And with that, it's time to bid you farewell. We promised you the possibility of an upset at the start, and Ireland delivered magnificently. They have continued their proud record of World Cup giant-killings and more importantly, put themselves in a great position to qualify for the quarter-finals.

If that's whetted your appetite for Cricket World Cup upsets, join us again at 21:30 GMT tonight to see if Scotland can pull off a even bigger shock against co-hosts New Zealand. See you then!

"Ireland gave a superb bowling performance up until the last 15 overs. The West Indies seemed to have put a total on the board that would be enough but Ireland weren't phased, they walked out there as if they knew they were going to knock those runs off."

"Ed Joyce looked on a different planet, he was a joy to watch, I would love to have seen him bat to the end he was that good. Ireland should be very happy with the way they bowled and batted. They've got work to do with their bowling at the death but all teams have.

"I'd say this is a better victory than the one against England, that was a one-man show from Kevin O'Brien, this was a team effort, five or six people putting their hands up and delivering a world class performance.

"They can certainly look to get out of the group. Every other so called big team in the group will have watched this and be very nervous."

Nick Bruzon:, external Wow. That's a story to wake up to. Congratulations, Ireland ! Looks like Eoin Morgan has backed the wrong horse.

"From an outsider's point of view there is being cool and being a fractured team and the West Indies really do look a fractured team at the minute."

Ireland were brilliant, but where do West Indies go from here? They looked all at sea, their top-order talisman Chris Gayle appeared well short of his brilliant best, and their bowling, under the unconvincing captaincy of youngster Jason Holder, was remarkably toothless.

Their lacklustre body language hinted at deeper issues too, and they now face an uphill battle to qualify for the knockout stages - they will probably have to beat one of India, Pakistan or South Africa. On this evidence, that would be a considerable surprise.

Man of the match Paul Stirling: "It's great to get that first win, and hopefully we'll get two out of two in a week's time. I owed the lads about 90 runs after dropping Sammy, so it was nice to get a few. It was a good toss to win and insert West Indies, and luckily we were able to chase it down."

Ireland captain Niall O'Brien: "Sammy and Simmons played well but we thought 300 was around a par score. There's no reason why we can't qualify for the knockout stages."

Ireland's win in 45.5 overs is the sixth quickest of all successful ODI run-chases of 300 or more.

"I think West Indies thought they would get a lot more loose stuff early on. To be fair they didn't throw it away but by the time the middle order was skittled by Dockrell that was more down to good bowling than bad batting."

Well, what a remarkable victory. If you're awake at this early in Ireland, you've been richly rewarded with a superb performance by your team.

Ireland bowled very well for the first 25 overs of the match, with George Dockrell and Andy McBrine befuddling West Indies with canny spin. Darren Sammy and Lendl Simmons then threatened to take the game away from Ireland with an explosive partnership, and 305 looked a formidable total.

But Ireland were in control of the chase from ball one, with Paul Stirling and Ed Joyce batting with authority and plenty of panache, and they got home with plenty to spare.

"Before the game I'm happy to admit I thought Ireland would come up short. I thought West Indies couldn't possibly play as badly as they had in the warm-up games and they'd just be too strong, but from ball one Ireland were the better team.

"Ireland thoroughly deserved the victory."

They've done it! Just as he did in Bangalore four years ago, John Mooney hits the winning runs to set the seal on another famous victory for Ireland.

For the third World Cup in a row, Ireland have humbled one of the established nations. They chased down a huge total with total confidence and composure, and it feels like this victory could be the most significant of the lot.

They've given themselves a fighting chance of qualifying for the quarter-finals, and with the ICC set to reduce the number of teams at the next World Cup, they've sent a message that they belong at this level.

Two more singles take Ireland within one shot of glory. John Mooney hit the winning runs against England in 2011 - he has the chance to do it again here...

Niall O'Brien wallops consecutive fours to put smiles back on the faces in the Irish dugout. Panic over!

This is painful viewing. The O'Brien brothers' partnership lasts all of two balls as Niall calls Kevin through for a tight second run and Dwayne Smith's accurate throw finds the burly batsman well short of sanctuary. Ireland are making a right Devon Loch of this...

Kevin O'Brien, the hero of that incredible win over England at the last World Cup, is the new man.

They couldn't, could they? Ireland's rampaging juggernaut of a chase has slowed to a crawl, and the pressure tells as Wilson cracks one into the mitts of Chris Gayle at cover. Suddenly, 15 runs looks a rather long way away...

This would be only the fifth time that a team has chased 300 or more to win a World Cup match - and the third time by Ireland. No bowling attack will underestimate this line-up now. Wilson and O'Brien pick up three singles from Kemar Roach's over.

Gary Wilson is the new man for Ireland. Taylor keeps Ireland honest, just a single from that over. Ireland have only mustered three runs from the last two overs - they just need to keep their heads here.
