Short from Daryl Mitchell, it's a slower ball too but Will Jacks isn't fooled, he waits for it and crunches it over square leg for another maximum!

With the wickets in hand, and the way Will Jacks is striking, they should be looking at going for at least two runs a ball from now on.

Here is Heinrich Klaasen's one six so far. You can expect a couple more if he's out there for much longer...

Heinrich Klaasen pushes a single from the last ball of that Liam Dawson set.

We've got 30 balls left in the Invincibles innings. Plenty of time for more fireworks from Klaasen and Will Jacks.

Impact was outside the line of off stump so Will Jacks survives. His blistering innings can continue.

Have I just put the mockers on Will Jacks?

Maybe. The London Spirit go upstairs for an lbw shout as Jacks misses with a reverse sweep off Liam Dawson and is hit on the boot.

Liam Dawson is called for a wide as he tries to hide the first ball outside Will Jacks' off stump.

The next one is that bit straight but still wide of off and middled over extra cover for four.

There's no stopping Jacks at the moment.

Jacks launched that with flair. Remarkable shot.

Carved over the off side for six! Will Jacks just keeps going and keeps clearing the rope!

That is another fantastic shot.

Heinrich Klaasen thrashes at the last ball of Liam Dawson's set but this time the ball is stopped by the fielder on the boundary.

Here comes Heinrich Klaasen!

The right-hander sets himself and launches Liam Dawson back over his head for six!

Tidy stuff from Dan Lawrence. The action might be unorthodox but he was landing the ball in decent areas - keep these two batters to five from five balls between them is no mean feat.

With Jacks in the middle, Invincibles can propel themselves to a very decent total here.

A single eased to long on by Will Jacks takes him to a 32-ball half-century.

If he's still there at the end of the innings, I fancy the Invincibles will have a pretty imposing total.

Dan Lawrence is coming on to bowl his off-spin. It's some action he's got, certainly not conventional...

Will Jacks has shown his power already in this innings and with Heinrich Klaasen out to replace Jason Roy, there is no let up for the London Spirit bowlers...

Heinrich Klaasen is the new batter and gets off the mark with a boundary, slapped through the leg side!

Just a gentle, floating away swinger and Roy got a huge chunk of it. He will be irritated by that.

He was trying to drill that through the covers.

Dan Worrall is bowled out, his 20 balls have gone for 23 runs but no wickets for him today.
