TV cameras show a chilly Peter Willey in the crowd, watching son David make his international debut. They are the fifth father-son combo to have played ODIs for England. The whippy Mark Wood stands still on his mark, pumps in, then almost hurls himself off his feet when he delivers the ball. Hint of swing both ways, pace in the mid-80s, reasonably accurate. Only a wide from it.

James Taylor rubs his mitts with a hand-warmer as he directs Tim Bresnan to share new-ball duties. Bresnan, playing in his first international since England were beaten by the Netherlands at last year's World T20, is immediately on the money, on Porterfield's off stump. The Yorkshire man supposedly has a new action, but the only new addition seems to be a big support on his troublesome right elbow. No great pace, but accurate. The only run is a Porterfield flash through vacant gully.

"I do think Eoin Morgan should have been here. He is the one-day captain and it is probably in his interests to be here leading the team. It is disappointing in that respect but a great opportunity for James Taylor and some other young England players."

Wood, tall, haircut you can set your watch to, has a shortish, straight approach. A touch of swing sends the ball down Porterfield's leg side for a wide, with the skipper then taking a single in the covers to get off the mark. As spectators shuffle into their seats, Wood gets bounce to rattle Stirling's splice, but then strays to be taken for a couple to long leg. Last ball, in-hoop, appeal. Going down the leg side. Mixed start, but some encouraging wobble.

"The Irish guys are a very close unit, a core group of guys who get on very well and I think Phil really emphasised that through his coaching style. Ireland also have some exceptional players. They no longer have bits and pieces players. They showed that at the World Cup."

Mark Wood is at the end of his run-up, it will be good to see him with the ball, rather than the drinks tray, in his hand. The Durham seamer, on debut, will be bowling to Porterfield, with Paul Stirling at t'other end. Two slips.

"England will be licking their lips. I think it will be old style one-day cricket today. Batsmen will have to dig in and it will get easier."

It's chilly. The England fielders are rugged up under big sweaters. They take the field led by their mascot, I mean captain James Taylor. Grey, cold, damp. Feels like a bowling morning.

Nigel: At last! A change from the usual faces well done England!

We'll talk plenty about England and their five new faces as the day progresses, but there's a couple of things worth noting for Ireland. Firstly, captain Will Porterfield will open the batting in what is his 200th one-day international. Also new coach John Bracewell will be watching on before taking he takes charge. At the moment the players are meeting dignitaries - lots of smiles and handshakes.

BBC Weather's Darren Bett: "There may not be an awful lot of play today. The forecast is not good. We could get an hour or two of play but once the rain arrives it is not moving quickly and may not clear away until about nine or ten o'clock tonight."

The covers are off, we'll start on time. However, the finish might be in doubt. It's already grey and there's not many of what was expected to be a 10,000 crowd in their seats. The forecast doesn't look too clever either...

Will from Enniskillen: Wonder how the 5 new England players feel about taking on the best European team from the World Cup?

"I think it was an important toss to win and Ireland will have to bat well, particularly in the morning session and get stuck in."

BBC Radio Test Match Special

And, while you're texting, tweeting and emailing, you may want an audio accompaniment for your Friday afternoon in the office/at school.

Test Match Special is on the air from Dublin and can be heard on Radio 5 live Sports Extra, here online and via the various BBC apps.

Rob: Good opportunity for an associate nation. Why don't we play them in 3 day warm up games before test series too?

Got all that? Excellent. Then it is left for me to ask you what you make of it all. Text 81111, tweet using the hashtag #bbccricket, external or email tms@bbc.co.uk. Also, on the morning after a general election, have a little think about this. If you were put in charge of English or Irish cricket for the next five years, what would your manifesto be?

Ireland: William Porterfield (capt), Paul Stirling, Ed Joyce, Niall O'Brien, Andy Balbirnie, Gary Wilson (wk), Kevin O'Brien, John Mooney, George Dockrell, Alex Cusack, Craig Young.

England: Alex Hales, Jason Roy, James Vince, James Taylor (capt), Zafar Ansari, Jonny Bairstow (wk), David Willey, Adil Rashid, Tim Bresnan, Steven Finn, Mark Wood.

The Ireland XI is very familiar, featuring 10 players who played at the World Cup. Medium-pacer Craig Young comes in, he was part of the 15 in Australia and New Zealand, but didn't get a game.

Northants all-rounder David Willey, Hampshire batsman James Vince, Durham seamer Mark Wood and Surrey pair Zafar Ansari and Jason Roy all make their England one-day debuts. There are also recalls for Tim Bresnan, Adil Rashid and Jonny Bairstow.
