"The Root show continues. It is fantastic for such a young player to perform like this consistently. All credit to him."

That was not so much an over as a public flogging. Twenty-three runs in total.
Two fours apiece for Joe Root and Sam Billings, before Billings crowns the corporal punishment with an enormous slog six over long-on.
Nathan McCullum won't be coming back for any more of that. England pressing the pedal.
Joe Root raises his bat as he brings up his fifty with a four off the opening ball of the over off Nathan McCullum.
Tim Southon:, external Rarely have I seen a cricketer so far in the zone as Root. Top batting on any surface, in any form of the game.
Graham Chandler:, external Wickets tumbling but good to see England trying to reach the magic 200.
Tricksy stuff from Sam Billings, so tricksy he confused himself.
As he sets off for his run, admiring clever little scooped glance down to fine leg, ghe loses his footing. And his bat. And ends up crabbing home at the other end only just better than all fours.
The boundaries have dried up a bit for England though. Six singles off that over
Richard Harmon:, external Just how good is Joe Root?! Must be the most naturally gifted player we've had come in to the team since you know who..
Who might that be Richard? Initials KP perhaps?
Sam Billings is the new man in for England, but the injection of nitro-boost is yet to come for England.
Six runs off the over.

"Often, these T20s can feel low-key, like an end-of-school slap and tickle. This is intense, in keeping with the rest of this New Zealand tour, played in front of an Old Trafford crowd that is invested in the action. Sunshine, fire and music, makes this not only cricket, but unmissable entertainment."
Ross Taylor doffs his cap to the crowd at the end of the over to see if they want to top up his match fee.
Not a lot of loose change, but a lot of appreciative laughter.

"It seemed to bounce on Morgan more than he thought. You can see New Zealand were trying to give Morgan no room and it worked."
Eoin Morgan has not timed that at all.
The skipper hooks hard, but high and Ross Taylor, who has been bantering back and forth with the crowd out there, takes the catch off his knees at deep square leg.
Paul McClure:, external Caught out following the cricket on holiday! You've got me in the bad books.
Apologies for that Paul...
Nathan McCullum shots a dirty look down wicketkeeper Luke Ronchi's way. The back-stop is standing right up close but allows a meat-and-potatoes off-break to slip through his gloves and for five wides.
But, overall, New Zealand have look a lot less generous since they brought more spin into the equation.
Jock Dawson on text: My 4 boys are just getting into cricket and boy are they (and me) reaping the benefits. I look forward to a fantastic summer based on England's recent performances. I would also like to credit NZ with adopting a fantastic attacking style of cricket across all forms.
Joe Root gets his pint-sized frame up on tip-toes to clout a hooked four off Matt Henry.
But that is the main bit of damage from the over. Better again from New Zealand. Halfway point and England are on target for a 170 total at the current rate.

"It spun quite a lot. A fantastic delivery. McCullum has come in and slowed the run rate down by taking wickets."
Jonny Bairstow is absolutely flummoxed in the flight by Mitchell Santner. Totally deceived and after the weekend heroics, Bairstow is only in for a short stint this time.
New Zealand hauling this match back to somewhere a bit more comfortable for them.
Jonathan Trott
Ex-England batsman on BBC Test Match Special
"Very good catch. Never easy picking up a white ball in the blue sky. A wicket New Zealand desperately needed."
Alex Hales heaves his arms - attempting a straight drive - but he is a little over-eager getting into that one. He has scooped it high in the sky and skipper Brendon McCullum keeps his eyes on it to claim a good running catch.
