Target 335
Brilliant start for Potts, beating the bat of Balbirnie with his first ball.
Matthew Potts is getting ready and is set to open the bowling here for England. Andrew Balbirnie will face the first ball.
None of England's World Cup squad are in action during this Ireland series, but there is still a lot to play for in case any late call-ups are required during the tournament.
So why not put yourselves in the shoes of England's selectors and have your say.

Thanks, Ffion.
Ireland are attempting to pull off their most successful chase in ODI history, but considering how England started their innings, they would've certainly taken 335 as a target after a few overs.
Looking forward to seeing the likes of George Scrimshaw and Tom Hartley have a bowl on debut, while this game also presents big opportunities for Matthew Potts, Brydon Carse and Rehan Ahmed.
Right then, England are ready to start their defence of 334, with Zak Crawley taking the team through some last words of wisdom.
Ireland openers Paul Stirling and Andrew Balbirnie are also poised, which is my cue to hand over to Jonty Colman to take you through the start of the second innings.
In case you missed it earlier, England handed out four debut caps this morning.
Hain was joined by Surrey sensation Jamie Smith, who only managed nine in his first international outing.
We'll also be seeing the spin of Tom Hartley and George Scrimshaw's pace in action shortly.

Luke Davies: Listening to the match and it's mad that these are the players who couldn't get into the World Cup squad. I mean, this is a mix of England's Second and Third XIs. The strength in depth is just ludicrous!
It wasn't a great day for Ireland's bowlers overall but George Dockrell was the standout, with 3-43 while Craig Young was also impressive with 2-38.
They helped Ireland wrestle back some control in the middle overs, chipping away with regular wickets.
There were important contributions from Ben Duckett and Brydon Carse too, but it was debutant Sam Hain who followed in Jacks' footsteps with an impressive 89 from 82 balls.
It allowed England to reach a competitive 334-8 despite a decent fightback from Ireland's bowlers.
The Trent Bridge crowd was then treated to the Will Jacks show.
The opener hit four sixes and seven fours in his 88-ball knock, eventually falling for 94 by trying to hit another into the stands.
A strange innings, really.
England started emphatically, racing to 55-0 from the opening six overs as Ireland's bowlers couldn't string together any consistency.
Craig Young eventually got the breakthrough, dismissing Phil Salt for 28.
Barry McCarthy oversteps from what everyone thought was the final ball, and gifts England a free hit.
It doesn't spoil a good closing over, though, as Matthew Potts can only manage a single.
The visitors fight back well after England's blistering start, but a difficult run chase awaits.
Ireland need 335 to win.
Hain c McBrine b McCarthy 89 (Eng 328-8)
Sam Hain falls short of his century, but what a knock on debut.
He gets a leading edge off a Barry McCarthy slower ball, and Andy McBrine takes a simple catch at mid-off.
The England team applaud a fine innings from the balcony as Hain departs.
Here's how England lost their seventh wicket, with the full toss leading to Rehan Ahmed's departure.
Make that four more.
Hain easily deals with a Mark Adair full toss, and he's got a century in his sights now if he can keep most of the strike in this last over.
There we go.
Sam Hain clubs one down the ground from the first ball of Mark Adair's 10th over.
Sam Hain may not have found the ropes as regularly as he'd have liked at the closing stages of this innings, but Tom Hartley does it pretty well.
He crunches Josh Little through the covers for four for his first boundary.
Little finishes with 1-82 from his 10 overs.

If you are Jos Buttler, Sam Curran or Liam Livingstone, in this situation, you are probably thinking to try and hit every ball for four or six and we've not see that yet from Sam Hain.
Josh Little is going to bowl his last over.
It's not quite gone to plan for him today. Can he finish on a high?
Tom Hartley is a left-arm spinner whose strengths are containment and accuracy.
The son of former international 400m runner Bill Hartley, he climbed through the ranks at Lancashire's age group teams while cutting his teeth in the Liverpool Competition.
