We're back under way after lunch and Notts have already lost another wicket to leave them 73-7.

Graham Onions has his third for Durham , trapping Brett Hutton lbw.

Yorkshire could be champions in the next half hour.

By our maths Jim, if Yorkshire bowl out Middlesex for less than 300 and Notts are out for under 350, Yorkshire will be champions.

If that doesn't happen, Yorkshire need five points. They've already got two!

A decent morning so far for Essex with Dan Lawrence in sight of a half-century.

The teenager is 43 not out.

Mark Footitt has picked up the only wicket to fall when he bowled Nick Browne.

BBC Radio Kent's Ben Watts in Cardiff:

"The wicket of Sean Dickson, chasing a wide one from David Lloyd in the final over before lunch, was a real bonus for Glamorgan in a morning otherwise dominated by Kent.

"After Daniel Bell-Drummond was bowled by Michael Hogan early on, Rob Key (61*) and Dickson (59) amassed a partnership of 122 at an impressive rate of more than four an over.

"Early signs suggest it was a good toss to win for the visitors to win."

BBC Radio Nottingham's Dave Bracegirdle at Trent Bridge:

"Nottinghamshire struggled against the new ball prowess of Chris Rushworth and Graham Onions on the first morning against Durham.

"Both strike bowlers picked up two wickets and there was no respite for the home side at the other end, as Jamie Harrison and Barry McCarthy, a 22-year old debutant, also struck to vindicate Paul Collingwood’s decision to put the hosts in.

Rushworth, Division One's top wicket taker, removed Jake Libby in the first over of the day and, when Brendan Taylor drove to point, beaten One-Day Cup semi-finalists Notts were reduced to 1-2 for the second time this week.

Steven Mullaney, who replaced Libby at the crease, batted throughout the remainder of the session to move on to 24 at the interval. But he saw four of his colleagues nick the swinging ball through to wicketkeeper Michael Richardson, the last of them captain Chris Read off the last ball before lunch."

Good toss to win as reigning champions Yorkshire take seven Middlesex wickets in the morning session, to move within reach of their second successive title.  

BBC London 94.9's Kevin Hand at Lord's:

"The toss was always crucial given the 10.30 start times in September, a greenish tinge to the pitch and leaden skies over the capital.  

"With only five points required to seal their crown at the start of play, Ryan Sidebottom got the visitors off to the perfect start, taking three wickets in the opening over.

"He added a fourth before Tim Bresnan nipped in with two, then spinner James Middlebrook struck in the final over before lunch."

It's a fifth first-class half-century of the season for James Vince, despite a scratchy start to his innings. The Hampshire captain began to start to find the middle of the bat and hit nine fours on his way to 50.

In the battle to avoid relegation between these two sides, Hampshire head to lunch probably the happier of the two teams.

BBC Wales Sport's Nick Webb at Cardiff:

"Kent made a positive start after winning the toss with a century stand between club captain Rob Key (61 not out) and South African newcomer Sean Dickson.

"Both played attacking shots after Michael Hogan removed Daniel Bell-Drummond in the second over, but Dickson fell to David Lloyd for 59 in the over before lunch."

Middlesex wicketkeeper John Simpson has clearly decided that the best form of survival against county champions elect Yorkshire is to match fire with fire. 

He has so far struck five boundaries in 15 balls on the approach the lunch interval to steer his side to within reach of three figures.

Yorkshire's morning by far.

Jamie Harrison has got in on the act at Trent Bridge, removing Chris Read to leave Notts 70-6.

Don't forget, if Notts are bowled out for less than 350 and Middlesex fail to reach 300, Yorkshire will be champions.

Meanwhile, Essex are 80-1 against Derbyshire and Rob Key and Sean Dickson both have half-centuries for Kent who are 120-1 against Glamorgan.

The Yorkshire fans are already celebrating!

The 100 is up for Hampshire as James Vince drives Jamie Overton for a couple down the ground.

It has been a pretty chanceless session by the visitors, apart from the loss of Jimmy Adams - which was more down to a superb throw from Jamie Overton as opposed to batsman error.

Chris Rushworth has another for Durham at Trent Bridge to leave Nottinghamshire 37-5.

Samit Patel is the man to go.

Meanwhile, Former England opener Marcus Trescothick has signed a new one-year contract with Somerset.

The 39-year-old was a member of the 2005 Ashes-winning side before his international career was cut short by a stress-related illness.

Somerset director of cricket Matthew Maynard said: "Marcus is the absolute model professional. His experience and knowledge are second to none.

Spinners Max Waller and Jack Leach and seam bowler Josh Davey have agreed new two-year deals with the county.

A rare ripple of morning applause for Middlesex as their 50 comes up in the 16th over of the day, as James Franklin gets off the mark with a boundary off Steve Patterson.

It has been a fine morning for Michael Carberry as he reaches his half-century by sending Craig Overton to the boundary for the 10th four of his innings.

Put the champagne on ice fellas, as Nottinghamshire are also in big trouble at Trent Bridge.

Durham debutant Barry McCarthy has just picked up his first wicket, removing Riki Wessels, to leave Notts 37-4.

In Division Two, Kent are 62-1 against Glamorgan  and Essex have just lost their first wicket after Nick Browne was bowled by  Derbyshire paceman Mark Footitt. They're 48-1.
