The Windies already had the series wrapped up going into Sunday's finale in Grenada, and they were again dominant in St George's.
Ireland captain Andy Balbirnie led by example with 71 while Andy McBrine gave the innings late impetus with an unbeaten 25.
However, the tourists were bowled out for 203 as leg-spinner Hayden Walsh (4-36) and Oshane Thomas (3-41) starred with the ball for the Windies.
That target proved well within the reach of the Windies in a rain-affected chase, which saw them pursue a revised target of 197 from 47 overs.
Lewis, who struck 99 in the opening game, was the talisman once more as he hit six fours and five maximums in a superb 97-ball knock, scoring his first international century in the Windies.
Nicholas Pooran added an unbeaten 43, with the Windies surpassing the target with 64 balls to spare. Attention now turns to a three-match T20I series, which begins at the same venue on Wednesday.
All-rounder Dwayne Bravo was called up for the T20s on Sunday after coming out of international retirement.
In a match shortened by rain to 43 overs per side in Sylhet, the hosts posted 322-3 in Mortaza's final game as skipper, with Das and Iqbal sharing a 292-run opening stand – the third highest in ODI history.
Zimbabwe were set a revised target of 342 and came up well short, Mortaza earning his 50th win in the format as the side's leader, the 36-year-old chipping in with 1-47 in a 123-run DLS triumph.
The home side were making fine headway when the weather closed in, the Tigers going off for more than two and a half hours with 182 runs on the board and the first pairing still going strong.
After resuming, Carl Mumba did manage to break the bond, taking three late wickets, although Tamim – who made 158 in the second match – remained unbeaten on 128.
Das smashed 16 fours and eight sixes in his stunning career-best 176, which came from 143 deliveries and ensured he eclipsed Tamim's tally from the previous outing to claim a national record in the format.
Zimbabwe's response was not nearly as spectacular, with Tinashe Kamunhukamwe falling in the first over to Mortaza and setting the tone for an innings of fruitless toil from the tourists.
Sikandar Raza did post a defiant 61, with Regis Chakabva (34) and Wesley Madhevere (42) also gaining some credit, but their contributions came in another losing effort as Mohammad Saifuddin (4-41) did most of the damage.
The result completed a miserable series for Zimbabwe, who lost the opener by a record 169 runs, before succumbing to a defeat by just four runs in the second meeting.
Pakistan already held an unassailable lead in the three-match series after the opening two fixtures, but Muzarabani ensured the tourists have something to celebrate as he starred with the ball.
Zimbabwe set Pakistan 279 for victory, Sean Williams hitting an unbeaten 118 as Brendan Taylor (56) struck a half-century and Wesley Madhevere (33 off 31) and Sikandar Raza (45 off 36) produced efficient contributions.
Mohammad Hasnain's 5-26 had helped restrict Zimbabwe but Muzarabani answered in kind, his five-for ensuring Pakistan finished their innings tied on 278-9.
The key wicket came in the penultimate over, Muzarabani removing home captain Babar Azam, who scored a run-a-ball 125, by drawing an edge with the final delivery of his 10-over allocation.
Pakistan needed 13 off the 50th over but, minus Babar, could only manage 12, with a final-ball four from Muhammad Musa forcing a Super Over in which Muzarabani proved decisive.
He took the wickets of Iftikhar Ahmed and Khushdil Shah in the space of four balls to restrict Pakistan to two runs, with Taylor and Raza securing the win with just three balls of Zimbabwe's reply.
Despite having to pick a brand new squad ahead of the series following a COVID outbreak in the camp, England crushed Pakistan by nine wickets in the first match.
Their victory was not quite as emphatic on Saturday but was never in doubt as Pakistan proved incapable of chasing down 248.
Phil Salt (60) and James Vince (56) were the stars with the bat as England were bowled out for 247 in a game reduced to 47 overs a side following a delayed start.
Hasan Ali got himself on the honours board with 5-51 for Pakistan, but England's Saqib Mahmood (2-19) was arguably the pick of the bowlers as the tourists were left playing catch-up en route to being bowled out for 195.
Dawid Malan and Zak Crawley fell for ducks in an inauspicious start for England, but Salt racked up 10 fours for his first international half-century and Vince scored his second in 18 ODIs to turn the tide in England's favour.
England then lost the next five wickets for just 42 balls, Hasan getting the prized scalp of stand-in captain Ben Stokes, but Lewis Gregory (40) and Brydon Carse (31) put on the highest eighth-wicket partnership at Lord's in ODIs with a stand of 69.
That ensured England got to a total they easily defended as Pakistan's top order failed miserably. Imam-ul-Haq followed up his duck at Cardiff by falling for one, caught behind from Gregory, before Mahmood trapped Pakistan skipper Babar Azam lbw for 19.
Mahmood then produced a beauty to dismiss Mohammad Rizwan (5) and Fakhar Zaman scored just 10 off 45 deliveries before being skittled by Craig Overton, with Saud Shakeel (56) and Hasan (31) the only batsmen to give Pakistan hope as they saw the series slip away.
Armed with an unbeatable 2-0 lead, England will aim to seal a series sweep at Edgbaston on Tuesday.
More Mahmood magic
After taking 4-42 in the opener in Cardiff, Mahmood was outstanding once more for England.
An excellent length delivery struck Babar on the pads to dismiss Pakistan's most dangerous batsman, and the ball to remove Rizwan was similarly impressive as Mahmood got one to nip away and draw a thin edge to wicketkeeper John Simpson.
Pakistan's batting blues
Having been bowled out for 141 in the series opener, Pakistan showed only limited improvement as a collective batting unit here.
The tone was set as England ripped through their top order, with skipper Babar again gone for a low score having been dismissed for a duck in Cardiff.
For a player who averages over 55 in ODI cricket, it is a bemusing loss of form.
A downpour delayed the start and limited the contest to 47 overs, which became 41 in the second innings after more rain – Sri Lanka's target of 284 trimmed to 265.
But the Proteas were never in trouble. Despite missing injured captain Temba Bavuma and the rested Quinton de Kock, stand-in skipper Keshav Maharaj was quickly rewarded for his decision to bat first.
Opener Malan stuck around for three hours and 17 minutes, during which time he enjoyed stands of 96 for the second wicket with Reeza Hendricks (51) and 86 for the fourth with Heinrich Klaasen (43).
Dushmantha Chameera belatedly got Klaasen and Malan from consecutive deliveries, but by that point there were just 12 balls remaining, with South Africa finishing on 283-6.
Given Avishka Fernando had been the match-winner for Sri Lanka in the series opener, making at least 50 in a third consecutive ODI, it quickly became clear this would not be their day when he went early for eight to a much-improved Kagiso Rabada (2-16).
Charith Asalanka starred alongside Avishka in the previous match and only he truly threatened to make a fight of the chase, scoring 77 off 69 – including three sixes – either side of the rain delay.
Chamika Karunaratne's late flurry (36 off 23, two sixes) was then ended by Maharaj, and Shamsi tidied up the tail for career-best figures of 5-49, leaving Sri Lanka well short, all out for 197.
Patient approach pays off
Sri Lanka's pace bowling attack has been effective in preventing boundaries this year, giving up just 44 per cent of their total runs conceded through fours and sixes ahead of this match – the second-lowest proportion among Test-playing nations in 2021, behind Bangladesh (42 per cent). But this did not slow Malan, who hit only 10 of the 135 balls he faced to the boundary but ran 65 singles, perhaps explaining his struggles with cramp.
Rabada back to his best
A poor showing from the Proteas' premier fast bowler in the first ODI saw him give up 66 runs, tied for the third-most in his career in this format. Yet Rabada was back on song from the outset on Saturday. He took two wickets in a stunning fifth over, conceding only a single run and prompting a further lbw review.
Rabada's contribution was overshadowed by Shamsi's efforts, but the Proteas need their main man to fire, meaning an ankle sprain in the field provides some concern.
With Australia chasing 303 for victory in Manchester on Wednesday, Maxwell arrived at the crease with the tourists reeling at 73-5 in the series decider.
But Maxwell (108 off 90 balls) and Alex Carey (106 off 114) combined for a 212-run partnership as Australia reached the target with two balls to spare.
Maxwell, who scored his second ODI century and first since 2015, said he felt free to play his aggressive game with Australia in such a poor position.
"I was probably thinking that we haven't got much to lose so I had a bit of freedom I suppose to try and take the bowling on and put a bit more pressure on them," he told reporters.
"I thought if I could make the most of that short boundary as much as I could early on and just back my bat swing. There was a fair bit of a breeze heading that way as well so I just tried to get it up in the air and I was able to get a couple pretty clean early on in the innings and then hopefully start to build a partnership with Alex.
"I knew once I started to get into the innings they would start to bowl a bit differently to me and I might be able to cash in on some loose balls, but everything pretty much went to plan.
"The way our partnership built was outstanding so it was good fun out there and I'm really happy to get that result."
Jonny Bairstow's 112 had earlier helped England to 302-7 after they elected to bat first at Old Trafford.
England captain Eoin Morgan accepted Australia were simply too good for his side.
"We were still in the game. When you break big partnerships and the ball is offering a bit, you're never out of the game," he said.
"But Australia were too good for us … we were right in the game but Carey and Maxwell played outstandingly well."
Bavuma, who replaced Quinton de Kock as skipper, could only manage one run with the bat at Centurion, but Rassie van der Dussen's unbeaten 123 helped South Africa to 273-6.
Captain Babar (103) struck 17 fours as he went at almost a run a ball, with Pakistan 186-2 when he departed.
However, they lost five further wickets for just 85 runs from there as South Africa threatened an unlikely turnaround, with some impressive death bowling from Andile Phehlukwayo fraying the nerves.
But Faheem Ashraf got Pakistan over the line off the final ball to give them a 1-0 lead in the three-match series.
South Africa were reduced to 55-4 after being put into bat by the tourists, whose early inroads owed to a blitz from Shaheen Shah Afridi (2-61), who removed openers Aiden Markram and De Kock before then catching Bavuma at third man off Mohammad Hasnain.
Van der Dussen's 116-run stand with David Miller (50) gave South Africa's innings momentum, though, with Phehlukwayo sharing a stand of 64 as the Proteas' centurion found crucial support from the lower order.
The impact of that assistance looked to be minimal when Pakistan set about their reply, Babar and opener Imam-ul-Haq (70) combining for 177 to lay the platform.
Mohammad Rizwan and Shadab Khan appeared to have steadied the ship after Anrich Nortje (4-51) accounted for Pakistan's talismen as he ripped through the middle order.
But there was to be great drama in the closing overs. Rizwan holed out to deep midwicket off Phehlukwayo and, when Shadab fell to the same bowler going for the big shot on the first delivery of the final over needing only three off six balls, comeback hopes were very much alive.
Phehlukwayo then produced three successive dot balls but Faheem took advantage of a slower ball and a wide delivery to produce the final three runs as Pakistan survived a nervier conclusion than was necessary.
That is the message from former England captain Michael Atherton, who was speaking after news circulated that Morgan is expected to announce his retirement on Tuesday.
Morgan has endured a tough spell with the bat in recent times, managing to pass 50 just once in his past eight ODI innings and failing to score in his last two outings against the Netherlands.
England have still won eight consecutive ODIs, their longest such winning streak since a sequence of the same length in 2017, but Morgan promised to step down when he was no longer contributing as a batter.
Vice-captain Jos Buttler appears poised to take the captaincy from Morgan, who has rejuvenated the white-ball fortunes of England since being appointed as skipper in 2014.
England won the Cricket World Cup in the 50-over format with a dramatic victory over New Zealand at Lord's in 2019, three years after reaching the World Twenty20 final.
Morgan's side also reached the T20 World Cup semi-finals in 2021, and Atherton believes the 35-year-old is making the right choice to step down with his legacy still intact.
"He created a one-day dynasty. Having taken over at a low point – the 2015 World Cup, which went badly – he decided it was time to change England's approach," Atherton told Sky Sports.
"For seven years, England have been as good at white-ball cricket as anybody. And that's the first time really you can say that about our one-day side.
"He will go down as one of England's most significant captains, but I think he has picked exactly the right time to go.
"He said the other day, 'I'm feeling old', and he told Middlesex he couldn't play two T20 games in succession. If you can't do that, how are you then going to captain in a World Cup when they come thick and fast?"
Morgan is set to retire as the all-time leading run-scorer for England in ODI and T20I cricket, with 6,957 and 2,458 runs respectively.
Having also played 23 ODIs for Ireland, his 225 ODIs and 115 T20s are England records for appearances, and Nasser Hussain says Matthew Mott's side will lose their greatest ever leader and a brilliant batter.
"I had an interview with Rob Key when Rob Key got the job, and I asked him about Eoin Morgan and the white-ball side," former England captain Hussain added.
"He said that one thing about Eoin Morgan is that he will always do what is best for the team. If he's not contributing to the team and if he feels him being out of the team is better for that team, then he will go. That will be the decision that Morgan is making.
"He has been short of form, short of fitness and there are other people now – there are so many white-ball batters who could be playing.
"It's not the 10 players he is taking on the field with him, it's in the one he's leaving behind because he's in that spot, and Morgan will always think of that one.
"One thing for certain is that he has been our greatest ever white-ball captain. He's a World Cup-winning captain, and he is a superb player.
"He was the one that was reverse-sweeping, reverse-scooping and playing all of these funky shots. He was way ahead of his time both as a player and as a captain."
Morgan, who started his career playing for Ireland, had captained the white-ball side for eight years.
In that time, England went to the 2016 World Twenty20 final and then overcame the pain of that narrow defeat by winning a dramatic 2019 Cricket World Cup final.
Morgan will "go down as one of the most influential figures not just in English cricket but in world cricket", according to Brendon McCullum, while Nasser Hussain lauded "our greatest ever white-ball captain" and Michael Atherton hailed his "white-ball dynasty".
But more than merely an outstanding leader - who is expected to be replaced in his role by Jos Buttler – Morgan has also been a brilliant player for England.
Indeed, there is scarcely a white-ball record Morgan does not have his fingerprints on, with his Test career lasting only 16 matches.
Despite playing 23 ODIs for Ireland between 2006 and 2009 before switching allegiances, no player has appeared in more matches for England in the format (225); the same is true of T20Is (115).
Perhaps it is no surprise then that Morgan leads England in runs in both formats – 6,957 in 50 overs and 2,458 in 20. In fact, only eight players of any nationality have scored more T20I runs.
Morgan has played with some of the sport's biggest hitters but can hold his own, too: his 220 ODI sixes (202 for England) include 17 in one match against Afghanistan at the 2019 World Cup, a record that stands to this day.
In the shortest format, he has hit 120 sixes – the most of any England star and the fourth-most overall.
A star in the field, too, Morgan has taken 46 catches in T20Is to lead England all internationals and rank joint-eighth across the board.
But Morgan will perhaps still be best remembered as the man organising the field as England scaled new heights – and he owns his fair share of records in that regard, too.
Morgan was captain for just over half of his ODI appearances (126), comfortably the most such outings of any England player, ahead of Alastair Cook (69).
It is unsurprisingly a similar story in the younger T20I format, with Morgan's 72 games as captain matching India's MS Dhoni for the record.
Morgan's sublime career is unlikely to be forgotten in a hurry, but this array of dominant records ensures that will remain the case.
Buttler has been appointed England's white-ball skipper following the retirement of long-term leader Eoin Morgan.
The superstar wicketkeeper-batsman was an obvious choice, having been a key performer under Morgan for several years.
Buttler's role in the Test set-up is less established, and the red-ball side are enjoying their own new era under the captain-coach combination of Ben Stokes and Brendon McCullum.
Big-hitting Buttler prides himself on being "positive and aggressive", as he told BBC Test Match Special on Friday. Those are qualities that would clearly work in Stokes' side, whose tactics Buttler described as "very similar" to the limited-overs approach of "taking the shackles off".
Debate around a Test return was perhaps inevitable then, but Kumar Sangakkara, Buttler's IPL coach with Rajasthan Royals, suggested he should be a candidate to bat at the top of the order, where England have had some difficulties.
Buttler was amused and bemused by the idea, saying with a smile: "I thought someone had written the wrong story, to be honest. I don't think there is much merit in that.
"Was it from Kumar? Maybe he was just plugging some Rajasthan Royals openers or something like that.
"It's been fantastic to watch the Test team over the last few weeks – I've thoroughly enjoyed tuning in as a fan; it's been incredible to watch.
"You're gripped to your seat to see what they're doing, and it's been brilliant. I've loved watching them, and I hope it continues."
Asked if he had a red ball in his bag, Buttler replied: "Not at the minute, no."
But while the white-ball skipper is happy to maintain a watching brief in Test cricket, he is keen to have the red-ball captain in his teams.
Stokes was named in England's ODI squad for the series against India, although he will not be involved in the Twenty20 international matches that follow a Test that started on Friday.
"I'm really keen for Ben to be involved in T20 cricket," Buttler said. "As with everyone, we're going to have to be careful with how we manage people's workloads.
"Ben's going to be incredibly busy. The first T20 starts after this game [the Test against India] is due to end. It's important we look after players.
"But in any format of the game, Ben is someone you want in your team."
The New Zealand all-rounder played 29 Tests, 45 ODIs and 41 T20Is over a 10-year career.
De Grandhomme averaged 38.7 in the longest format, including two centuries, as well as taking 49 wickets.
However, at 36, he has decided "this is the right time to finish" and agreed a release from his central contract with the Black Caps.
"I accept that I am not getting any younger and that the training is getting harder, particularly with the injuries," De Grandhomme said in a statement.
"I also have a growing family and am trying to understand what my future looks like post-cricket. All of this has been on my mind over the past few weeks.
"I've been fortunate enough to have had the opportunity to play for the Black Caps since debuting in 2012, and I'm proud of my international career – but I feel this is the right time to finish."
After posting 273-8 in their 50 overs, New Zealand looked to be on the point of victory when they reduced India to 153-7 in reply.
Yet Ravindra Jadeja and Navdeep Saini led a gutsy fightback that came to a head with India needing 23 runs to win from the final two overs.
By then they were nine wickets down and Jadeja holed out to Colin de Grandhomme on the long-off boundary in the last act of a gripping contest.
New Zealand's success gave them a 2-0 lead in the best-of-three series, following an opening win at Seddon Park on Wednesday, and the runs that set the platform for this latest victory were hard earned.
Opener Martin Guptill made a run-a-ball 79 before being run out in the 30th over, after he and Ross Taylor chased a chancy single.
Taylor (73 not out) and Kyle Jamieson (25no) later shared in an unbroken ninth-wicket partnership of 76 that allowed New Zealand to post a testing score, just as India threatened to bowl them out in the low 200s.
A mid-innings collapse had seen New Zealand crumble from 157-2 to 197-8, with five batsmen in succession dismissed for single-figure scores.
Spinner Yuzvendra Chahal snaffled three wickets while Jadeja (1-35) kept the run rate down, with India hoping they had reined in New Zealand sufficiently.
Shreyas Iyer was then the only batsman in India's top six who could hold his head high. He made 52, but one aggressive shot too many proved his downfall, a rash swipe at a straight ball from Hamish Bennett resulting not in the intended cut to the boundary but a clip through to wicketkeeper Latham.
Amid a string of failures with the bat, Virat Kohli had his wickets clattered by Tim Southee and KL Rahul edged a delivery from De Grandhomme into the stumps.
It fell to the lower order to dig India out of trouble, with the eighth-wicket pair of Jadeja and Saini taking the fight to the Kiwis.
The tourists required 85 runs from the last 10 overs and threatened to get them. Saini clubbed two huge sixes, but Jamieson bowled him after the second of those, ending an entertaining innings of 45 and a 76-run partnership.
A misfield led to Chahal being run out, and it effectively came down to Jadeja versus the New Zealand attack. A lusty hoick from the left-hander proved to be his last of the match, dismissed for 55 with Jimmy Neesham's full toss lashed into the grateful hands of De Grandhomme.
The series concludes in Mount Maunganui on Tuesday.
The two teams had been hopeful of ensuring the decider would produce an outcome, with the tourists 219 all out at Hagley Oval as Washington Sundar posted 51 and Daryl Mitchell took 3-25.
But with just two more overs needed for the Black Caps to reach the DLS threshold of 20 overs in response, the heavens opened to ensure yet another washout and a 1-0 series win for Kane Williamson's side.
Finn Allen's 57 had helped New Zealand to 104-1, putting them in a strong position to go on and win the match regardless.
Across six limited-overs matches, it marks the fourth instance of rain significantly impacting proceedings, with three no results and a fourth decided by DLS.
India had benefited in the Twenty20 International series, themselves winning 1-0.
With little margin for error as the Proteas battle to qualify for this year's World Cup in India, Rassie van der Dussen made a brilliant 111 and David Miller 53 as the hosts posted 298-7 at Mangaung Oval on Friday.
Jofra Archer (1-81) was expensive on his long-awaited international return in Bloemfontein, where Sam Curran (3-35) was the pick of the England bowlers.
Roy struck a sublime 113 from 91 balls, combining with Dawid Malan (59) for an opening stand of 146, but the world champions collapsed to 271 all out to go 1-0 down.
Paceman Nortje claimed 4-62, while Sisanda Magala (3-46) and Kagiso Rabada (2-46) also played a big hand as the tourists capitulated and South Africa made a great start to the three-match series with so much at stake.
Captain Temba Bavuma (36 off 28 balls) and Quinton De Kock (37 off 41) put on 61 for the first wicket before both were both sent packing by Curran.
Van der Dussen and Miller added 110 for the fifth wicket, the number three pacing his knock superbly, with Archer given the treatment in his first England match for almost two years.
It had looked like being a procession for England when South Africa-born Roy and Malan got them off to a flyer, only for the latter to strike a Magala bouncer high in the air for Bavuma to take.
Magala also removed ODI debutant Harry Brook after Nortje saw the back of Ben Duckett, but Roy raced to his hundred in only 79 balls as the boundaries flowed.
England were 196-4 in the 30th over when Rabada dismissed Roy and Jos Buttler kept them ticking along with a patient 36, but they crumbled after Nortje had the skipper caught behind in a brilliant spell.
Tabraiz Shamsi sealed a stunning win by getting Olly Stone caught and bowled in the 45th over.
Roy returns to form in spectacular fashion
Opener Roy was left out of England's T20 World Cup-winning squad last year, but he showed what he is capable with a powerful knock that included 11 fours and four sixes.
He has now passed the 4,000-run milestone for England in ODIs with 4,106 in total. Among England batters, only Joe Root (91 innings) reached that mark in quicker time than Roy's 105 innings.
Rapid Nortje burst decisive
Van der Dussen was outstanding with the bat as he ensured South Africa posted an imposing total, but it did not look like being enough as England appeared to be cruising to victory.
That was until the rapid Nortje came to the fore with a brilliant spell, taking 3-14 in four overs to turn the tide and rock England. Buttler, David Willey and Archer – out for a duck on his return – all fell to the fired-up fast bowler, who totally changed the game.
Batsman Babar is to lead his country in white-ball cricket for the 2020-21 season, the Pakistan Cricket Board confirmed on Wednesday when announcing the new list of central contracts for the upcoming campaign, which begins on July 1.
The 25-year-old averages 54.17 in his 50-over career for Pakistan and sits third in the International Cricket Council’s batsmen rankings, behind India duo Virat Kohli and Rohit Sharma.
He had already replaced Sarfraz Ahmed in charge of the Twenty20 side but will now be skipper in the ODI format too, though it is unclear when Pakistan will next be in action.
A one-day tour to the Netherlands was cancelled due to the coronavirus pandemic, meaning they may not play a 50-over fixture until they take on South Africa in October.
Ali, meanwhile, is to continue in the Test job, with Pakistan scheduled to play a three-match series against England during a tour that also includes a trio of T20 games.
"I want to congratulate Azhar Ali and Babar Azam for getting captaincy extensions," Misbah-ul-Haq, chief selector and head coach, said. "This is absolutely the right decision as they also require certainty and clarity on their future roles.
"I am sure they will now start looking to the future and start planning so that they can build sides that can perform at the expected levels."
Meanwhile, Naseem Shah and Iftikhar Ahmad were the two new additions to receive central contracts – but Hasan Ali, Mohammad Amir and Wahab Riaz were all absent from the 18-man list.
Amir and Wahab "remain in contention", however, as Misbah is hopeful the experienced duo can help aid the development of Pakistan's up-and-coming fast bowlers.
Misbah said: "The selectors have made the tough decisions to leave out Amir, Hasan and Wahab but considering Hasan missed most of the season due to an injury and Amir and Wahab decided to focus on white-ball cricket, this was the right move.
"However, Amir and Wahab are senior and experienced bowlers and they remain in contention as we believe they can still contribute to the Pakistan men’s cricket team and also mentor our young battery of fast bowlers."
Australia wrapped up the series with comfortable back-to-back victories but saw their hopes of a 3-0 sweep dashed by an improved performance from India, who were boosted by batting first after Virat Kohli won the toss.
That allowed a sublime unbeaten partnership of 150 between Hardik Pandya and Ravindra Jadeja to lay down a marker, setting the hosts a target of 303.
Aaron Finch (75) and Glenn Maxwell (59) did not lack ambition in pursuit of that total, but India - led by Shardul Thakur (3-51) and Jasprit Bumrah (2-43) - protected their lead, bowling Australia out for 289 to get up and running ahead of the Twenty20 International series starting later in the week.
It had initially looked as though this could be another comfortable outing for Australia as wickets fell around Kohli and the captain was then stopped short on 63 following a successful review.
Kohli, who became the fastest man to 12,000 ODI runs on Wednesday, was caught behind off Josh Hazlewood, claiming the scalp of India's skipper for the third time in this series and the fourth time in his one-day career - a tally only bettered by four other bowlers.
It meant Kohli will finish a calendar year without an ODI century for the first time since 2008 - his debut year - but Pandya (92 not out) and Jadeja (66 no) picked up the slack.
They combined for 12 fours and four maximums to accelerate India to 302-5 and belatedly pose Australia a serious question.
David Warner had set the tone with the bat in the second ODI but missed out with injury here, meaning Marnus Labuschagne moved up to open and made only seven before playing onto his stumps from debutant T Natarajan - India's first powerplay wicket of the series.
Steve Smith, the outstanding centurion last time out, could only muster the same total, too, after sending Thakur through to KL Rahul.
Heavy lifting from Finch kept Australia on course, but attempts to maintain this momentum were disrupted by a further two telling Jadeja contributions.
Shikhar Dhawan caught at the second attempt at long-on as Finch tried to launch the all-rounder over the fence, before Jadeja stooped for a brilliant take himself off new boy Cameron Green (21).
Maxwell's big hitting - his four sixes including one that landed on the roof and another booming reverse sweep - took the result down to the wire, but his departure to a Bumrah yorker left Australia's tailenders with too much to do.
Sri Lanka won the game by 161 runs but more importantly, the hosts now hold an unassailable 2-0 lead in their three-match ODI series.
The hosts benefitted from centuries of 127 and 119 from opener Avishka Fernando and Kusal Mendis respectively, the pair helping them to a mammoth 345-8 from their 50 overs. The West Indies did not get close, as only Shai Hope, 51, and Roston Chase, 31, offered any resistance.
The visitors would end on 184 all out against the bowling of Wanindu Hasaranga, 3-30, Lakshan Sandakan, 3-57, and Nuwan Pradeep, 2-37. There was also a wicket for Angelo Matthews, 1-20.
But Pollard did point out that things could have been different had he not dropped Mendis early in the innings and maybe, the series would now be different.
"It was the start we were looking forward to, getting two wickets early. But I put the catch of Kusal Mendis down, otherwise they would have been three down,” said Pollard.
In addition, Pollard believes his side did not have faith in the plans they made.
“We didn't stick to our plans long enough. I don't think we were up to the international standard today. Well bowled to them and well played to them,” he said.
Pollard will now look toward the final game of the series to see if the West Indies can win one.
“We weren't there in all three departments today. We can pinpoint a lot of things but I don't want to go into a lot of details. We'll do that as a team. I cop this one on the chin and we move on to Kandy."
Akeal Hosein (30-3) and Alzarri Joseph (39-3) were exceptional in reducing Australia to 45-6 before the tourists rallied to 187.
But the West Indies stumbled in their chase, slumping to 72-5 before Pooran (59* from 75) combined with Jason Holder (52) for a decisive 93-run sixth-wicket stand.
Player of the Match Pooran was crucially dropped by Moises Henriques off Adam Zampa on 26, before making his eighth ODI half-century.
Mitchell Starc, who finished with 26-3 from 10 overs, had dismissed Evin Lewis (1) and Darren Bravo (duck), before trapping Holder LBW but Pooran guided the hosts home.
Earlier, Australia struggled with the bat, with Hosein dismissing Henriques, stand-in captain Alex Carey and Ashton Turner in an excellent spell.
Matthew Wade (36) and Adam Zampa (36) rallied for Australia, before an excellent late cameo from second-gamer Wes Agar (41 from 36).
POLLARD HAILS 'SCRATCHY' POORAN
West Indies captain Kieron Pollard said allowing Australia to reach 187 was disappointing but hailed Pooran's determination after a "scratchy" knock.
"What was good this time around was the fight by the guys, Nicholas Pooran getting that half-century and Jason Holder as well," Pollard said.
"Pooran has been looking like his old self again. He was a bit scratchy tonight but sometimes that's what you need in a game like this. You want someone to scrap and I think they both scrapped well for us to come through for a victory."
The West Indies avoided suffering back-to-back home defeats for the first time since August 2019.
Pooran's innings also took him past 1,000 ODI runs, becoming the 39th West Indian player to achieve the feat and the joint-third fastest for the side (Viv Richards – 21, Gordon Greenidge – 23, Ramnaresh Sarwan – 27).
AUSSIES STILL BULLISH AHEAD OF DECIDER
Australia are unbeaten in their past six ODI bilateral series (W4, D2) against West Indies and missed out on the opportunity to seal another victory but Carey remained bullish ahead of Monday's decider.
"Bring on game three," Carey said. "The batting group has a bit to prove to get a good score on the board for our quicks but our quicks and spinners are doing a great job."
The stand-in skipper bemoaned Australia's top-order batting, with none of the top six scoring more than 16.
"Obviously it doesn't help when you're five for not-a-lot," he said. "Wade and the bowlers did a great job to get us to a total and we were back in the game.
"We took some early wickets again and the belief was there. We created opportunities and we were in the game in the back end. Unfortunately we couldn't quite close it out and it proved we were 20 or 30 short."
Number three batsman Malan picked up the pace following a considered start to eventually finish on 114 not out and drag England to victory in the first ODI.
Having limited Bangladesh to 209, England's response for a while looked in danger of falling short.
But Malan fittingly clinched the win after scoring his fourth ODI century, making him the second-fastest man to that mark in his 16th match.
The 35-year-old, who has spent time playing in the Bangladesh Premier League, also had a hundred in his previous ODI innings against South Africa last month.
"I've spent a fair bit of time in Bangladesh, especially at this ground, which helps," Malan said.
"I told Jos [Buttler] it would have been tough to chase if they'd have got 30 to 40 more runs. It's satisfying to get over the line, handling pressure is part of the job."
Malan was required to do the heavy lifting alongside a succession of low-scoring partners as England were reduced to 65-4 at one stage.
Victory was achieved with eight balls to spare, however, leaving captain Jos Buttler delighted.
"These are tough conditions," he added. "Mala's innings was outstanding and is an example for us on how to play on these wickets.
"There was plenty in the wicket for both spinners and pacers. There's plenty of areas to work and improve on. It's about small partnerships on wickets like these. [They] can be really valuable."
The Proteas were due to travel to Sri Lanka in June for three ODIs and a trio of Twenty20 fixtures against their hosts, only to cancel due to the coronavirus pandemic.
For the same reason they called off a planned trip to the Caribbean set for July and August, when they were due to play two Tests and five T20 matches.
While there was hope of facing West Indies in September instead, director of cricket Smith admits such a scenario is impossible for Cricket South Africa (CSA) due to the rearranged Indian Premier League season.
Several of the country's leading names are contracted to franchises for the T20 tournament, which seems set to be staged in the United Arab Emirates this year.
"The West Indies tour has been postponed indefinitely," Smith told the media on Saturday.
"We are struggling to find the time with the Indian Premier League, when our players are likely to be needed from the beginning of September. Sri Lanka also [postponed].
"I expect that once things get up and running, our team, on the men's side, I would say from November onwards, if all goes well, it will be a really busy period for South African cricket, probably playing in times that we haven't played before and trying to cram in a lot of the missed tours."
As for his own situation with CSA, Smith reaffirmed his commitment to the role amid recent questions raised over his appointment, as well as the coaching staff he put in place.
Mark Boucher was named as head coach ahead of the home series with England, while fellow former international team-mates Jacques Kallis and Paul Harris were introduced to work as batting and spin-bowling consultants respectively.
"If you look at some of the things which are being said around appointments, my appointment and the appointment of my staff, I think some of those things are extremely unfair," Smith said.
"It was good to see CSA president (Chris Nenzani) put that straight with his most recent comments. But I have to come back to my value system and why I got involved in this job.
"Cricket South Africa courted me for a while, I went through the same interview process as everybody else in getting the job.
"I got involved because I have got cricket at heart and to be part of the solution. I want to help create a strong Cricket South Africa."
