The Bears appeared to be cruising to a win over Northants, but left themselves with nine needed from Azharullah's final over.

After two wides and four singles Ateeq Javid was run out pushing for the three runs needed to win. That left Will Porterfield needing a single from the last ball of the match.

With Adam Rossington up to the stumps Azharullah's delivery ran away for four byes to give the visitors their second win of the season in dramatic fashion and leave Northants winless from two matches.

James Hildreth launches Graham Napier over square leg for six, but Napier bowls him the following ball with a wonderful yorker.

This may sound obvious, but Chris Gayle holds the key here. He's 45 not out.

Surely Derbyshire aren't going to throw this away against Lancashire - but after Tom Poynton is caught off the final ball of James Faulkner's third over, Tillakaratne Dilshan is run out for 38 by a direct hit from Arron Lilley.

The home side are still in the driving seat, however, with in-form Chesney Hughes striding to the middle to join Wes Durston.

Not the greatest start for Yorkshire as Alex Lees it caught at mid-off by Calum MacLeod for just nine. Lees was frustrated as Usman Arshad took the pace off the ball. He hammered it firmly but straight to the waiting MacLeod.

Yorkshire will need to replicate Durham's innings - play carefully and then try and blast it at the end with wickets in hand. Andrew Gale has been joined by Jonny Bairstow, who has been in fine form of late.

John Hastings has been excellent with the ball. By mixing up his paces he's frustrating Yorkshire. All going Durham's way at the moment.

Forget what I was saying about Chris Gayle playing a sedate innings - he's suddenly 42 off 36 balls.

The big man hits Shaun Tait's final ball of the over for four, as Somerset find themselves in this game.

This is why Gayle is the most wanted man in T20 cricket.

"Can't tweet as commentating! Gayle has hit two of the biggest 6's seen at Chelmsford!! 5 live sports extra now!"

There you go, we've lost our first cricket ball.

Chris Gayle slog sweeps Tom Westley out of the ground and then follows it up with an even bigger maximum into the flats.

That over has gone for 19.

We could be in for an exciting half-hour. 'Gayle Force' is here!

Having struck a four and six off Jordan Clark to bring up a 36-ball half century, Hashim Amla gets a little bit too confident. Down on one keen outside off stump and looking to flick the ball down to fine leg, he is bowled by a well pitched-up delivery.

However, with only 35 needed and over nine overs to get them in, it is only a momentary setback for Derbyshire, who still have Tillakaratne Dilshan not out at the other end and are firmyl on course for their first T20 win of the season.

The pace of Shaun Tait has worked as the Australian traps Peter Trego lbw and Somerset are in trouble.

We all know Chris Gayle can launch the ball out of the ground, but this game is slipping away from Somerset.

Does the Sussex Sharks' mascot have that sinking feeling? Not while Luke Wright is still at the crease and giving the home fans something to get their teeth into. A six and two fours in one over from spinner Nathan Sowter keeps the scoreboard ticking over, but the loss of Craig Cachopa - a second victim for paceman James Harris - was another blow to their chances of overhauling Middlesex's daunting total.

Chris Gayle is continuing his sedate innings as he pats the off-spin of Tom Westley for three singles.

We all know that can change, but it may need to quickly as Somerset need 131 runs off 12 overs.

Shaun Tait is into the attack.

Birmingham Bears have lost the wickets of Tom Lewis and Laurie Evans to Azharullah, but Rikki Clarke has joined Will Porterfield with the game tight as it nears its conclusion.

Clarke has just hooked Rory Kleinveldt over the stands for six in an over costing 12 runs, leaving the Bears requiring 34 from 24 balls to win.

Andrew Hodd has fallen early in Yorkshire's chase, trapped lbw by Paul Coughlin for just two.

Captain Andrew Gale, who has been in good form in the last few games, has been joined by Alex Lees, who is scratching around for a bit of form. Gale however is free-flowing, blasting Coughlin through the covers for four.

Durham's fielding has been excellent early on, typified by a one-handed pick up from Usman Arshad that limited a certain boundary to just one run.

Straight after the wicket of Jacques Rudolph the players are coming off in Cardiff. The covers are making their way onto the pitch, so we are in for a delay.

Glamorgan require 65 from 40 balls, but they are nine runs behind on Duckworth-Lewis method, so if there is no more play the visitors will win.

The Welsh side will be praying to the weather gods.

'Cakewalk' - it's a strange expression isn't it, given that cakes do not, as a general rule, have legs. But is is an appropriate expression to describe events at Derby where Hashim Amla and Tillakaratne Dilshan look like making short work of chasing down Lancashire's below-par total.

After initially being outscored by his partner, Dilshan produced a burst of four-six-four off successive deliveries from James Faulkner and followed that with two boundaries in the next over bowled by spinner Stephen Parry.

Chris Gayle has arrived in England everybody!

Having made just 6 from 18 balls, Gayle smears David Masters through mid-off before smashing one through the covers.

He has such tremendous power and that was demonstrated there.

Luke Wright is certainly up for the challenge but the loss of two early wickets has seriously undermined Sussex's chances of chasing down their target.

Following Dawid Malan's unbeaten 115 for Middlesex, Wright has signalled his intent with a six and a couple of early boundaries.

But opening partner Chris Nash was bowled by Kyle Abbott and, perhaps crucially, Mahela Jayawardene dollies a catch to Eoin Morgan off James Harris in the next over after making only five.

Somerset have lost their first-wicket as Marcus Trescothick gets a thick edge off Graham Napier and the ball flies to David Masters who juggles the ball before claiming the catch.

Chris Gayle is really struggling so far. He's just five not out off 17 balls.

The required run-rate has just climbed above 10.

Important breakthrough for Hampshire. After a partnership of 69 runs between Jacques Rudolph and Mark Wallace, the medium pace of Sean Ervine finds the wicket.

Rudolph aims for the legside boundary but Will Smith takes the catch and the run-rate is up to 9.5 an-over.

With batsmen of the experience of Hashim Amla and Tillakaratne Dilshan at the crease, victory should be a formality for Derbyshire after an undistinguished batting effort by Lancashire.

Amla has been the dominant partner so far, collecting four boundaries before launching a six off Jordan Clark, and it will take some remarkable bowling by the Red Rose county from here on in to deny them.
