Rahul and Shikhar Dhawan capitalised on vastly improved batting conditions, both overhead and underfoot, to lead India's recovery on the fourth day in Kolkata. After Rangana Herath's third Test fifty had propped up Sri Lanka's lead to 122, there was only one likely winner. But after Dhawan struck a 116-ball 94 and Rahul hit an unbeaten 73, there were none.

Mohammed Shami, on his home ground, rattled through Sri Lanka's middle order to finish with four wickets, while Bhuvneshwar Kumar added two wickets on the fourth day to return 4 for 88, to bowl Sri Lanka out for 294. With Umesh Yadav also taking two wickets, this was the third time India's seamers took all ten wickets in a Test innings at home, and the first since 1983-84.

Rahul and Dhawan then replied with aggression that has typified their recent Test run. Sunny overhead conditions and a surface that seemed to have settled down helped drastically.

On most pitches, a slightly fuller-than-good length is ideal. But Lahiru Gamage bowled on either side of that, dishing out three half-volleys to Rahul in his first over, which were punched for three boundaries through mid-off. He compensated with a shorter length thereafter, erring in Dhawan's wheelhouse, who cut and pulled gleefully.

In Kolkata's humidity, Dinesh Chandimal was quickly forced to turn his spinners. With no turn, it played nicely into the openers' hands. Rahul nudged and nurdled, opening and closing the bat face to accumulate runs, while Dhawan was more expansive, often using his feet to loft the ball straight.

Herath, Sri Lanka's second-innings star, was taken apart. In 29 overs, India had wiped out their deficit, and undone more than three days of diligence from Sri Lanka.

With Dhawan on 94 and fading light closing in, he committed the only two mistakes of his innings on the same delivery. He drove loosely at Dasun Shanaka, but an inswinger found his inside edge. He reviewed immediately, and replays showed a sharp spike as ball passed bat. India finished the fourth day at 171 for 1, with a lead of 49. Cheteshwar Pujara, who finished unbeaten on 2, could become the ninth batsman to bat on all five days of a Test.
