Cook 165, ten Doeschate 19
Just a single to Alastair Cook off Jack Leach's 22nd over as the shadows lengthen at Lord's.
Right, will Somerset take the new ball?
Cook 164, ten Doeschate 19
Streaky from Ryan ten Doeschate!
The former Essex captain edges the final delivery of Tom Lammonby's over to the fence.
One over to go until the new ball is available.
Cook 163, ten Doeschate 15
Alastair Cook slices Jack Leach behind point and they run three to take Essex past 250. Still got the legs after six hours at the crease has the 35-year-old.
Ryan ten Doeschate is five years his senior, but a bit fresher!
Cook 160, ten Doeschate 15
Another tidy over from medium-pacer Tom Lammonby - a second maiden in a row in fact.
These two experienced Essex heads know if they're still there at stumps, they may have one hand on the trophy.
Cook 160, ten Doeschate 15
Alastair Cook moves to 160 with a nice clip for two off Jack Leach.
A couple of singles before that as the game continues to drift along with the new ball on the horizon.

After that little furry of three wickets Somerset haven't been able to grab another one but they have managed to stall the run rate.
Jack Leach has bowled 19 overs now and he hasn't got a wicket but he's been on target and kept things quite.
Cook 157, ten Doeschate 14
A second maiden in a row, this time from the returning Tom Lammonby.
The new ball is due in five overs... anyone remember what happened yesterday around this time?
Cook 157, ten Doeschate 14
Alastair Cook is happy to block out Jack Leach's latest over of spin.
14 overs remain on day three. Can Essex creep into a lead? They need another 58.
Cook 157, ten Doeschate 14
The buoyancy Somerset had just after tea when they took those three quick wickets is beginning to fade a little.
Josh Davey slings one down onto Ryan ten Doeschate's pads and he flicks it fine for four.
Davey goes straight again, ten Doeshcate misses, but it was sliding down leg.
Essex trail by 57.

If you're still unsure which way the pendulum might swing in this final as we enter the last hour of this third day, let me give you two things to ponder.
1) Essex's highest total in this competition so far this season is 298.
2) Somerset slumped from 266-5 to 301 all out when Essex took the second new ball in the evening session yesterday.
I think the expression is "delicately poised".
Cook 156, ten Doeschate 10
Jack Leach rattles through his 18th over as three singles come off it. Still wicketless is poor Jack. I must say I'm missing his big grin - no doubt a breakthrough would bring that!
Cook 154, ten Doeschate 9
Maiden from Josh Davey. Somerset need a few more of those just to put a bit of pressure back on Essex.
Cook 154, ten Doeschate 9
Boundary number 25 for Cooky.
Jack Leach strays outside off stump and Alastair Cook slaps him to the rope - the umpteenth time he's played that shot in this innings.

It's remarkable hunger from Cook to achieve what he achieved in the game, he still turns up for Essex and still leads from the front
Essex 231-4
Alastair Cook punches Jack Leach straight and has to sprint to make his ground. A direct hit and it may have been close.
But it takes him to 150 off 251 balls with 24 fours. A magnificent knock and there may well be more to come.
Cook 149, ten Doeschate 8
Alastair Cook squeezes out a single off Josh Davey to move to 149.
I wonder if he'll see this as one of his finest innings once it's been and gone? Some of his strokeplay through the off side has been outstanding.
Cook 148, ten Doeschate 8
Runs are beginning to come again for Essex. Ryan ten Doeschate wristily guides Jack Leach past slip and down to the boundary.
They're 73 runs away from what could be a crucial and match-winning first-innings lead.
Cook 148, ten Doeschate 4
Gorgeous shot from Alastair Cook. Josh Davey overpitches and Cook strokes him through the covers to move to 148.
Next ball Cook is plonked on the pad on the front foot - massive appeal from the bowler and slip cordon but it's turned down. He may have got outside the line.
Cook 143, ten Doeschate 3
Ryan ten Doeschate pushes forward to Jack Leach and is struck on the pad, the spinner appeals but the umpire shakes his head.
Two off the over. Another wicket for Somerset would make things hugely interesting.
Cook 143, ten Doeschate 1
Ryan ten Doeschate squeezes one off his pads, just about, to get off the mark.
A couple of singles off Lewis Gregory's 16th over. The England seamer has 3-51.
