Clever from Tom Curran, sending down a slower ball that Chris Benjamin can't hoick in quite the way he wants.
He gets a full toss that should only be a single but Jordan Clarke continues his horror night by falling over in front of the Hollies, and gifting the Phoenix the chance for another run.

If you had to find a weakness in the Birmingham Phoenix team it might be their batting depth.
It is isn't the strongest from the middle order down.
Phoenix 143-4
30 runs needed
Tom Curran runs in - and then stops. He gets a boo from the Edgbaston crowd for his troubles.
The boundaries have just dried up...

I like this from Saqib Mahmood and Sam Billings. They have looked to attack Benny Howell as he's come in.
Phoenix 139-4
34 runs needed
That was a very good set of five from Saqib Mahmood - a wicket and two dot balls.
Phoenix 138-4
35 runs needed
A promotion up the order for Benny Howell, then, and he's beaten all ends up by Saqib Mahmood to start.
New batter: Benny Howell

It is fantastic to see everybody on their feet. It is great to hear. That is what this tournament is about.

That has subdued the Birmingham crowd.
What an innings. Moeen has royally entertained. He is getting a rapturous applause.
WICKET
Moeen c Curran b Mahmood 49 (Phoenix 138-4)
Moeen falls!
The Birmingham Phoenix captain gets a standing ovation as he holes out to Tom Curran in the deep. What a knock. But Phoenix need someone to take this home now...
Phoenix 138-3
35 runs needed
Saqib Mahmood returns, and his first ball is smacked back over his head for four by Moeen Ali! It's so, so good.

It is time for us to take a deep breath. Those were two big sets for Birmingham Phoenix.
Phoenix 134-3
39 runs needed
What a chase this has been.
Moeen Ali is 45 from just 24 balls, with Chris Benjamin 10 from four. A massive 10 balls just now for the home side.
Phoenix 132-3
41 runs needed
I love Moeen Ali.
Mind you, Chris Benjamin isn't letting him have all the glory - he's just reverse-swept Sunil Narine gloriously for four!

Wheen Moeen Ali is in this mood there is no ground in the world that is big enough.
Phoenix 127-3
46 runs needed
Sunil Narine is back...
...and he's been absolutely launched for six by Moeen Ali! Three in a row!

It is flat and it is brutal. The supporters have rushed over to the bowls and Moeen Ali is taking this game away from Oval Invincibles...

Moeen Ali is a class player. That was a massive set for Birmingham Phoenix - they are pushing ahead.
