A century from Shai Hope in his first game as West Indies captain helped the tourists to a 48-run win over South Africa at Mercedes-Benz Park.
Hope hit 128 not out from 115 balls to lead West Indies to an imposing total of 335-8, their highest score against South Africa in ODIs.
His opposite number, Temba Bavuma, did even better as he managed 144 from 118 in reply, but a lack of help from elsewhere saw the Proteas fall short of the target.
Openers Brandon King and Kyle Mayers put on 67 for West Indies' first wicket before the latter hit Bjorn Fortuin (2-57) to deep midwicket to the waiting hands of Ryan Rickelton for 36.
Hope and Nicholas Pooran steadied the innings after the further losses of Shamarh Brooks (0) and King (30) with a partnership of 86 before Pooran was dismissed by Gerald Coetzee for 39, but Hope established another solid stand with Rovman Powell (46) through the middle overs.
After Jason Holder went for 15, it looked like Hope may run out of partners as Akeal Hosein (2) and Odean Smith (1) departed quickly, but Alzarri Joseph (13 not out) played a solid supporting role in the final overs as Hope clattered some more crucial runs at the end of the innings.
The Proteas' chase got off to a good start as Quinton de Kock and Bavuma provided 76 for the opening wicket before De Kock was trapped lbw by Mayers for an aggressive 48 from 26 balls.
Bavuma kept things ticking over along with Rickelton (14) and Tony de Zorzi (27), while Rassie van der Dussen (8) and Tristan Stubbs (6) exited quickly as South Africa's captain was also running out of partners.
Marco Jansen (17), Fortuin (1) and Coetzee (1) were not far behind, before Bavuma's innings was finally over when he gloved one from Joseph (3-53) down the leg side and into Hope's waiting hands, with the same duo combining to dismiss Tabraiz Shamsi for a duck to secure victory.
It's the Hope that kills you
Hope seems to thrive in the 50-over game more than any other format, averaging 50.4 with the bat in ODIs – the best of any player for West Indies in the history of the format (min. six innings) – compared to 25.0 in Tests and just 17.9 in T20Is.
The new West Indies captain's unbeaten 128 here was his 14th ODI century, which he reached by clubbing five fours and seven sixes.
Bavuma's brave riposte not enough
It will be little consolation to Bavuma that he outscored Hope, but it was still an innings worthy of acclaim from the 32-year-old.
His 11 fours and seven sixes briefly gave the Proteas a chance, but a lack of support meant he was on a hiding to nothing.
ECB chief insists no decision made on Mott future
England and Wales Cricket Board chief executive Richard Gould has denied reports a decision has already been made on Matthew Mott's future as white-ball coach.
Mott's future has been called into question in the aftermath of England's failure to defend their T20 World Cup crown in the United States and West Indies, losing to India in the semi-finals.
Mott also oversaw England's calamitous 50-over World Cup campaign last year, as they lost six of their nine matches in India and crashed out in the group stage.
Reports earlier this week suggested the decision had already been made to dispense with Mott's services, with Eoin Morgan a contender to succeed him, though the former limited-overs captain has since said he has no interest in the role.
Asked by BBC Test Match Special if Mott's future had already been decided, Gould said: "That's not true. That's certainly not true.
"Matthew Mott is a really good guy and coach. He's got a great track record and it is the same with [captain] Jos [Buttler].
"We are always assessing options - that is what happens in high-performance sport, you are always assessing your options.
"You never want to be drawn into being given the dreaded vote of confidence or anything like that. Competitive sport always brings scrutiny and decisions.
"We'll constantly want to assess our options but we'll always want to do the right thing by the sport, the team and individuals."
West Indies grab three late wickets on day one as third Test against England in the balance
England lost three wickets in a dramatic end to day one of the third Test against West Indies, leaving them in a precarious position after restricting the tourists for 282.
Gus Atkinson finished with figures of 4-67, while Chris Woakes took 3-69 for England, as only a fine sixth-wicket stand from Jason Holder and Joshua Da Silva saved West Indies from being bowled out for a much lower total.
But England, chasing a 3-0 series whitewash, let their dominant position slip when taking up the bat for the final 35 minutes, Zak Crawley (18), Ben Duckett (3) and Mark Wood (0) being dispatched as bowler Jayden Seales dropped them to 38-3.
Windies skipper Kraigg Brathwaite won the toss and chose to bat, leading his side to a solid start before a spell of three wickets in five overs before lunch put England on top.
Atkinson accounted for Mikyle Louis (26) and Alick Athanaze (2) on either side of Wood sending stumps flying with a full delivery to dismiss Kirk McKenize for 12.
Brathwaite's knock of 61 was brought to a halt shortly after the action resumed, the captain gloving Wood's leg-side ball to Jamie Smith as the tourists slid from 76-0 to 115-5 in 45 balls.
Holder (59) and Da Silva (49) then shared 108 to drag the Windies towards a respectable total, but things looked bleak for them when the latter feathered Woakes' ball through to Smith.
Having gone 30 overs without a wicket, England needed just 14 more to polish off the tail, the highlight being a terrific diving catch from Joe Root to send Gudakesh Motie (8) packing.
England were given just over half an hour with the bat to cap Friday's action, but any hopes of a serene finish were soon dashed.
Holder made two terrific catches off Seales' bowling, the first from Crawley's thick outside edge and the second to dismiss Wood for a duck, either side of Alzarri Joseph's cracking delivery accounting for Duckett.
That spell ensured what had been a good day for the hosts ended on a sour note, with the Windies sure to target quick wickets when the action resumes on Saturday.
Data Debrief: Atkinson and Seales dominate
This series began with all the focus on James Anderson as England's greatest-ever bowler bowed out at Lord's, but Atkinson has taken centre-stage since making his Test debut in the opening match and now has 20 wickets through five innings.
That is eight more than West Indies' Jayden Seales, the next-most prolific bowler in this series, has managed.
Seales was determined to have an impact on day one, though, and his two wickets at the death have set the stage for a far more competitive match than those England won at Lord's and Trent Bridge.
Bairstow set sights on swift England Test return
Jonny Bairstow bit back when asked if he was targeting an England return, insisting it is "all I want to do."
Bairstow was dropped from England's Test team for the ongoing series against West Indies.
The 34-year-old was part of England's T20 World Cup squad, and played in all five Tests of the tour of India earlier this year.
Bairstow has made 100 Test appearances, and when asked what his immediate target was, the wicketkeeper-batsman told former England captain and now-BBC Sport pundit Michael Vaughan: "All I want to do is play for England. That's end of.
"You don't need to ask me that do you? I think you know me well enough and I think you've known me for long enough to know that."
Bairstow did, however, enjoy a break away from the game, having had four weeks off before he joined the Welsh Fire for the Hundred.
He said: "At the same time it's been a great period of time.
"I had the best part of seven months away from home. Since January, I had five nights at home in my own bed since, until three weeks ago.
"That's the thing you have to sacrifice, time at home but at the same time, when you are away for that period of time, it takes its toll."
England are 2-0 up against the Windies in their three-match series, with the final Test starting at Edgbaston on Friday.
