India chased down the target of 217 runs in just 28.5 overs.
India beat Sri Lanka by nine wickets in the opening One-day International of the five-match series in Dambulla on Sunday.
Opting to field, India bundled out Sri Lanka for 216, and then chased down the target of 217 with as many as 127 balls to spare. Shikhar Dhawan scored 132 off 90 balls while Virat Kohli made 82 off just 70 balls.
India carried its domination from the Test series into the One-day format and achieved its biggest ever win in terms of overs left while chasing a 200-plus total.
Dhawan punished the bowlers with 21 boundaries, including three sixes, finishing the match in a jiffy. He brought up his 11th ODI hundred off only 71 balls and it was the second quickest hundred against Sri Lanka by an Indian batsman after Virender Sehwag's 66-ball effort at Rajkot in 2009.
The left-hander raised an unbeaten 197-run partnership for the second wicket with skipper Virat Kohli, who scored 82 off 70 balls.
Chasing a paltry 217, India did not make the best of starts as Rohit Sharma (4) was run out in the fifth over when he lost his bat and did not ground his feet behind the crease to beat Chamara Kapugedara's throw.
But Dhawan batted like he had been throughout this trip and put the Lankan attack to the sword once again. With Kohli for company, he brought up India s 50 in the ninth over and after the first powerplay, the visitors were placed at a comfortable 64 for one.
Their 50-run partnership came off only only 38 balls.
While Dhawan played some attacking strokes, Kohli was content with rotating strike. They never looked at any discomfort during their stay at the crease together, and indeed Sri Lanka did not look like breaking this partnership either.
Dhawan reached his half-century off 36 balls, inclusive of eight fours and a six. He did not slow down thereafter either and kept attacking the Lankan bowlers with their partnership crossing the 100-mark in 78 balls.
The opener, though got a life on 88 in the 21st over off Vishwa Fernando with keeper Dickwella diving full stretch to his left but unable to pouch the edge.
At the other end, Kohli scored his 44th ODI half-century off 50 balls, inclusive of six fours. The Indian skipper accelerated thereafter, scoring 32 off only next 20 balls, with another 4 fours and a six.
Dhawan was again dropped off Lasith Malinga in the 26th over at long on as Lankan shoulders dropped. The hosts were soon put out of their misery as India won with 21.1 overs to spare.
Earlier, Sri Lanka frittered away a promising start losing nine wickets for 77 runs after Niroshan Dickwella (65) and Danushka Gunathilaka (35) gave the hosts a solid start with a 74-run stand. After the openers' dismissal, Sri Lanka went on a self destruction mode to be all out in 44th over from a solid 139 for one.
Left-arm spinner Axar Patel, playing his first international match since October last year, was the stand out bowler for India with a career-best figures of three for 34 runs in 10 overs.
Sri Lankan fans turned up at the venue expecting an improved showing from the meek surrender in the preceding Test series but they were left disappointed, at least on the batting front. The home team's ordinary batting show came after Virat Kohli won a fourth-consecutive toss on this tour and opted to field.
India opted to go in with left-arm spinner Patel and leg spinner Yuzvendra Chahal as Kuldeep Yadav was surprisingly left out.
Sri Lanka openers Gunathilaka and Niroshan played out the first five overs calmly, testing out the opening pair of Bhuvneshwar Kumar (0/33) and Jasprit Bumrah (2/22). Dickwella later played some attacking shots as Lanka reached 55/0 in the first ten overs. Their 50-partnership had come off 53 balls, and they looked good for a long vigil at the crease as India were bereft of ideas to break their stand. Dickwella reached his 5th ODI half-century off 65 balls.
But things started happening when the spinners, particularly Kedar Jadhav (2/26), came on to bowl. In the 14th over, Dickwella survived a run-out attempt with a dive, but then in that same over, Gunathilaka perished playing a needless reverse sweep off Chahal (2/60).
Kusal Mendis (36) then played some attractive strokes and put on 65 runs with Dickwella as they looked to attack the Indian spinners. Jadhav though trapped the opener lbw in the 25th over, with the batsman not surviving the DRS review either.
The big blow came when Patel bowled Mendis against the run of play in the 28th over, with the scorecard reading 150/3 at that stage. Lanka still looked good to reach 280 at that stage, but the spinners strangled the runs and collapse came expectedly thereafter. First, skipper Upul Tharanga (13) got off a horrendous full toss from Jadhav in the 33rd over and was caught at long on. In the next over, Kohli ran out Chamara Kapugedara (1) with a straight hit from extra cover.
In the same passage of play, Bumrah cleaned up Thisara Perera (0) with a beautiful yorker and Lanka s hopes of a challenging total all but vanished. Patel accounted for Waninda Hasaranga (2) and Lakshan Sandakan (5) to dismiss any fightback from the lower order. It was his best effort in ODI cricket, going past 3/39 against South Africa in Indore (2015). Lasith Malinga (8) put on 22 runs with Angelo Mathews (36 not out) for the ninth wicket as they pushed the Lankan score past 200. But the former departed in an attacking manner, stumped off a wide delivery from Chahal as the Lankan innings crossed the 40-over mark. They didn't last long however, despite Mathews best efforts, with Bumrah cleaning up Vishwa Fernando (0) in the 44th over to bring another hapless showing from the hosts to an end.
Virat Kohli won the toss and opted to chase. Lasith Malinga, playing his 200th ODI, returned for the hosts. Left-arm seamer Vishwa Fernando was given his ODI cap. Bhuvneshwar Kumar and Jasprit Bumrah were back to lead the seam attack for India while Axar Patel and Yuzvendra Chahal were given the charge in the spin department.
Brief scores:
Sri Lanka: 216 all out in 43.2 overs (Niroshan Dickwella 64, Kusal Mendis 36, Angelo Mathews 36 not out; Jasprit Bumrah 3/34, Axar Patel 3/34)
India: 220 for one in 28.5 overs (Shikhar Dhawan 132 not out, Virat Kohli 82 not out).
