Kent 191-4 v Surrey 18-0 (1 over)
Will Jacks on a mission it seems to try and chase this down for Surrey at Canterbury.

Birmingham 34-5 (7 overs) v Notts 177-9
Notts' Steven Mullaney saluted the crowd in celebration after a comfortable catch from Matt Lamb's drive.
Lamb went out for 4 after a second wicket in a matter of minutes from the impressive Jake Ball.
Birmingham's Rob Yates is trying to steady the ship with a score of 14 at Edgbaston, but being the first man in double figures for the Bears is just a small consolation.
It's going to take something very special from Birmingham now.
Yorkshire 180-4 v Lancashire 45-3 (7 overs)
Adam Lyth returns to offer up a few teasing tempters.
Keaton Jennings finally times a reverse sweep and finds the boundary - but it's the only one in the over as Lancashire add 10 to their total.
Yorkshire 180-4 v Lancashire 35-3 (6 overs)
Lockie Ferguson is already working up a head of steam and there is only a single from the final three deliveries of his over. Lancashire need 146 more from 84 balls to get the job done this evening.
Worcestershire 167-6 v Derbyshire (20 overs)
Worcestershire will be very pleased with that innings.
43 for Brett D'Oliveira, 37 for Ross Whiteley and 30 for Ben Cox were their biggest scores as Derbyshire now chase 168.

Yorkshire 180-4 v Lancashire 34-3 (5.3 overs)

Yorkshire 180-4 v Lancashire 32-2 (5 overs)
Keaton Jennings has a rueful smile on his face as he middles a stroke into the off side, but it's straight at Mark Stoneman.
He tries to ramp the next delivery and is lucky it misses the stumps and he fails to make any contact.
The final delivery is mis-fielded by Stoneman but Lancashire don't risk a run. Four dot balls end the over.
Birmingham 18-4 (4 overs) v Notts 177-9
A terrible start to Birmingham's chase at Edgbaston.
The Bears' Will Rhodes and Sam Hain haven't been able to repeat their earlier heroics as fielders, with Notts' Jake Ball racing to make a good catch from Hain's sweeping drive.
He's out for 5, which equals the best score managed by a Birmingham batsman thus far.
Yorkshire 180-4 v Lancashire 32-2 (4.2 overs)
The first bowling change by Yorkshire and Matthew Waite's opening delivery is lofted for six by Alex Davies. The second, though, may be fractionally slower and this time Davies cannot clear long-on. A waste of a wicket from Lancashire's point of view.
Yorkshire 180-4 v Lancashire 26-1 (4 overs)
Only two runs from the first five balls of Adam Lyth's second over, but the last is just short enough for Keaton Jennings to swivel and pull it away for four. Lancashire needed that one.
Kent 191-4 v Surrey
Jordan Cox smashes his fourth six off the last ball of Kent's innings to finish 61 not out off 28 balls and power his side to 191-4 at Canterbury.
Jack Leaning (50), Joe Denly (36) and Zak Crawley (24) also made valuable contributions at the top of the order.
Hampshire 176-6 v Gloucestershire
Hampshire recover from a stuttering start and inconsistent middle part of their innings to post 176-6 against Gloucestershire at the Ageas Bowl.
Tom Prest finishes unbeaten on 59 off 42 balls while James Fuller chipped-in down the order with 38 off 24 balls.
Could be a tricky chase for Gloucestershire as they bid to hold on to the top four place.
Yorkshire 180-4 v Lancashire 20-1 (3 overs)
Yorkshire entrust Matt Fisher with a second over after an expensive opener and Alex Davies hammers him over long-on for six.
Davies is struck a painful blow on the elbow as he misses an attempted pull shot, prompting the team physio to come out and take a look.
The next one is a quick delivery which Davies tries to uppercut, but makes no contact.
Sussex 201-7 v Glamorgan 168 (18.4 overs)
David Wiese takes two wickets in two balls to end the game and give Sussex their fourth T20 win of the season.
They have suffered most with the recent wet weather, with five games ending in no-results, but remain in contention for the quarter-finals.
Callum Taylor skies to mid-off and Wiese then bowls Andrew Salter leg-stump for figures of 2-19. Star performer with the ball, though is youngster Archie Lenham, who claimed 4-26.
Kent 168-4 (18.5 overs) v Surrey
Jack Leaning also makes a half-century for Kent in that impressive partnership with Jordan Cox.

Hampshire 157-5 (18.1 overs) v Gloucestershire
Young Hampshire batsman Tom Prest brings up his half-century off 37 balls as he and James Fuller continue to compile a useful stand for the sixth wicket.
Five fours and two sixes in Prest's half-century.
Kent 161-3 (18 overs) v Surrey
A fine half-century from Kent wicketkeeper-batsman Jordan Cox as he reaches his landmark off just 24 balls.
It's included four fours and three sixes in this superb partnership of 84 for the fourth wicket with Jack Leaning (44 not out).
