An easy catch and Sutherland has to go on the first ball. Another wicket falls in quick succession for the Welsh Fire. They really are crumbling here. Manchester Originals coming back very strong into this game.
Target 157
Fran Wilson smashes the hat-trick ball away for four.
What a game Deandra Dottin is having though, 67no with the bat, 2-20 with the ball.

Golden duck for Annabel Sutherland!
Deandra Dottin on a hat-trick!
Sutherland lofts a gift up to Amy Satterthwaite at backward square leg.
Haynes c Potts b Dottin 11 (Fire 123-2)
Now then.
Full toss from Deandra Dottin and Rachael Haynes tries to attack it but fires straight at Grace Potts who holds on at extra cover to make up for that earlier drop.

Welsh Fire are still in this game. If Potts had caught that, Beaumont would have been out. That's the thing about cricket, these small moments can change things.
Target 157
And, of course, as is always the case in cricket, the dropped catch is punished next ball as Rachael Haynes crashes a big drive away for four.

Oh no, Grace Potts drops a great chance to dismiss Tammy Beaumont at deep extra cover.
How big could that be?

Matthews has got her team into a very strong position. But with a couple more wickets things could change.

Sophie Ecclestone gets the breakthrough and Matthews is gone! Ecclestone does it, the No. 1 in the world. Is this the time the game could turn?
It's a fine ovation for Matthews as she walks off.
Matthews b Ecclestone 69 (Fire 110-1)
And there is that wicket!
Sophie Ecclestone is the bowler to strike with a lovely delivery that befuddles the West Indies batter and strikes leg stump.
A brilliant innings of 69 comes to an end and in comes Rachael Haynes for Welsh Fire.

There's 30 balls left and 47 runs are needed. Can Welsh Fire get over the line and secure their first win in this tournament?
Target 157
Emma Lamb stemmed the bleeding for the Originals there with a decent set.
You suspect Manchester have to take a wicket if they are to win this though - they simply have to break this century opening partnership.
Target 157
Hayley Matthews gets some luck, chipping one up off Emma Lamb but short of a fielder.
An errant throw at the stumps gifts Welsh Fire an overthrow single too.

How are the Manchester Originals going to put the brakes on because this is the exact acceleration the Welsh Fire needed?
