A sloppy over from Sri Lanka - disappointing.
Hmmm. Are Sri Lanka just starting to slip up?
A no-ball from Lahiru Kumara gifts Glenn Phillips a free hit.
A much-needed boundary for New Zealand as Phillips pulls a short ball down to fine leg.
He can be very dangerous. Sri Lanka will be crossing all their fingers and toes that the dropped catch won't cost them too much.

A simple simple catch. Hasaranga can't believe it.
NZ 30-3
Ohhh, no. The first blemish from Sri Lanka this morning and it's a pretty bad one.
Glenn Phillips tries to hit Hasaranga over the top, but finds long-off. It's literally straight into the hands except... it's not. Pathum Nissanka spills it and there's that eerie silence from the fielding side whenever someone drops a sitter.
How costly?
Here comes the fun.
Wanindu Hasaranga, Sri Lanka's flamboyant superstar, is on with his leg-spin.
An earring in one ear and tramlines shaved into his hair, he's ready to play some tricks on New Zealand's batters.
Credit to Sri Lanka, they have bowled beautifully.
The powerplay ends and it's probably everything Sri Lanka would've hoped for and more.
But we know how this New Zealand team will react. They won't back down.

Glenn Phillips timing that to perfection. He's found that gap. He's played it almost like a cut drive.
Glenn Phillips is throwing a few punches back, amid the chaos.
More lovely timing, carved past point for four.

New Zealand are thinking if we can get up to that 130-140 they have the bowlers to defend it. But they have got to get there.
Sri Lanka keep squeezing. Just four singles from Theekshana's over.
Daryl Mitchell is the new batter, who I watched bat for what felt like the entirety of England's Test summer.

All credit to Sri Lanka when you think about the resources they are missing from their seam attack. They have done a really good job creating problems for New Zealand.

Well, well, well. New Zealand are in trouble here. They've lost three wickets in the first four overs of this game.
They thrashed Australia, haven't played since and it's showing.
Williamson c Mendis b Rajitha 8 (NZ 15-3)
Another! Who saw this coming?!
A full-length ball encourages Kane Williamson to drive but he's only able to edge it through to the keeper.
Sri Lanka are on fire!

That just shows how small the boundary is. There is a fielder there two or three yards from the umpire and the fielder couldn't do anything about it.
Oh, the timing.
Kasun Rajitha drops one a bit too short and Williamson pounces, pulling through mid-wicket for four.
Here's how Maheesh Theekshana spoiled the Finn Allen party.

Lovely shot from Phillips to open up his scorecard off the backfoot. Once you get it through the infield it will race away for four. That's what you get with the short boundary.
