Sri Lanka will be backing themselves to get 150. That is what they should aim for. This is a good batting track.

Leigh Kasperek back into the attack, and Madavi starts well, smashing the former Scotland spinner through the covers for four. Some good hustle brings four singles - Sri Lanka are four short of a century.

Harshitha Madavi, another leftie, out at number four. Having removed the dangerous openers, can New Zealand put the brakes on?

Atapattu is livid with herself. If she went through with the shot, that would have sailed over the infield. Instead, she checked herself.

What's going on here? Atapattu plays the ball back to Tahuhu. New Zealand claim a caught-and-bowled, Atapattu claims a bump ball, and the umpires aren't sure - ump Sue Redfern goes upstairs to her colleague...

It's a change of ends for Lea Tahuhu - can the NZ pace spearhead be inspired by switching to the end associated with the great Dennis Lillee? Not by the look of it - as she starts by firing down a couple of legside wides. Sanjeewani helps herself to a two and a single.

Atapattu's innings is a bit binary at the moment - she's either playing and missing, or hitting boundaries?

The fifth ball of Jensen's over is a play-and-miss. The last is lofted over square leg for Atapattu's fifth four. The Sri Lanka captain has 41 from 28 balls.

Here's the only wicket to fall so far:

Sanjeewani tips-and-runs a single, fortune continues to favour Atapattu as a flashing outside edge goes to third man for a single. Jensen tries a shorter delivery which Sanjeewani pulls for one.

And here's the first of those sixes from Atapattu:

As we reach the halfway stage in Sri Lanka's innings, here's what you missed by not being with us at 07:00 GMT for West Indies v Thailand...

Atapattu rides her luck a little, with a play-and-miss while also profiting from a misfield. But Sri Lanka reach the halfway stage of their innings with only one wicket down - can they be looking towards a challenging score like 140-150?

It's not easy to sweep at the Waca because of the bounce, but these two have played it particularly well.

Atapattu gets down on one knee and slog-sweeps Amelia Kerr over square leg for another massive six - which is measured at 70 metres. That's six, even if they were playing with the men's boundaries.

I love the Sri Lanka intent. It's not just about fours and sixes, you have to run well.

Hayley Jensen is New Zealand's sixth bowler in the space of nine overs. From the Kiwi production line of right-arm medium-pace seamers. And after Sanjeewani steers her first ball for two, there's a big, big, long, confident appeal for lbw as Sanjeewani tries to force the ball across the line... but the White Ferns opt to keep their review in the bank. And the TV ball-tracker shows it was the correct decision.

A tidy over from Jensen - just three runs from it.

Anushka Sanjeewani, Sri Lanka's wicketkeeper, is in at three. She's off the mark with a single.
