Ethan Bamber gets down on one knee and sweeps Simon Harmer.

Dean Elgar dives over the top of the ball and it runs for four. Not so good.

Nathan Gilchrist edges Sam Cook low past where third slip would have been and gets off the mark with a boundary to third man.

Gilchrist adds a single before a Bamber edge drops just short of the slips.

The lead is 182.

Four leg byes for Lancashire after Josh Bohannon looks to glance a loose delivery from Will Williams down to fine leg.

Sam Robson picks up four off Liam Guthrie and Middlesex are in front with just one wicket down.

I think there's enough encouragement for Liam Dawson to bowl until the end.

I think if the swap does come it'll be Baker for Abbott for maybe a couple.

I'd keep Liam Dawson on for a little while.

James Rew is looking to put the pressure back on Liam Dawson but he misjudges a reverse sweep which ends up being a dot ball.

I think Dawson felt he got his man there but Rew played the ball against himself rather than on to his own wicket.

Essex are just one wicket from batting again this evening as Sam Cook completes his 15th first-class five-for.

Keith Barker hangs his bat out to dry a little to a ball which moved away late and feathers an edge through to Michael Pepper behind the stumps.

You get a feeling the eventual chase won't be easy.

Huge wicket that was by the captain Sam Cook.

There's generous applause here for the highest scorer of the game so far with 91 but Beau Webster has just caressed a beautiful shot through the offside through extra cover and then with the very next ball a great reply from Sam Cook.

He's kept it pitched up, he's bowled it a little bit straighter and he's been castled.

It looked to me it just angled in but that is a cracking wicket by the captain of Essex in this game.

Following a sticky start at the crease, Lancashire's Josh Bohannon has settled well and is looking to take the attack to Gloucestershire.

He swats a wide one towards the vacant square leg boundary to move onto 13 not out.

Huge celeb appeal from Liam Guthrie as he thinks Max Holden has got a tickle on that down the legside through to wicketkeeper Lewis McManus.

Nothing doing.

Holden responds by belting the next ball square through the legside for four, and then runs three to go to 16 and reduce the deficit to just three.

James Rew plays a lovely reverse sweep into the ground for four more and moves onto 44 not out.

Moments later, there is a huge appeal, and Liam Dawson thinks Rew has edged behind to Ben Brown but umpire Middlebrook is completely unmoved.

Not out.

Kyle Abbott, around the wicket, beats the outside edge of James Rew's bat.

A good maiden over by the tall South African quicky.

He [Abell] and James Rew just having a chat no doubt about how to tackle Liam Dawson, whether to try and be a little bit more aggressive against him.

Back-to-back boundaries for Josh Bohannon.

The second is a back-foot punchy drive through the off side to give Will Williams something to think about.

Williams' immediate reply is a good one, and goes straight through Bohannon, but also goes over the top of off stump.

A quicker ball from Simon Harmer catches Keith Barker on the glove. It pops up but drops safe.

Sam Cook returns for another spell, replacing Zaman Akhter.

An unusually quiet over as Beau Webster - on 87 - plays out a maiden.

Eighteen overs still scheduled this evening.

Worked through the covers by Tom Abell for a single and it's 100 up for Somerset.

The following delivery from Liam Dawson is swept outside off-stump deliciously to the boundary by James Rew.

Edged from Keaton Jennings and the ball races away past gully region for Lancashire's first boundary of their second-innings.

A Sam Robson single brings up fifty for Middlesex for the loss of Josh de Caires.

Robson is finding his groove as he uppercuts Liam Guthrie past gully for four to go to 30.

The new bowler looks like he's still trying to find his rhythm, however.

It's all pretty much where we were pacing it as to how it might play out.

It's all eyes on tomorrow. Can Middlesex get any sort of position whatsoever that they might be able to defend a total if bowled out?

Big appeal from Hampshire spinner Liam Dawson but Tom Abell - who had been struck on he pads - had come a long way down the wicket.

Not out. Think it was a good call. Certainly the safe one.
