After more than 100 minutes of sweat and toil, a great end to the session for Sussex.

The wickets of Wayne Madsen and David Lloyd have changed the mood as the Division Two leaders now only need six more Derbyshire wickets.

They are still 109 runs adrift and much of their hopes rest with Harry Came who is 72 not out from 248 balls.

... but I am honestly not sure if either team will be able to eat anything,..

This one has become very interesting indeed in the past half-hour, with three wickets falling in just over six overs.

109 more runs required after lunch for the hosts to pick up a win which would keep them in the title chase. However only six wickets with which to do it.

In theory all four results remain possible on the final afternoon of day four.

Would anyone have it any other way?

Jack Leach rattles off a maiden to enable Somerset to squeeze in one more over before the interval and Bas de Leede takes the opportunity to score his first boundary off Archie Vaughan.

De Leede has seven, with Ashton Turner on 11 at the other end and it looks like an extremely uphill struggle for Durham to stave off defeat here, unless the weather intervenes.

A super morning for Notts who have completely stalled Surrey's hopes of pushing for victory.

Only 90 runs added off 31 overs with three wickets lost.

Remarkably, spin duo Liam Patterson-White and Farhan Ahmed have bowled all 38 overs so far in this innings.

Surrey lead by 224 runs with 72 overs left in this game. Surely even they can't force a win in this one.

Adam Lyth and Finlay Bean add 14 to the Yorkshire lead in the four overs before lunch and that puts the home side 93 ahead overall.

That ends a comparatively wicket-laden session, with Middlesex's last five all falling after just 11 had gone down across the previous three days.

Still hard to see anything bar a draw in this one, but you never know.

Ajinkya Rahane and Peter Handscomb have made their task vastly more difficult with a stand of 183 but Glamorgan's hopes of victory are still alive, just.

Rahane departed for 102 but Peter Handscomb remains unbeaten on 94. Leicestershire trail by 28 and have six wickets in hand.

A couple more after lunch and things might get interesting.

Keep an eye on the skies this afternoon too, you can bet Leicestershire will be...

Notts 405 v Surrey 525 & 100-4

Rory Burns runs a single off Liam Patterson-White and that is Surrey's 100 up.

But this is the 37th over, so we are under three runs an over.

Can we mention the D word now?

It'll be interesting to see how Yorkshire approach this second innings. Even though the pitch has offered the bowlers more assistance this morning, you can't imagine they'll want to risk setting Middlesex a target in the final session.

With that said, it's a brisk start from Adam Lyth second time around as he cuts Toby Roland-Jones for two boundaries in the opening over.

Farhan Ahmed sends a beauty past Rory Burns from round the wicket.

He has 1-42 from 17 overs in this innings, bowling unchanged from the start.

The 16-year-old is doing a superb job in keeping the brakes on this Surrey second knock.

Bas de Leede is finally off the mark, nudging Jack Leach away for two behind square, although runs are probably not relevant to the match situation now with Durham needing another 340.

It's all about survival and, while Durham are six down, bear in mind that they still have first-innings centurion Brydon Carse and Ben Raine to come in at nine and 10 respectively.

A beautifully-timed punch down the track from Jordan Cox off Logan van Beek beats the dive of Joe Leach at mid-on and races away to the rope.

120 more required for Essex.

How Worcestershire would love a third wicket before lunch.

Sussex 607-8 dec v Derbyshire 290 & 202-2

A lousy long hop from Fynn Hudson-Prentice and Wayne Madsen thunders it through the covers for the four it deserves.

That sees the 200 come up for the visitors, who still trail by 115 runs.

Balls like that are not what Sussex need with the new cherry.

Glamorgan 550-9 dec v Leicestershire 251 & 253-3

His first for Leicestershire and his 40th in first class cricket. The 36-year-old has 85 caps under his belt for India and is showing all that experience here.

He brings up three figures from 178 balls with consecutive cuts for four off Kiran Carlson.

Rahane was dropped twice in the 30s by Mason Crane off his own bowling yesterday, remember.

The deficit is under 50.

Sam Northeast is digging into his bag of tricks and has tossed the ball to Kiran Carlson to turn his arm over as the hosts seek to break this partnership which is edging towards 200.

The 26-year-old has 34 first class wickets in 90 matches at 57... although did pick up 5-28 once. What Glamorgan would give for another of those this afternoon.

A mammoth bowling stint by Dom Bess finally comes to an end as he claims his seventh wicket!

The Yorkshire spinner's final figures are 7-179 from 70.4 overs as Noah Cornwell swings him away on the off side and Jordan Thompson, back-pedalling, does extremely well to complete the catch.

Cornwell's maiden Championship innings ends without a run and Middlesex are finally bowled out for a deficit of 79.
