Now then, some finish-line jitters from Ireland? Andrew Balbirnie seizes on a short ball from Taylor, but he hasn't quite got all of it and it's comfortably pouched by Darren Bravo at deep mid-wicket. Not a hint of celebration from the West Indies - they evidently feel this match is done.

Ireland must have felt this game was slipping away from them when Darren Sammy and Lendl Simmons were carting their bowlers to all parts, but they've pursued this chase with utter conviction. Can I be mischievous and ask you to imagine how England might have fared chasing down 305? Anyway, Andre Russell is handed the ball, and delays the inevitable with a tight over which yields just two singles.

Hugh in France:, external Why did the West Indies bother going? They don't look at all interested.

Andrew Balbirnie, with just 12 ODIs under his belt, is the new man. He'll be nervous, no matter the apparent simplicity of the situation. Taylor fritters away one of the 31 runs the Windies have to play with with an utterly brainless wide. And there go four more - Taylor overpitches and Balbirnie times him through the covers like a old pro. And it's no fluke - an attempted slow ball from Taylor gets the same treatment. Van Morrison playing on the tannoy, emerald-shirted fans in raptures - this is Ireland's day.

"There were just a few high fives after that wicket. The West Indies couldn't look less interested in this game."

No hundred for Ed Joyce - he picks out Darren Bravo on the fence at deep cover. Is there life in this game yet? The West Indies need the defibrillator, and fast.

Last time Ireland shocked the world, it was Kevin O'Brien who hogged the headlines, this time big brother Niall is muscling in on the glory. Holder puts one in the slot and O'Brien opens his shoulders and slams him to the long-off boundary - that brings up his fifty. And he goes again - shuffle to leg, plenty of bottom hand, ball flying to the rope. 36 needed from 66. West Indies are bruised, bowed, surely beaten.

That might be West Indies' last chance. It falls to the young skipper Jason Holder - Niall O'Brien tries to hoick a good slower ball from Taylor and mistimes it, it goes miles in the air, Holder does all the hard work running round and then watches in agony as the ball clanks off his wrists and hits the turf. Disaster.

Will O'Brien make him pay? You bet. First he belts Taylor over mid-off for four, then he spanks him through extra-cover for another. Taylor is going at 11 an over! 50 needed from 72, Ireland on the brink of another brilliant World Cup giant-killing.

67 needed for Ireland. Cap'n Holder is back - he's down to his last chips in this casino. Ireland hold all the aces, especially with the fielders in the circle now, and that allows O'Brien to back away to leg and loft a peachy inside-out drive over the covers for four. Ireland are doing this in style.

Time for the batting powerplay, often a harbinger of doom for England - will it put the hex on Ireland? Jerome Taylor is handed the nut, and he momentarily staunches the flow of boundaries, but Ireland continue to run the singles hard - five from that over. The West Indies need a flash of inspiration from somewhere...

Chris Gayle, a man with enough X Factor to lock down the Christmas number one spot for decades, is back into the attack. But Ed Joyce looks serene out in the middle and he finds the rope again with a handsome chip over extra-cover. Ireland in control, West Indies drifting like an abandoned pedalo...

"The West Indies have to go to their x factor bowler. I'm just looking at their line-up to see who that might be."

Jason Holder is ringing the changes - the bustling Andre Russell is the latest bowler to be tried. He can't turn the tide though - he obligingly serves one up on Niall O'Brien's hips and the batsman flicks him to the square-leg boundary. Russell then strays with a wide, and how costly the extra ball proves - short again and O'Brien cracks him to the boundary at point! Surely it's Ireland's to lose from here...

Allistair Elliott:, external The Windies have run out of ideas.

Lendl Simmons, who incidentally is the nephew of Ireland coach Phil, is called on to deliver some medium-pacers. That will please Uncle Phil, much too short and O'Brien clobbers it past the sprawling Samuels at long on. And another boundary as Joyce pulls powerfully through backward square! Ireland's runs needed are down to single figures, and the upset is very much on!

Mark Kelly:, external Not much talk on the field between the West Indies players. A sign they are very worried. Need two wickets before Powerplay.

Samuels hasn't quite got his length locked down yet and another half-tracker is punished by O'Brien, swivelling on it in a flash and pulling hard to the cow-corner boundary. That's not so clever from O'Brien, who flirts with one outside off and nearly gets a tickle through to the keeper. "No, Niall!" he admonishes himself.
