Alex Davies tries to pull away, but throws it bat away in the process too. The ball loops down down to Chris Wood at fine leg, who should take a simple catch, but drops it.
That is really poor.

Just beautiful.
Brave 39-2
Excellent stuff from Blake Cullen with just two runs coming off his first set of five, alongside that wicket.
He's going to continue as well...

Wonderful start from Blake Cullen. He's up at 80mph into De Kock and that's a big scalp for him. Great to see a young player coming into the attack and making an impact straight away.
Next batter: Devon Conway

Quinton de Kock c Rossington c Cullen 37 (Brave 36-1)
Cullen strikes first ball, and it is the BIG one!
Quinton de Kock tries to pull away, but gets a top edge straight up in the air. Wicketkeeper Adam Rossington ushers everyone out of the way, steadies himself, and takes a simple steepling catch.
Spirit have made a good start.

Blake Cullen, who is just 19, is on.
Brave 36-1
Alex Davies looks a bit hesitant here. He's trying to guide Chris Wood down to third, rather than trying to cut or drive with any real conviction.
Wood finishes with a superb bouncer, and that's just two runs from the set. The left-armer has figures of 1-4 from his 10 balls. Excellent.

Chris Wood is back, just from the other end.

Brave 34-1
That's an excellent set for Southern Brave with 13 runs coming off the five balls.
That turns it into a decent powerplay for them. But it is honours even so far.
Brave 33-1
This small boundary isn't big enough for Quinton de Kock.
Mohammad Nabi drops a little bit short, and de Kock just whips it over square leg for his second six.
Beautiful shot.
Brave 25-1
That is a shot!
Quinton de Kock gets down on one knee and crunches away a sweep to the boundary.
He timed that beautifully.
Post update
Mohammad Nabi is going to complete the 25-ball powerplay.
This will take him to ball 15 of his 20-ball allocation.
Brave 21-1
Alex Davies gets off the mark with a nudge round the corner.
It has been a relatively sedate start so far.

You could see the intent from James Vince but he falls victim to Chris Wood. He was trying to target that boundary but the length was good and it was a fine catch from Mason Crane.
Next batter: Alex Davies

Vince c Crane b C Wood 6 (Brave 19-1)
Breakthrough!
James Vince is tempted into the short leg-side boundary, but he doesn't quite connect with it cleanly, and Mason Crane does well to run out and take a low catch.
It's another piece of superb field placement by Eoin Morgan. That's a big wicket for the Brave.

That is an unbelievable shot. It's not a bad ball from Amir, he offered a little bit of shape, but De Kock just opened it up. A beautiful shot.

It will be left-arm seamer Chris Wood from the other end.
