We hit halfway - and this one really could go either way.
Tabraiz Shamsi has gone for just four off his first five balls.
With Chris Lynn so well set, who would call it?
Big lbw shout against Chris Lynn - but he immediately reviews. And he was right. He got an edge.

Sandeep Lamichhane, the Nepalese spinner, was supposed to play for Oval Invincibles but had visa issues, so that's why Shamsi has stepped in.
Chris Lynn looking useful on 26. Harry Brook on 9. This is nicely poised.

Why on earth are the crowd singing about the darts player Michael van Gerwen?!
But, when Jordan Clark comes on, he is slapped to the point boundary first ball by Harry Brook.
But he then has a big lbw shout turned down against Brook with his second.

Chris Lynn will look to keep the foot on the accelerator so this is going to be an exciting passage of play.
Sunil Narine completes his second five. Just 11 off them,
Chris Lynn punishes a full toss with his second four.

There's no mystery about Chris Lynn here - he's clearing the front leg and trying to smash it.
Lauren Winfield-Hill
Northern Superchargers' women's captain on BBC Radio 5 Live Sports Extra
I love that from Chris Lynn - it was a show of intent from him.

That six came down with snow on it!
Chris Lynn goes aerial. His second boundary. His first six.
Powerplay over. It's gone about as well as the Oval Invincibles' did earlier.

I'm slightly disgruntled by Harry Brook's pads - he can't get the right shade of purple to match his kit.
Lauren Winfield-Hill
Northern Superchargers' women's captain on BBC Radio 5 Live Sports Extra
It's very much game on here now. Add two more wickets to this score, and Northern Superchargers are in trouble.
Willey b Mahmood 4
Saqib Mahmood strikes. Home skipper David Willey is clean bowled and the Northern Superchargers are in a slight spot of bother.
