It is now two wins in two for Afghanistan, who enjoyed another impressive opening stand as Rahmanullah Gurbaz plundered 80 off 56 balls, including five fours and five boundaries, with Ibrahim Zardan adding 44.
Azmatullah Omarzai's dismissal for 22 saw Afghanistan stumble, but with a respectable 159-6, it was always going to be hard for New Zealand to chase.
The 2021 runners-up could not find their footing, with only two of their players reaching double figures – Glenn Phillips top-scored with 18.
They stumbled to 75 all out in just 15.2 overs, suffering their first T20 international defeat to Afghanistan, and they drop to the bottom of Group C.
Elsewhere, Bangladesh survived a scare to make a winning start to their campaign, getting a two-wicket victory over Sri Lanka in Dallas.
Pathum Nissanka impressed with 47 off just 28 balls, but a flurry of late wickets saw Sri Lanka stumble to 124-9 after a strong start.
Bangladesh’s chase started poorly, with both openers being dismissed in the first two overs. However, after Towhid Hridoy's 40, and Liton Das' 36, Mahmudullah's 16 not out helped them over the line at the end of the 19th over.
Data Debrief: Dominant Afghanistan strike again
Afghanistan have opened an ICC Men's T20 World Cup campaign with back-to-back wins for just the second time, last doing so in 2016. They have now won their last four T20Is, their longest streak since 2022.
Gurbaz hit 50 for the second game in a row, improving on his 76 runs in their win over Uganada with 80 in this win.
The Kings, after winning the toss and batting first, posted 177-7 from their 20 overs.
Avishka Fernando was the main contributor for the three-time champions with 59 from 48 balls while Pathum Nissanka hit 51 off 33 balls.
Fernando’s innings included seven fours and a six while Nissanka hit six fours and two sixes.
Captain Charith Asalanka also contributed a 15-ball 33 against 3-34 off four overs from Zahoor Khan and 2-23 from four overs from Dwayne Pretorius.
The Marvels then used all of the 120 balls available to them to successfully chase down their target.
Alex Hales led the way with 65 off 47 balls including seven fours and two sixes while Captain Niroshan Dickwella made 47 off 27 balls including eight fours and a six as Galle reached 179-5 off 20 overs.
Janith Liyanage also made a crucial 13-ball 25 for Galle. It eventually came down to them needing three runs off the last ball, a ball that Sahan Arachchige hit for four to seal the win.
Fabian Allen took 2-33 from his four overs for the Kings.
Full Scores:
Jaffna Kings 177-7 off 20 overs (Avishka Fernando 59, Pathum Nissanka 51, Charith Asalanka 33, Zahoor Khan 3-34, Dwayne Pretorius 2-23)
Galle Marvels 179-5 off 20 overs (Alex Hales 65, Niroshan Dickwella 47, Janith Liyanage 25, Fabian Allen 2-33, Avishka Fernando 2-40)
Charith Asalanka was the hero for Sri Lanka in Colombo, taking two wickets in the space of two balls to bowl India out for 230.
Pathum Nissanka (56) and Dunith Wellalage (67) led the way for Sri Lanka with the bat, propelling them to 230-8 from their 50 overs, with the pair plundering 18 boundaries between them.
India looked well set for the first 12 overs, until the dismissal of Shubman Gill (16) kick-started a mini-capitulation, with captain Rohit Sharma (58), Washington Sundar (five), Virat Kohli (24) and Shreyas Iyer (23) following in quick succession.
KL Rahul and Axar Patel appeared to have steadied the ship, but Wanindu Hasaranga (3-58) and Asalanka (3-30) struck in the space of seven deliveries to drag Sri Lanka back into it.
And the day ultimately belonged to Asalanka who, after being hit for four by Shivam Dube (25) in the 48th over, hit back with a pair of LBWs to leave the tourists stunned.
Data Debrief: India's dominance ended
India had won each of their last six ODIs against Sri Lanka, their joint-longest winning streak against them in the history of the format (along with a run between July 1998 and May 1999), but for the first time since a loss in Colombo in July 2021, they failed to get the job done.
This match did see the two form teams in ODIs take each other on. India (27) and Sri Lanka (22) have won more 50-over games than any other teams since the start of 2023.
At the close of play, Karunaratne, who was dropped on 14 by Jermaine Blackwood, is on 132 and De Silva on 56. Together they have so far put on 97 for the fourth wicket as Sri Lanka eye a massive first innings total on Monday.
After winning the toss and choosing to bat, Sri Lanka got off to a slow start but gradually built momentum throughout the day.
Karunaratne and Nissanka opened the batting and crept to 61-0 without loss at lunch. The 50 partnership came off 132 balls as the home side took a more cautious approach against the West Indies bowling led by Shannon Gabriel.
The partnership would endure until after the interval when Gabriel induced an edge from Nissanka, who was caught at slip by Rahkeem Cornwall for 56 and with the score at 139.
The West Indies would make further inroads fairly quickly afterwards when at 164-1, Roston Chase dismissed Oshado Fernando for three and then at 170-2 removed Angelo Matthews also for three.
However, that was the last success the West Indies bowlers would have for the remainder of play.
Gabriel has so far taken 1-56 from 12 overs while Chase has 2-42 from 17.
Joe Root's record-equalling 33rd red-ball century had ensured England ended a difficult opening day with a chance to build a commanding lead, and they did just that early on as Atkinson took centre-stage.
Resuming at 74 not out, Atkinson brought up his maiden Test century with a fine drive past mid-on shortly before lunch, eventually ending his knock with 14 fours and four sixes.
He would later fall for 118 to the outstanding Asitha Fernando, who then completed a five-for by removing Olly Stone to wrap up the England innings at 427 all out.
Any hopes Sri Lanka had of making an early dent in that target were frustrated, however, as England shared the wickets around in a brilliant team bowling performance.
Chris Woakes and Stone, who removed Dimuth Karunaratne and Pathum Nissanka within the space of five balls – left the tourists teetering at 35-3 by the end of the 10th over, and there was little help to come from the middle order.
Matthew Potts took the ball and sent stumps flying to account for Angelo Matthews and Dhananjaya de Silva in the 21st over, with Woakes, Stone and Atkinson later also doubling up as the tourists collapsed.
Kamindu Mendis' steady knock of 74 off 120 balls brought some respite for Sri Lanka, but he edged Atkinson's delivery into the palms of Woakes for the final wicket, failing to match his ton from the first Test at Old Trafford on a miserable day for the visitors.
England then avoided any drama when taking up the bat for seven overs before stumps, and Ben Duckett (15) and Pope (2) will resume at the crease on Saturday, hoping to make their handsome lead an unassailable one.
Data Debrief: Atkinson's big moment
While Root's heroics put England in a decent position ahead of Friday's play, Atkinson's brilliant 118 – coming off 115 balls – could prove the difference in this Test, allowing England to build a strong lead despite a lack of support from the lower order.
Atkinson's previous best red-ball knock was a score of 21 not out versus West Indies at Trent Bridge in July.
The pair added a record 179 for the sixth wicket and Nissanka became the first Sri Lankan to make a century away from home in his first match. He eventually fell to a catch by Kemar Roach from the bowling of off-spinner Rahkeem Cornwall, who ended with 3-137 off a marathon 42.5 overs.
Roach had the best figures of 3-74 off 27 overs to end the match with six wickets – following up his 3-47 off 16 overs in the first innings.
This left the West Indies with a victory target of 375. They reached 34-1 at the close and will require another 341 to win on the final day with nine wickets in hand. Nkrumah Bonner will resume Thursday on 15 not out and with him captain Kraigg Brathwaite on eight not out.
The match resumes on Thursday at 10 am (9 am Jamaica Time).
The Sri Lankans resumed play at 136 for 3 but the promising partnership of Dinesh Chandimal (44) and Dhanajaya De Silva (39) was halted in its tracks during the morning session. Chandimal was tempted into an attempted hook shot by Shannon Gabriel and caught at deep square leg.
De Silva was given lbw on a delivery from part-timer Jermaine Blackwood, which seemed to be turning away from the stumps. The decision was, however, not appealed.
The rain repeatedly interrupted play after lunch but there was still time for all-rounder Jason Holder to account for Niroshan Dickwella (21), who was caught behind from an inside edge. Suranga Lakmal did not stick around long as he lasted for 9 deliveries before being caught at mid-on by Kraigg Brathwaite off Alzarri Joseph. Dushmantha Chameera became the eighth wicket to fall, after tea, when he was caught by Joshua Da Silva off Holder but Nissanka dug into to reach to within one of a half-century and will resume tomorrow with Lasith Embuldeniya, who is scoreless.
The rain meant that, overall, only 42 over of play were possible at the Sir Vivian Richards Stadium.
Root, who equalled Alastair Cook's record during the first innings of the second Test, made 103 from 111 balls for his 34th Test ton.
England resumed on 25-1 at the start of day three, with Root leading the way for the hosts and the crowd rose as one when a sweeping four completed his landmark century.
He helped his nation set their opponents a target of 483 after they were 251 all out.
As the light faded over Lord's, so too did Sri Lanka's momentum in their record-attempting chase, with Gus Atkinson and Olly Stone claiming Nishan Madushka and Pathum Nissanka respectively.
Play was eventually halted due to bad light, and called off to be resumed on Sunday with the tourists at 53-2 with Dimuth Karunaratne (23) and Prabath Jayasuriya (three) at the crease.
Data Debrief: Root revels on record-breaking day
Day three of the second Test belonged to Root, whose century was also his quickest in Test cricket.
Adding to his 143 in England's first innings, he registered two tons in a match for the first time, while becoming only the fourth player to achieve that feat in a Test at Lord's.
Root also joins Brian Lara and Sachin Tendulkar in scoring 5,000 Test runs in two different decades, while closing the gap on Cook's all-time England tally (12,472) to just 95.
If that was not enough for him, he also took the catches for both of Sri Lanka's wickets, making him the first England player to reach 200 in Test cricket.
On a day when only 34.4 overs were possible after play began after tea, Sri Lanka’s openers Pathum Nissanka and Dimuth Karunaratne shared in an opening stand 106.
Roston Chase broke the partnership in the 31st over when he had Karunaratne caught and bowled for 42. The Sri Lankan captain who had scores of 147 and 83 in the first Test, was early into a drive and ended up scooping the ball back to Chase, who dove low to his right to snag the catch, leaving Karunaratne eight runs short of a possible seventh score of fifty or more in Test cricket.
When bad light brought about the end of play Nissanka was on 61 and Oshada Fernando on two.
Chase ended with figures of 1-33 from 7.4 overs. Jomel Warrican 0-7 from six overs and Kemar Roach 0-12 from six overs were the most economical bowlers for the West Indies.
West Indies made two changes from the team that lost the first Test with Rahkeem Cornwall and Shannon Gabriel making way for Kemar Roach and Veerasammy Permaul.
Charith Asalanka makes his Test debut for Sri Lanka, who have a 1-0 lead in the two-Test series.
Led by Captain Kraigg Brathwaite's patient 72 and propped up Kyle Mayers' crucial unbeaten 36, the West Indies scored 253 all out in reply to the home side’s first-innings score of 204.
The visitors had resumed from their overnight score of 69-1 with Brathwaite on 22 and Nkrumah Bonner on one. The pair extended their overnight partnership of seven runs to 75 when Ramesh Mendis claimed the first of his six wickets trapping Bonner lbw for 35.
The visitors went to lunch at 145-2, still 59 runs behind the hosts but they failed to build a commanding lead having lost wickets at regular intervals on the resumption after Brathwaite was bowled by Lasith Embuldeniya.
Shai Hope’s miserable Test form continued as he made only 10 while Roston Chase made 22 as the West Indies slipped from 166-3 to 197-7 as Mendis inflicted further damage on the West Indies batting order.
However, Mayers' late innings heroics proved instrumental in giving the West Indies a 49-run lead with his unbeaten knock that guided the West Indies to a small but important advantage.
Mendis’s six wickets cost 70 runs while Embuldeniya took 2-94 and Praveen Jayawickrama 2-59.
Trailing on first innings for the first time in the series, Sri Lanka got off to a bad start losing their leading run-scorer for the series, Dimuth Karunaratne, who was run out for six with only seven runs on the board. Oshado Fernando was also run out, for 14, as the home team crawled to 39-2 as close of play approached.
However, at stumps, Pathum Nissanka remained unbeaten on 21 with debutant Charith Asalanka at the other end on 4.
The West Indies trail 0-1 in the two-Test series.
