What an afternoon of contrasts.

Just after lunch Durham were 22-3 in their second innings and only led Notts by 85.

Now they close nearly 400 in front. David Bedingham has a career-best 180 and Ned Eckersley has 113.

Their fifth wicket partnership is 254, a best for that stand for Durham v Notts.

It has been an incredibly one-sided day when initially it looked anything but.

And we're all done for the day in Nottingham.

Durham have dominated this one since just after lunch.

David Bedingham (180 not out) and ned Eckersley (113 not out) have added an unbroken 254 for their fifth wicket to put them 395 ahead.

They will look to press home for victory on the final day.

Floodlights switched off at 19:00 BST as is the playing condition and the umpires waste no time bringing the players off.

Hampshire will have to return tomorrow to wrap up their inevitable innings victory.

18:56 BST 10 April 2021

Durham (330 & 308-4) lead Nottinghamshire (267) by 371 runs

Century for Durham's Ned Eckersley as they continue to make Notts toil.

It's come off 121 balls and included 11 fours as he and David Bedingham (172 not out) keep on building this mammoth fifth-wicket stand worth 230.

Into an extra 30 minutes now between Leicestershire and Hampshire as they bid to get this one done tonight.

I'll be amazed if they get all the way through to 19:20 BST for two reasons: Leicestershire's tail and the light itself.

Still playing under darkening skies at Trent Bridge and Grace Road, but I'm not sure for how much longer before the umpires intervene...

18:40 BST 10 April 2021

Durham (330 & 287-4) lead Nottinghamshire (267) by 350 runs

David Bedingham's impressive knock continues for Durham as he passes 150.

Follows that up by smashing Steven Mullaney for a straight six to take his side's lead past 350 too.

Brad Wheal strikes again for Hampshire as he yorks Callum Parkinson and pins him on the boot.

Parkinson on his way leg before for 31 and Leicestershire are all but done in this one.

Stumps at Chelmsford where the day has undoutedly belonged to Jake Libby (141 not out) and Ed Barnard (116 not out) and their so far unbroken seventh-wicket partnership of 205.

They close on 350-6 and are 140 behind Essex after avoiding the follow-on.

Hampshire almost over the line at Grace Road as they pick up a seventh wicket in Leicestershire's follow-on.

Brad Wheal has Lewis Hill caught in the gully by Ian Holland for 65.

They could wrap it all up this evening with 10 overs still due to be bowled plus the option of an extra half hour.

Another sumptuous off-drive from Ed Barnard off Jamie Porter takes Worcestershire past the magic number of 341 that they needed to avoid the follow-on.

Their seventh-wicket partnership also worth 197 now as we move into the last five overs of the day.

18:07 BST 10 April 2021

Durham (330 & 215-4) lead Nottinghamshire (267) by 278 runs

Runs keep flowing for Durham at Trent Bridge.

Ned Eckersley reaches his half-century off 78 balls, including six fours as his partnership with David Bedingham (128 not out) rolls on to 137 for this fifth wicket.

Durham's overall lead pushing towards 300 now.

18:00 BST 10 April 2021

Worcestershire (332-6) trail Essex (490-9 dec) by 158 runs

Brilliant moment for Worcestershire all-rounder Ed Barnard as he reaches a maiden first-class century!

He clips Jamie Porter behind square and sprints back for two runs to take him there and punches the air with delight.

It's come off 168 balls and included 15 fours and he surpasses his previous career-best score of 75 in style.

The umpires have had a look, but with a bit of drizzle still in the air they've decided to call it off for the day.

Somerset will need 173 more runs for victory on day four.

Middlesex require seven wickets.

They're off at Northamptonshire.

Northants just brought up their third batting bonus point as they went past 300, with Rob Keogh unbeaten on 66.

All over for the day at Edgbaston.

Those rain showers midway through the afternoon have stopped Warwickshire's victory charge in its tracks...for now at least.

And with the rain falling, that is indeed that for day three.
