A good set of five from Dwayne Bravo, who varies the pace of his bowling. He's getting some movement through the air as well.
A huge heave from Andre Russell off his final delivery but he's unable to middle it and the fielder gets the ball back in quickly.
Five runs to the total.

Here he is. Dre Russ. £125,000 worth of West Indian beefcake.

Next in for the Originals is Andre Russell, who is arguably the best all-rounder in T20 cricket.
A powerful, ultra-aggressive batter who focuses on hitting as many sixes as possible, and a high speed fast bowler who specialises in the final overs of the game, the Caribbean star is a threat in all aspects of the game. Immensely experienced in all leagues around the world.
Russell is making his debut in The Hundred and keeps the final ball of Willey's set out.

Tight lines from David Willey. Madsen tried to use his body and hit into the off side but just picked out the extra cover fielder. A good innings, though.
That ball from Willey is exactly where you want to be as a bowler on this wicket.

Madsen b Willey c Van der Merwe 43 (Originals 100-2)
A bouncer from David Willey but Wayne Madsen use his bat like a ramp and lifts it over the wicketkeeper for a couple.
Next ball, though, he's gone for 43 off 26 balls when he smashes it straight into the hands of Roelof van der Merwe.
Originals 96-1
The shadows are lengthening at Old Trafford with floodlights on. There's something in the air.
Jos Buttler would love to get the first century in The Hundred.

We're only a quarter of the way through the game and the Win Predictor is giving Manchester Originals a 67% chance.

A well-paced innings from Buttler. He got off to a flyer then had to pull back a bit when the change bowlers came in but is back up to pace now.
Fifty for Buttler
Jos Buttler hits 50 off 34 balls, reaching it with a single off David Wiese.
Go on, double it up now, Jos!

The atmosphere inside Old Trafford is just cranking up as Jos Buttler tickles the accelerator.
Original 85-1
David Willey back but Jos Buttler is going through the gears and skewers him for four.
We haven't had a century in either the men's or women's Hundred yet. Could this be the night? Buttler looks in the mood.
Birminagham Phoenix's Liam Livingstone has hit 92 not out is the highest score in men's. Jemimah Rodrigues has the same score for the Northern Superchargers
Is that at risk tonight?

Buttler goes big. It's a massive hit for six!

That might have hit a tram! That ball could be on its way to Altrincham.

Here we go Jos Buttler! He's finally gone after Adil Rashid and it's some hit!
The England white-ball captain has gone after his team-mate and dispatched the spinner for miles back over his into the grandstands.
That was huge.

That's quite an energetic shot for two runs from Madsen.
Originals 69-1
Jos Buttler is again a little cautious to Adil Rashid, waiting to hit him low for a single. Next ball, Wayne Madsen swivels and plays a reverse pull which brings him a couple more runs. Inventive stuff.
Originals 65-1
David Wiese, who could be a stunt double for the actor Antonio Banderas in Desperado with his long hair tied back, is through five balls quickly with just five runs taken from the,.
Rashid is back on to bowl. Will Buttler be bold enough to take him on this time?

A few problems for the Northern Superchargers in how to break this partnership, which looks pretty good.

Oh no. It's the longest part of the ground. You could see Madsen watching that shot expecting it to go for four, if not six. In county cricket, when you talk to the Lancashire bowlers, if there is one player they hate bowling to, it's Wayne Madsen.
