Here's how Trent Rockets picked up their first wicket, that of India opener Smriti Mandhana.
That's a very good set of five from Heather Graham.
She starts with four singles, before Anya Shrubsole pinches a single to mid-off.

Stafanie Taylor looks to be the one who will try and get Southern Brave to a somewhat respectable score.
Wellington c Glenn b Sciver 5 (Brave 57-5)
Nat Sciver has two!
The England all-rounder is one of the best players in the world - she's the number one ranked player in the Twenty20 format, and she's taken to The Hundred pretty well so far.
Amanda-Jade Wellington tries to cut away, but she hits it straight down the throat of Sarah Glenn at point.
The win predictor is currently 69-31 in Trent Rockets' favour.
Nat Sciver has a fair bit of captaincy experience with Surrey Stars in the Kia Super League, and she was pretty successful too, so that's a plus for the Rockets.

If Johnson had any nerves before this game, taking a wicket with the first ball would have calmed her down.
That's a good set of five from Sammy-Jo Johnson with just two singles, and a wide, off it.
We're half way through. Trent Rockets will probably be the happier of the two sides so far, but Southern Brave still have a chance of reaching a significant total while Stafanie Taylor is around.
Another bowling change as Sammy-Jo Johnson returns to the attack.
Nat Sciver has stuck to five-ball sets so far. We haven't seen anyone bowl 10.

There's never a good time to lose a wicket but they were starting to build something there.
Bouchier c Higham b Glenn 18 (Brave 49-4)
Ah, that's a blow for Southern Brave. They were just starting to build.
Maia Bouchier looks to work off her legs, but she's a bit too early on the shot, and a leading edge squirts up for Lucy Higham in the covers.
The Rockets are picking up regular wickets.
Hello, Stafanie Taylor!
England spinner Sarah Glenn is back on, and she's welcomed by a thumping slog sweep over the mid-wicket boundary for the first six of the game.
That is a lovely shot.
The Trent Bridge crowd are singing Happy Birthday at the moment. There's a good atmosphere in Nottingham.

This Trent Bridge surface is one where you can score quickly in the last few deliveries. They will be targeting those last 20 balls I think.
Another boundary.
Maia Bouchier is starting to play a really significant hand here. It's a little bit wide from Kathryn Bryce and she cuts to the point fence.
She's up to 17 off 11.
Four more! That's a lovely shot too.
Maia Bouchier is well known on the domestic circuit, but this tournament is a good opportunity for her to become well known. Shots like this will help.
She goes in to out, and lifts over the covers.

That was an expansive shot, you feel Taylor is getting into her groove now. She is a destructive player.
It's time for us to see another of Trent Rockets' overseas stars in Australia's Heather Graham.
Graham has played once in one-day international cricket for Aussies.
Stafanie Taylor picks up her first boundary with a lovely cut shot. That flew to the boundary.
That'a decent set of five for Southern Brave with seven runs coming off it.
Time for a bit of a spin in the form of England leggie Sarah Glenn, and her first ball is pulled to the boundary by Maia Bouchier.
Southern Brave are going to need this partnership to go big.
Maia Bouchier, who plays her domestic cricket for Southern Brave, came in when Danni Wyatt was dismissed.
