Need 119 runs to win
Tidy from Andy McBrine, in the scheme of things.
Well, it is up until the middle of the over, when Jonny Bairstow absolutely muscles a drive straight back past him for four. That was hit so, so hard.
Every time, James Vince draws us in...
...and then lets us down.

England bowler on BBC Test Match Special
Really nice shot from Banton, classical on-drive.
Target 213
Jonny Bairstow smashes the ball down the ground, almost taking out poor Tom Banton's ankles in the process, but it's just a single.
Banton then gets in on the act with a gorgeous drive down the ground.
Ah. Campher bowls a no ball, and Bairstow has a free hit...
Ooft, Curtis Campher almost has another!
A loose drive from Tom Banton, losing his shape slightly, and a thick inside edge beats stumps and keeper to go racing away for four.

England bowler on BBC Test Match Special
Ireland look like they have got a real player in Campher, both with bat and ball, a player they can build a real future around.
Bairstow 57, Banton 1
Shot!
Short from Andy McBrine, loose, asking to be hit, and Jonny Bairstow absolutely smashes it through mid-wicket for four. That made the most glorious noise off the bat.
Ouch.
Target 213
Tom Banton sees off his first two balls, and that'll be a wicket maiden from Curtis Campher.
What a couple of days Curtis Campher is having.
It'll be Tom Banton to have a whack at four.
Tymal Mills
England bowler on BBC Test Match Special
Really good delivery he can't seem to do anything wrong at the moment. It seamed back in through the gate, he has taken to international cricket like a duck to water.
Vince b Campher 16 (Eng 71-2)
Well, the good news for James Vince is he hasn't been caught behind.
The bad news is, he's been clean bowled, middle stump out the ground.
Something very undignifed about having to climb into the stands to field a six.
Curtis Campher, who starred with the bat earlier, is now coming on for a bowl.

It was poor Harry Tector who had to clamber over the empty seats to retrieve the ball after that Bairstow six.
If you know how to stop Jonny Bairstow, please write to Mr A Balbirnie, c/o the Ageas Bowl, Hampshire...

This has been the one-day cricket we have been used to from England. Jonny Bairstow an excellent innings so far.
Jonny Bairstow has equalled the record for the fastest half-century by an England batsman in an ODI. He now shares top spot with Eoin Morgan, who smashed 50 against Australia in that astonishing match in 2018.
21 balls. That's proper thwacking, isn't it?
Eng 69-1
My word!
Straight down the ground for six and Jonny Bairstow brings up a 21-ball half-century, his quickest in an England shirt. Eight fours and two sixes. Wallop.

If Bairstow does want to get this done quickly then he needs to place these big shots carefully. With no crowd to throw the ball back, if he hits too big a six it could waste precious time.
