Ex-India seamer on BBC Test Match Special
It was a hot, muggy day. The air is thicker, so perfect for swing bowling.
Target 128
Rachel Priest, who has been prolific in T20 franchise leagues and recently recalled to the New Zealand side, takes guard but plays and misses as Prabodhani whistles one past her outside edge.
Target 128
New Zealand are on the scoreboard with a legside wide which swings just past Devine's attempted leg glance. The White Ferns skipper attempts an on drive, but gets an inside edge for a single.
Sophie Devine and Rachel Priest opening up for New Zealand. Udeshika Prabodhani, a canny, veteran left-arm seamer in the style of her compatriot Chaminda Vaas, takes the new ball. Here we go.
If Sri Lanka want some inspiration from their men's team, they've just beaten West Indies in an ODI at the SSC in Colombo.
So, 128 needed - at a round 6.4 runs per over.
New Zealand, on paper, bat deeper than Sri Lanka. But the game's not played on paper...
Bowling figures are worth a look here - Jensen equalled her best T20 bowling figures by taking 3-16, Amelia Kerr 2-21, and Lea Tahuhu 1-18, all from four overs.
A stat you'll see in Stephan's match report - Sri Lanka only added 40 runs, for the loss of six wickets, in the last 8.2 overs - Atapattu being the first of those six.

Sophie Devine is thriving as captain. I think New Zealand will chase these in 18 overs.
Both these sides have openers in top form - Chamari Atapattu is crucial to Sri Lanka's chances, but Sophie Devine had an absolutely phenomenal time in the recent Women's Big Bash League in Australia.

I don't think it's enough. After the start they got, Sri Lanka should have posted at least 140. Atapattu can't do it all herself, others have to step up.
Is it enough?
After the tremendous start Atapattu gave Sri Lanka, I wonder if they're about 10-20 short.
Madavi swings high into the night, it sails over the keeper's head, but she comes back for the second and pulls out a full-length dive to make sure New Zealand will need 128 to win.
Kulasooriya manages to get her established partner on strike. What a great over this has been.
Madavi rotates the strike. Left-handed Achini Kulasooriya will face with two deliveries left.

I'm really impressed with Jensen. She's bowled really well on this pitch.
Dilhari c Tahuhu b Jensen 3 (SL 123-7)
Dilhari lobs an easy catch to Tahuhu running round at cover. Jensen is on for career-best T20 figures here, she has 3-12 with three balls left.

New Zealand would take a run a ball from here.
Jensen bowls. Single. Single. Four balls left.

Hayley Jensen's bowled well - she's going to bowl her last over now. You have to say the momentum's with New Zealand now, and that means a lot in T20.
