West Indies all-rounder Deandra Dottin, who took 2-21 last match, is about to run in for the Originals.
Originals' Emma Lamb gets some joy with some slower bowling, conceding just two runs off her set.
Much more like it for the visitors.

The best part is they are very constructive, very well-measured and controlled.

That completes the powerplay for Southern Brave, they're really motored away after the first three sets.
Mandhana 30, Wyatt 12
The powerplay finishes with another Smriti Mandhana four straight down the ground.
The Brave are cruising and in control.
Three runs from the first three balls.

Always a good battle when these two come up against each other, Ecclestone to Wyatt.
The Originals need to slow things down. They turn to star spinner Sophie Ecclestone.

Just as we said they were struggling to find any rhythm, they have now got three boundaries. Mandhana's ticking.
The fours keep on coming!
Mandhana chops one over the offside for another boundary before finishing the set of five with a pull for four.
The Brave are finishing off the powerplay in some style.
Mandhana 16, Wyatt 11
Next ball, tickled fine for four. Mandhana is accelerating. She's on 16 off eight now.

That's cleared the advertising board! That's her get-out-of-jail shot, clearing her front arm.
Oh that is huge!
Lea Tahuhu continues and Smriti Mandhana picks her, launching a six over the top into the stands.

I think it's been really good bowling so far from the Originals. Good, tight bowling.
Still, a very tight five balls from Grace Potts, just two runs from her set. The Originals have started well after winning the toss.
Brave 15-0
No chance. Mandhana is well in her crease.

Stumping appeal has been sent upstairs mainly as a precaution. One thing about The Hundred is they get through umpire reviews really quickly.
Brave 15-0
Grace Potts is thrown the ball next as Manchester Originals continue with pace. She beats Smriti Mandhana with a slower ball and, hang on, is this a stumping chance? We go upstairs...

Long chase there for Tahuhu, especially after having bowled her set. Danni Wyatt still not as comfortable but that's four nonetheless.
