A late burst from John Hastings helped Durham to 182-4 against Yorkshire at Chester-le-Street.

Hastings' powerful hitting, including a huge six into the stands off Matthew Fisher, brought him 37 not out off 16 balls and helped the home side set a testing target.

Liam Plunkett picked up two wickets against his old club, but Tim Bresnan was expensive, conceding 21 runs from the final over, including three boundaries and one six.

Marcus Trescothick, who actually has a higher strike rate in T20 cricket than Chris Gayle, hits Reece Topley for three fours in his second over.

After slamming one to the mid-wicket fence, he gets lucky as a top edge flies over the keeper.

At the other end, Gayle is on 3 off 11 balls.

David Masters bowls another tight over for Essex as Chris Gayle is kept quiet once again.

Masters, who is no more than a medium-pacer these days, even beats Gayle with the final ball.

Chelmsford is expectant, Gayle looks as relaxed as ever.

Despite a valiant 63 from 47 balls by Moises Henriques, Surrey were unable to chase down Kent's total at Beckenham.

Chasing 194 for victory, they lost two wickets in the first over and the run-rate continued to climb from then on.

Cameos from Kumar Sangakkara and Henriques gave Surrey some hope, but two wickets from Matt Coles and Fabian Cowdrey ensured Kent bounced back from Thursday's chastening defeat at Middlesex in fine style, thanks mainly to Sam Northeast's 96 off 47 balls.

"Birmingham Bears are making light work of their chase here at Wantage Road.

"William Porterfield is leading the chase and has played a combination of classic drives and more aggressive one day shots and has moved swiftly to 24. Tom Lewis has come to the crease with intent and they've just brought up the 50 from eight overs."

"There's an almost ironic cheer from the home fans as Mark Wallace hits only the second boundary of Glamorgan's innings in the sixth over.

"At 23-3, the hosts' attempts to reach their target of 149 have not started well.

"And with the temperature dropping in Cardiff, those inside the ground are beginning to lose heart."

Erm, where's Chris Gayle?

The West Indian fails to score off his first five balls before knocking Reece Topley for a single on the off-side.

I'm not sure it will stay that mellow, but what a start for Topley and Essex.

Mark Wallace decides attack is the best form of defence and slaps West Indian fast bowler Fidel Edwards for a maximum.

Jacques Rudolph, meanwhile, has scored just eight runs from 15 deliveries, but Glamorgan are surely better set with the experienced South African at the crease.

"That was absolutely magnificent from Middlesex. Everything is going well for them so far this season, they are on a high.

"They look a big threat in the competition this year.

"This is a great wicket. It's a really, really good surface, so credit to the groundsman.

"Sussex are certainly not out of this game yet but I am a little bit disappointed with their execution of skills tonight."

Durham are limbering up for a big finish at Chester-le-Street. They've kept the scoreboard ticking over with plenty of singles, but they will need some firepower in their final overs.

Liam Plunkett has returned to the attack and Paul Collingwood hangs back from playing two quick deliveries. Glenn Maxwell isn't so lucky - his second ball is lofted by Collingwood for six as Maxwell's third over flies away for 17.

Plunkett has the last laugh, however, as he clean bowls his former skipper for 32.

The visitors just appeared to have had a profitable powerplay when Rory Kleinveldt induced an edge from Bears' captain Varun Chopra with Adam Rossington taking the catch behind the stumps.

Tom Lewis, playing just his third T20 match, joins Will Porterfield in the middle.

Middlesex achieve their highest total in T20 cricket as Dawid Malan finishes unbeaten on 115 - beating their 213-4 at Old Deer Park in Richmond against Glamorgan in 2010..

The left-hander struck three sixes and 14 fours in his 64-ball effort and it will take something really special from Sussex Sharks to reach that target, but with the likes of Luke Wright and Mahela Jayawardene in their side, they have the men to provide it.

A seventh T20 half-century for Moises Henriques, who is keeping Surrey in this game.

He's been joined at the crease at Azhar Mahmood, who is throwing his bat at anything and everything. He charges down the wicket to loft Fabian Cowdrey for six before crashing the same bowler through the covers.

Mahmood however tries to play one big shot too many and Calum Haggett has him caught on the boundary for 18 from just seven balls. Henriques is joined by captain Gareth Batty.

Alfonso Thomas has just taken three wickets in the final over as Essex's innings came to a bit of a standstill in the final few overs.

After Jesse Ryder and Tom Westley put on 90 for the first wicket in 8.1 overs, I think it's fair to say the Chelmsford faithful will be a little disappointed with their team's final total.

Thomas ended with 4-37 while Jim Allenby took 3-10.

In ten minutes or so, it's Chris Gayle's turn to show us what he can do. Excited?!

I said earlier that Alex Davies would do well to get Lancashire over 120, but that's exactly what the wicket-keeper has done.

He is run out with the final ball, but only after making 41 off 26 balls.

Wayne White starred for Derbyshire with 3-21 and the Falcons will know this is a very gettable score.

"That's a richly-deserved 100 (by Dawid Malan), faultless from the very first ball that he faced.

"Yes, it's a good scoring pitch, but that has been a terrific innings."

That's a brilliant effort by Dawid Malan, who reaches his second T20 century with two runs off Ollie Robinson, who misses out on a hat-trick after dismissing Paul Stirling and Eoin Morgan with the final two balls of his previous over.

Malan, who made 103 off 54 balls against Lancashire in 2008, achieves his highest T20 score as he belts the next two deliveries from Robinson for four and six.

Big wicket for Hampshire. Chris Wood produces another breakthrough, bowling Colin Ingram for just seven runs.

Hampshire know how dangerous the South African can be and will be glad to see the back of him.

Birmingham Bears have made a steady start to their run chase at Wantage Road, with a boundary each for openers Varun Chopra and Will Porterfield.

David Willey and Rory Kleinveldt are sharing the ball for Northants and will be happy with their first few overs.

Joe Denly drops Moises Henriques - a straightforward catch that goes in and out of Denly's hands - but Gary Wilson is stumped three balls later to give Fabian Cowdrey his first wicket of the T20 season.

Kent will be pleased to see the back of Wilson and Zafar Ansari edges his second ball through to Sam Billings, who takes a fine catch, but while Henriques is still there, there is hope for the visitors.
