Sam Northeast takes a couple off and plays out the rest of Ben Mike's third over.

It’s been slow going at Leicester as Glamorgan have added 72 runs this morning for the loss of Eddie Byrom and Marnus Labuschagne.

The visitors won’t mind the stately pace as they look to take any drama out of the day.

They move their lead up to 128.

We have 66 overs left in the day.

They keep trying to get out there, but no luck so far.

The latest provisional start time is 13:30 BST, with 67 overs scheduled.

Ricardo Vasconcelos takes a two off the first ball of George Hill's second over and then plays out five dots to reach lunch. Job done.

They've chipped 13 runs off thir tantalising target of 325, set by Yorkshire's adventurous declaration 20 minutes before lunch.

Shan Masood chalked up his second Championship century of the season and moved to 131 when he decided to call time.

We could be in for an absolute belter here this afternoon.

This one is heading for a draw but there has been some enterprising batting this morning by Middlesex, who have added 105 for the loss of two wickets.

Nathan Fernandes and Jack Davies extended their partnership to 119 before Davies fell to Jack Carson for 68.

Fernandes followed, caught in the deep for 91, and Middlesex are 46 in arrears with two sessions to go.

Simon Harmer is actually fielding on his knees at second slip as Joe Denly plays out a maiden from Matt Critchley to end the morning session at the Spitfire Ground.

The follow-on having been enforced before the start of play, Kent have lost half of their wickets - assuming Wes Agar will bat today - with Harmer picking up 3-20 from nine overs.

Kent need another 133 to avoid an innings defeat. Joe Denly is 11 not out and Joey Evison has four.

A rare wide half-volley from Simon Harmer and Joey Evison does not miss out on that one as he cover drives for four.

Matt Critchley will bowl what is probably the last over before lunch.

Hopes fade of any kind of result at Worcester as another inspection is announced while the players tuck into their early lunch.

The umpires will have another peek at the wicket at 1.30pm.

Tidy stuff from George Hill as he opens up with a maiden to Emilio Gay.

Two more from Ricardo Vasconcelos off Vishwa Fernando and then a single brings Gay back on strike.

Fernando invites Gay to drive and he does - uppishly and not totally convincingly for two.

An awkward 15-minute spell before lunch awaits openers Ricardo Vasconcelos and Emilio Gay as Northants begin a chase of 326 off 71 overs.

Vishwa Fernando has three slips as he begins Yorkshire's pursuit of 10 wickets.

Vasconcelos plays out four dots and then picks up two.

Fernando gets some swing with his final ball but overpitches and Vasconcelos plays it past the right of the cover fielder for the first boundary of the second innings.

Half-way down from Tom Clark and Nathan Fernandes square cuts for four. A poor ball which got what it deserved. Fernandes moves into the 90s.

Ajeet Singh-Dale has already lasted longer than MDL, Matt Taylor and Ed Middleton before him, he guides five-fer man Zak Chappell through the vacant gully for four to reach nine off 15.

Beau Webster continues to motor to 67 off 67 now.

Northamptonshire will need 326 to win.

They are going to have a nasty little 15 minute session before lunch but a very well done Shan Masood, a super innings from him, he's really stepped up the gears in this morning's play.

Joe Denly sweeps Simon Harmer for four.

He then comes down the pitch and let's it strike him on the pad.

Harmer appeals but the gap between pad and stumps saves him.

It's the first time Daniel Bell-Drummond hasn't past 50 in one of the innings of a match this season.

It feels like this day four wicket is finally starting to misbehave having been flat and slow and very much in favour of the batters for the majority of the game.

Simon Harmer and Matt Critchley are starting to find some joy.

Ajeet Singh-Dale plays his trademark clip for three off Zak Chappell through mid-wicket to get off the mark and earn the home side's 500.

He was falling over as he played it wristily, but nicely timed, and maybe Webster may trust him more after that shot?

The interruption was brief and the sun has reappeared at Northampton.

Rob Keogh has four balls left to complete his 11th over.

Shan Masood shows immediate intent, shovelling the first ball over mid on and takes a couple.

A wide follows before th Yorkshire captain goes big, pulling a Keogh ball outside off stump over the legside for a big maximum.

He takes a couple and then two more from the last ball. Seventeen from the over.

And that will do. Yorkshire have declared 325 runs ahead. Game on
