That may very well be all for this game.

Great fightback from Hampshire after being bossed by Surrey for much of the match.

Brilliant century from Nick Gubbins and Toby Albert is 77 not out.

Maiden over from Liam Guthrie.

We are very likely to be into draw territory here.

Another over from Calvin Harrison and his first ball is hammered into the off side by Tom Bailey who declines to run.

Five close catchers in. Bailey blocks down the ground, then tries to force the fifth ball away off the back foot - picked up at cover.

It's a bit gloomy here now and the floodlights are on.

Spinners only from here, probably.

Big shout for lbw as Ben Raine thumps Michael Booth's pads infront, but the umpire thinks that's taken the edge on the way through, and for what little it's worth, I think he's right.

Another edge earns Booth a single.

23 needed.

That declaration from Durham certainly made a game of it.

We talked about if they should have done it, but those extra 25 runs could be massive.

The last hour is signalled.

Matty Potts gives up a solitary single as Michael Booth carves away to Ben McKinney at deep point.

Booth moves to 33* with Ethan Bamber on 13* after another swing and miss.

24 to win.

Hampshire would need about seven an over from here and remember, Surrey could put every fielder on the boundary in this format if the team chooses to do so.

Tom Prest keeps the strike with a nudge behind square leg off Kemar Roach for one.

82 required.

Pause in play here at a less than ideal time for Northants, with precious little time to force a result.

Tom Bailey has picked up a finger injury facing Liam Guthrie but he's ready to continue. He sees out the over.

Calvin Harrison (7-118) is in his 56th over and John Turner blocks down the ground.

The third ball is edged over Rob Keogh behind the bat for one.

Five close catchers in! Five. Over bowled. One wicket left.

Michael Booth works a single off Ben Raine before an almighty play and miss from Ethan Bamber.

The next ball finds the edge of Bamber's bat but flies between Ollie Robinson and second slip and away to the rope for four. If they'd had a first slip in that should have been caught.

Two dots from Raine complete the over.

25 needed to win. Or two wickets.

Four more runs to Prest, driving Matt Fisher through cover point and Toby Albert gets a four of his own, flashing a drive and edging wide of the keeper off Kemar Roach.

Is this on? 13 overs?

Emilio Gay makes a fine diving stop at backward point to deny Michael Booth what might have been a couple of runs from the second ball of the over before Ollie Robinson stops a certain four byes as he dives to his left to parry an errant leg-side delivery from Matty Potts.

Booth scampers through for the single before Potts beats Ethan Bamber's outside edge with the final two balls of the set.

30 to win...

Ethan Bamber runs the first ball with the fresh cherry down to third for a single off Ben Raine, who has 4-59 already.

Michael Booth blocks his first ball and then gets a whack on the hand with the next as he defends it away.

The fourth ball is clipped into the leg side for a single before Ethan Bamber sees out the over.

Matty Potts will take the new ball from the other end.

Brooke Guest takes a single off Logan van Beek to reach a half century before the handshake comes on this match which surely cannot be far away. Derbys are still 173 runs away.

Eight runs off Kemar Roach's latest over so don't completely discount a Hampshire surge.

Lovely shot by Tom Prest in that over, driving past the outstretched hand of Roach through long off for four.

Perhaps a last throw of the dice for Northants as Liam Guthrie comes back on to bowl.

Tom Bailey does well to dig out a toe crusher with a thick edge.

He's faced more than 50 balls now.

11 overs left. Lancashire lead by 78.

Ethan Bamber swats the ball uppishly through the covers and the ball just beats the sprinting fielder to the rope.

36 required.

Bamber and Michael Booth collect well-struck singles to the deep to tick the scoreboard along before Bamber leans on his defence for a couple of balls before carving to backward point for a single to keep strike again.

33 to win. And the new ball will be taken... by Ben Raine.

40 needed for a Bears win after Ethan Bamber dots a single down into the leg side and dashes through to keep strike.

The final over with the old ball, which will be delivered by Brendan Doggett.

"What a loan signing. Inspired."

At the end of that over, here are the match figures for Calvin Harrison:

That's a big moment in this game.

There are still worries about what the tail of this team can do.

They can do a job for their team if they're sensible at two runs an over. The new ball is due very soon, which will see Ben Raine come back into the attack.
