Steven Patterson starts the over with a filthy full toss, which gets exactly what it deserves: a huge six into the Western Terrace from Steven Croft.

Unfortunately for the Lightning, Ryan McLaren is still struggling to time the ball and has just four from seven balls so far after a few singles in this over.

Adil Rashid is back into the attack and does typically well, going for just five runs from his third over.

Steven Croft sweeps well, but can't find the fence, while Ryan McLaren plays the last two balls back to the bowler. Pressure on now.

A sensational catch from Jack Leaning sent Arron on his way for for 12. Well worth another look.

Good stuff from Lancashire skipper Steven Croft, who takes a single from the last ball of the over to reach 50 from 38 balls.

He's hit five fours and two sixes and has the game in his hands now. 74 needed from 36 balls.

Samit Patel smashed an unbeaten 77 off 48 balls, with a six and 10 fours, as North group leaders Notts Outlaws moved a step closer to the quarter-finals with their seventh win. Sam Hain made 82 not out for Birmingham Bears, but their total was not enough as Notts reached their target comfortably with 11 balls to spare.

Liam Plunkett breaks the spell of spin bowling. He goes to the wide third man boundary from the first ball as Jos Buttler opens the face, but he limits the damage with a tight line and length.

The game is in the balance now, but a wicket would swing it in Yorkshire's favour, you feel.

Just a third win of the season for Durham Jets, and one which effectively ends Worcestershire's hopes of making the knockout stages of the T20 Blast. After failing with the bat, Keaton Jennings took 2-21 from his four overs of medium pace, with Ben Cox's 34 the highest score for the Rapids. Big-hitting Ross Whiteley fell to Barry McCarthy (2-32) for six.

Croft 46, Buttler 13

The pressure was building for Lancashire, but their skipper released it in the perfect way, smashing a sweep into the stands.

Adil Rashid responds with a googly that beats him all ends up, but Steven Croft keeps it out. Lightning need to get a wriggle on now - 90 runs needed off 48 balls.

Good spell by Rafiq, just 26 conceded from his four overs. The downside is that a lot of seam will be bowled between now and the end of the innings and on the evidence of the first innings, it's easier to get away. I think these two will be fancying it.

Well bowled Azeem Rafiq. Steven Croft is trying to get a move on, but he can't get the off-spinner away, with a reverse sweep finding the fielder.

Rafiq finishes his spell with a dot ball to Jos Buttler. He returns figures of 0-26 from his four overs.

Watch: Lilley smashes away for sixpublished at 21:03 British Summer Time 11 August 2017

Before he was out in the most spectacular fashion imaginable, Arron Lilley hit a remarkable six into the crowd. Take a look at the shot here.

This is the key phase of the game. Adil Rashid, Yorkshire's most dangerous bowler, is into the attack to bowl at the Lightning captain and best player.

Steven Croft gets just enough to a slop-sweep to clear the legside boundary rope, but otherwise it's a good start from the leg-spinner.

It only takes three balls for Jos Buttler to get his eye in. Azeem Rafiq tosses it up and watches it disappear over his head for a massive boundary.

Buttler is the danger man. His wicket could decide this game, which is why a mis-timed chip is met by a gasp from the crowd. Game on.

• Some innings by opener Callum Dickinson for Hampshire. His 51 took just 24 balls but he's gone now with his side on 83-1 in the seventh over, chasing 168 to beat Kent Spitfires.
• Gloucestershire's Chris Liddle has taken two wickets against former club Sussex Sharks, who are 52-3 in the seventh over after dismissing their opponents for 138.
• Essex Eagles appear to have the upper hand against Middlesex, reducing them to 49-3 in the sixth over after making 172-9 from their 20. One wicket each for Paul Walter, Dan Lawrence and Mohammed Amir so far.

Yorkshire will be the happier of the two sides at the moment but it can change very quickly.

Lancashire are managing to tick the scoreboard over at six or seven an over and one heroic over with a couple of boundaries can get them up and running.

Azeem Rafiq is back and is very unlucky not to take a wicket. He sees the struggling Arron Lilley coming down the wicket so fires a quicker one down the legside, only to see wicketkeeper Sarfraz Ahmed fumble.

Steven Croft is going well, but is batting partner Lilley is not playing up to his pinch-hitting role.

• Alex Hales went for a first-ball duck for Notts Outlaws but they are 113-3 in the 11th over, chasing 181 to beat Birmingham Bears. Samit Patel is going well with 35 not out from 26 balls at the moment.
• Adam Rossington is one run short of a half-century for Northants Steelbacks, who are 76-2 in the ninth over, needing 194 against Leicestershire Foxes.
• Keaton Jennings failed with the bat for Durham Jets but he has taken the wicket of Ben Cox for 34, with Worcestershire Rapids 99-3 in the 15th, needing another 67 to win.
