Here's something to get cricket ground staff at all levels salivating.

That small partnership will have calmed down the Essex dressing room again.

Alastair Cook the immovable object again is looking very assured at the crease.

Essex will feel like slight favourites but Somerset have done well picking up those two wickets.

Somerset will still feel if they can pick up three hopefully four wickets from their point of view in the next session then that would really make an interesting final session.

Still hard to call which way this one's going to go.

Potentially four results on the table still with two sessions to go.

You sense a couple of quick wickets after lunch puts Somerset ahead, 30 more runs without losing one makes Essex favourites to chase it.

Of course, a draw also sees them take the trophy after the first-innings lead of 36.

Just to let you know, if the match finishes as a tie - the trophy will be shared. What a twist that would be!

61 overs remain today, although it's still really gloomy at Lord's. I wouldn't bank on Somerset having more than 50 to try and bowl out Essex.

As has been the case so often over the past 15 or so years, the wicket of Alastair Cook is key.

Alastair Cook safely negotiates Josh Davey's final over before the interval.

Cook and Dan Lawrence have done well to see out a tricky spell under floodlights after Somerset claimed two wickets in two overs.

Essex are still favourites for the title, but Somerset have a sniff.

Dan Lawrence is saved by an inside edge otherwise a leg-before shout from Lewis Gregory looked plumb.

The right-hander then guides the seamer down to the third-man fence.

Final over before lunch coming up...

At Edgbaston, the runs are continuing to flow for Southern Vipers against Northern Diamonds in the Rachael Heyhoe-Flint.

But Maia Bouchier has just departed for 28 after making a 50 partnership with Georgia Adams (73 not out) for the second wicket.

It's a 50-over match just to remind you.

Couple of overs to go until lunch, key period on this last day.

Five come off Josh Davey's sixth over - a three down to third man to Dan Lawrence and a couple behind point to Alastair Cook who moves on to 29.

Big appeal for lbw against Dan Lawrence from Lewis Gregory but it's turned down. A quick single comes off the over.

Just a single to Dan Lawrence off Josh Davey's over.

15 minutes to go until lunch. If Essex can see it out without any further damage, they'll remain favourites for the title.

Don't forget, a draw gives them the trophy.

Wild scenes of celebration among the media - the Compton Stand scoreboard is back working again!

But, you'll also notice from the picture above just how gloomy it is now as well with the floodlights in full effect.

This final continues to be delicately poised.

This is a good period for Somerset, Gregory is running in well and is bowling some good deliveries.

Essex need to do well to get through this stage.

Peter Walker: Dan Lawrence reminds me somewhat of a young Keith Fletcher. And you have to be very old to be able to make that comparison.

There's probably quite a lot in that as Fletcher has done a lot coaching over the years with Essex's academy players.

Alastair Cook is almost run out!

Dan Lawrence prods one to square leg, calls Cook through, the fielder swoops and just misses the stumps. Cook might have been short.

He follows it up by clipping a Lewis Gregory no-ball off his pads to the rope. Another no-ball and then a swivel pull to the boundary.

13 off the over.

Josh Davey continues to cause Alastair Cook problems from around the wicket as he seams one past the left-hander's outside edge.

Another maiden. 67 overs remain.

Lewis Gregory gets through a maiden as the floodlights continue to beam down brightly at Lord's.

Meanwhile at Edgbaston, there's been a breakthrough for the bowlers.

Northern Diamonds have a wicket in the Rachael Heyhoe-Flint final after winning the toss and choosing to bowl.

Southern Vipers opener Ella McCaughan has fallen for 35 after making a 100 partnership with the first wicket alongside Georgia Adams (57 not out).

You can follow that match on the link below.

Howzaaaaaaat?

Craig Overton hits Alastair Cook on the front pad but umpire Rob Bailey shakes his head.

Three off the over and the target is down to 200.

Lights on. Bowlers and fielders with their tails up. A trophy to be won.

This is engrossing stuff without doubt.

Such a shame there isn't a crowd allowed in to see it unfold as I'm sure they would all be on the edge of their seats.

The one man Somerset really want is Alastair Cook.

The left-hander cuts Lewis Gregory through point for four and then sees out the rest of the over, although Gregory beats him with the last ball.
