Adeel Malik is back in the hutch without facing a ball, run out after Ryan ten Doeschate decides he needs to keep the strike and leaves his partner stranded well short of his crease.

OptaJim: "455 - The 455 runs scored by @surreycricket and @GlamCricket is the highest match aggregate in English T20s. Blasted."
Kent can ill afford five wides from the first ball of the over as wicketkeeper Sam Billings fails to gather David Griffiths' opening delivery, but the strong arm of Matt Coles gives the home side a boost as his throw arrows in over the stumps from the deep and Matt Machan is run out - 22 needed by Sussex from 12 balls.
Australia seamer Clint McKay is brought on to try to send this game back in Leicestershire's favour, but Steven Croft and Alex Davies see him off for now. This partnership for Lancashire is now worth 46 runs off 4.5 overs.

Jack Leaning finishes proceedings with a four as Yorkshire cruise to a seven-wicket win over Derbyshire.
Seventeen-year-old debutant Matt Fisher registered the third best T20 bowling figures for Yorkshire as Derbyshire crumbled to 128 all out in 18.2 overs.
Despite losing Andrew Hodd to the first ball of the innings, an aggressive 41 from captain Andrew Gale and an unbeaten 40 from in-form Jonny Bairstow saw Yorkshire home with 20 balls remaining.
Jack Leaning is another one of Yorkshire's promising youngsters. He's currently 14 not out from 11 deliveries, with Jonny Bairstow continuing his excellent form with an unbeaten 39. Yorkshire need just four runs off four overs for a comprehensive victory.
Steven Croft with a massive blow over mid-wicket. BBC Radio Lancashire's Scott Read describes it as being "boshed" for six. Lancashire gaining some momentum.
It's almost over at Headingley as Jack Leaning flicks Mark Footitt over backward square-leg for his first six of the night. Derbyshire were celebrating as they thought they had Jonny Bairstow caught at mid-off but the umpire judged it a no-ball for height.
A much better over for Kent, with only six runs added by Sussex and more importantly, Mahela Jayawardene only able to collect a couple of singles - 38 from 24 balls needed by the Sharks, the T20 winners in 2009.
If Essex are going to win, it is going to be down to captain Ryan ten Doeschate. The Dutchman has 33 off 25 balls, but struggles to get Chris Wood away. Callum Taylor, aged 17, takes a couple of Wood's fourth ball to bring up the 100.

Earlier, Chris Nash made 61 off 45 balls with 10 boundaries. Kent spinner James Tredwell has left the field after completing his four overs for figures of 1-32.
It's over at The Oval, where Glamorgan have beaten Surrey by 25 runs.
A sparkling batting display, spearheaded by Jacques Rudolph (62) and Colin Ingram (91), put Glamorgan well in control. Their 240-3 is the fourth-highest total ever scored in domestic T20 cricket in England.
Surrey gave it a go in reply, Steven Davies and Zafar Ansari both passing 50, but they fell short of that daunting total.
In total, the crowd saw 455 runs - they certainly got their money's worth in south London.

James Foster and Ryan ten Doeschate will need to be there close to the end if they are going to pull off a victory.
Kent pace bowler Matt Coles gave away 17 in his first over, but returned to bowl Chris Nash for 61 to reduce Sussex to 118-2. With Mahela Jayawardene still in and eight wickets in hand, you would fancy the Sharks to chase down the 64 runs they need off the remaining eight overs.
