Five overs to go in Yorkshire and Birmingham's Sam Hain is incredibly on 49 not out.
I say incredibly as I swear he was still in his thirties last time I checked. The Hong Kong-born batter has only hit five boundaries so far. He's scoring in twos!
Jacks run out (Green) 70 (Middlesex v Surrey 95-1)
Great fielding from Middlesex brings Will Jacks' incredible innings to an end.
It's quick work from Paul Stirling to get the ball back in from Jason Roy's reverse sweep.
Both batsmen are looking at the ball and there's a mix-up between them.
Chris Green finishes the run-out off, and Jacks is left to think about what might have been.
His score of 70 - off just 24 balls - is his best in T20 cricket.

Jacks has an incredible 69 off just 23 balls. A strike rate of 300...

And now Griffiths has his four-for.
Luke Wood didn't last long, caught for a two-ball duck.

He'll have one more over to try and hunt down a maiden T20 five-for.

The spin of Chris Green takes a bit of momentum out of the Surrey charge.

Middlesex v Surrey 68-0

He's three runs from his half-century now. It's been a fruitful powerplay so far for Surrey.
Glamorgan 41-3 v Gloucestershire 179-6
Two more wickets in as many overs for Gloucestershire.

Lancashire 110-4 v Leicestershire
Another one bites the dust.

He keeps finding the space in the field, scoring back-to-back fours, beating fielder Luke Hollman with carbon-copy shots from subsequent delivery.
The 50 is up for Surrey, and they're motoring along nicely. It's been a tough start for Middlesex's young openers.

Then he lifts the final ball of the over down to long off for four.
Jacks has 29 runs from 10 balls.
Carlos Brathwaite c & b Thompson 3 (Birmingham 73-5)
Another international falls.
A leading edge sees the ball loop back to bowler Jordan Thompson as West Indian Carlos Brathwaite walks for three on his Birmingham debut.
Not great from the Bears who are scoring freely, but regularly losing wickets. 9.3 overs gone so far.
Middlesex v Surrey 24-0
Blake Cullen is also making his T20 debut for Middlesex.
The 19-year-old's shirt number matches his age.
After a single for Jason Roy, a wide and a leg bye, there's another genuine edge which goes to the boundary
Roy is the beneficiary this time.
The visitors finish the over with three singles.
