Galle: India closed in on a big win as their domination went uncontested for the third successive day in the first cricket Test against Sri Lanka here.

Virat Kohli (76 batting) and Abhinav Mukund (81) put on 133 runs for the third wicket as India reached 189 for three in 46.3 overs at stumps on a rain-affected day three.

Overall, the visitors have a lead of 498 runs after they decided against enforcing the follow-on.

In reply to India's mammoth first-innings total of 600, Sri Lanka were bowled out for 291 in 78.3 overs.

After a rain-break that cost 86 minutes, playing time was extended until 6pm local time to make up for the lost overs.

Kohli and Mukund made hay while the sun was out as they barely countered any trouble from the Sri Lankan bowlers.

Mukund scored only his second Test half-century off 78 balls, after his previous effort of 62 runs against the West Indies at Roseau in Dominica back in 2011.

He then proceeded to overtake that mark to record his highest score in Test cricket. Overall, he faced 116 balls, and hit eight fours.

At the other end, Kohli overcame his bad patch in Tests by scoring his 15th fifty off 68 balls. This was the first time since February that the Indian skipper had crossed the

40-mark, after scoring 204 and 38 against Bangladesh at Hyderabad. His highest against Australia in five innings across three Tests was 15.

Here, he picked easy runs off the Lankan bowling and overcame that mental hurdle after scoring only three runs in the first innings. Overall, Kohli faced 114 balls, and hit five fours. His 50-partnership with Mukund came up in only 51 balls, and the duo crossed the 100-mark in 120 balls.

The day's play ended when Mukund fell lbw to part-timer Danushka Gunathilaka (1-15). The batsman opted to review, but that decision too went against him.

Earlier, India had reached 56 for two in 16.5 overs in the second innings when rain intervened in the second session of play. Post lunch, Ravindra Jadeja (3-67) brought the hosts' innings to a quick end as he bowled Lahiru Kumara (2).

Dilruwan Perera was stranded on 92 not out, facing 132 balls, inclusive of 10 fours and four sixes. India took a first innings' lead of 309 runs.

Shikhar Dhawan (14) then fell quickly, caught at backward point off Perera (1-20), chasing a wide delivery. He put on 19 runs for the opening wicket with Mukund. He then added 37 runs with Cheteshwar Pujara (15) for the second wicket.

Some 40 minutes before tea, a thunderstorm lashed the sea-facing ground. But Lahiru Kumara (1-53) had enough time to bowl one more delivery and Pujara was caught at leg slip. An early tea was taken to make up for lost time.

In the morning, Perera and Angelo Mathews (83) defied India as Sri Lanka reached 289 for eight at lunch. The two batsmen put on 62 runs for the sixth wicket as the visitors led by another 311 runs.

Starting from overnight 154 for five, Perera and Mathews continued from where they had left yesterday evening and extended their defiant partnership. Umesh Yadav (1-78) and Jadeja got proceedings underway for India, but neither were troubled the duo as they brought up their 50-partnership off 96 balls.
