Roy lbw b Young (Eng 34-2)
Successive fours for Roy but Young gets his revenge as he traps him in front and the batsmen decide against a review. Both openers back in the hutch.

There are not many positives to bio-secure, crowd-less cricket but being able to hear the sound of Jason Roy's bat on ball is one. Crack.
Target 173
The first maximum of the innings as Roy finds his touch, hoisting McBrine way over mid-wicket with a slog sweep.

That's trademark James Vince. Stands tall, has beautiful hands and he's a sweet timer of the ball. It's just about trying to put that innings together in an England shirt.
Target 173
We've already had one nonsensical run-out in the match and there is another mix-up here as Vince is sent back but the throw misses the stumps. Back at the striker's end, Vince gets away with a stylish push through the covers for a single.

Well done umpire Carberry! My first instinct was that it was just outside. Slightly lazy from Jonny Bairstow, he had a bit of an issue in the World Cup when teams started with spin against him. Full credit to the Irish bowlers, well bowled.
Target 173
James Vince is the new man, on his home ground. Plenty of shots in his repertoire, made 66 at the weekend with 12 fours, what can he do tonight?
Bairstow lbw b McBrine 2 (Eng 12-1)
They were right to do so, it was ticking all the boxes with a little bit of turn and Bairstow marches off back to the pavilion.
Good start for McBrine and he has trapped Bairstow on the pad going forward, Ireland ask for a review.
With McCarthy off the field it will be more spin but it is Andy McBrine who is entrusted with the ball, he bowled six overs 0-37 at the weekend. There is a slip in there for him and a short mid-wicket.

Ireland raised a flag in the warm-up games that it was difficult to pick out a white ball in front of white and beige seats in an empty ground - what was it like when you played here?
It was difficult if the ball got dirty, when it got bashed around in the death overs. I used to field square of the wicket so it was difficult to pick it out, But also the sun gets quite low here and the ball can get pulled quite flat at you.
Target 173
The first boundary of the England innings as Roy flicks one off his pads off Craig Young that evades the fielder at backward square. The Ireland innings contained 13 fours and a six, a reminder they were 28-5 in the seventh over.

McCarthy doesn't look happy. He might have felt something go on delivery. Desperately unlucky.
Target 173
The stocky figure of Paul Stirling completes the over by bowling the final ball with his three-step off-spin.
Roy was out first ball in the Lions match at the weekend but he gets away by slicing one in typically aggressive fashion through the gully for two. What's happened there has the TV umpire missed a no-ball? It has caused an injury to McCarthy in any case and he is leaving the field.
Thanks Callum, so how are England going to play this then? Roy and Bairstow not known for being watchful. Still delightful unbroken evening sunshine but as Matt said, floodlights on wasting electricity, all part of the regulations no doubt. Here we go, Barry McCarthy to open the bowling.
That's me done for the time being. I'll hand you back to Jamie Lillywhite to take you through the start of the England innings.
The Ireland players, looking to defend 172, are making their way out to middle.
Cricket Ireland chief executive Warren Deutrom on TMS: "Our Ireland Wolves team beat the full first teams of Bangladesh and Zimbabwe last year, so we're very confident about the young players coming through. I think you're witnessing a team in transition."
This is England's first home ODI since they won the 50-over World Cup last summer and Paul Collingwood has also been talking about how they keep the momentum going from that win.
"The simple thing is that in the past we have had these moments of World Cup wins like in 2010 and when we do well we have actually seemed to have a mass exodus of players or a new coach in or something like that," Collingwood said.
"So the challenge now is to continue with that same approach and not just continue from the very top but filter it down to county cricket and really get the competition for places and the skill level and that really aggressive approach we have in our cricket filter down the system. As a team you always have to move forward."
