It's a different contest at Lord's now that the overcast morning conditions have disappeared. 

Yorkshire's openers Adam Lyth and Alex Lees have looked at ease inside the first six overs.

Lyth's four scoring shots have so far all been boundaries.

But, in the Yorkshire dressing room, and certainly in the commentary box, most eyes and ears are trained on Trent Bridge where Nottinghamshire, the only team who can now stop the Tykes retaining their title, are rallying on 144-7.

Plenty of resilience being shown by Notts batsmen Steven Mullaney and Luke Wood against Durham.

The pair have put on 61 for the eighth wicket so far.

Nottinghamshire still odds on to be bowled out for less than 350 though which will hand Yorkshire the title.

No hat-trick for Jim Allenby as Ryan McLaren keeps him at bay, but the Australian all-rounder has swung this match in the space of a couple of minutes.

England discard Adam Lyth strikes two boundaries in the first over off Tim Murtagh as batting at Lord's is suddenly made to look a lot easier.

Certainly a happier return to Lord's for Lyth than on his last visit in mid-July when he was twice caught behind cheaply off Mitchell Starc in the second Ashes Test, the first of them a second-ball duck.

Things are a little bit less chaotic in the second division, where Kent have reached 182-2 at Glamorgan  with Rob Key (81 not out) closing in on a century.

Essex teenager Dan Lawrence has struck his first half-century since his 161 against Surrey in April.

They are 128-2 against Derbyshire .

Hampshire are edging towards their first bonus point of the innings as Will Smith and Liam Dawson look to rebuild for the visitors once again after the loss of James Vince.

Somerset, who were five points ahead of Hampshire at the start of play, have already picked up their first bonus point after taking three wickets.

Ryan Sidebottom's return of 5-18 in 12 overs at Lord's was his third 'five for' of the season, taking his campaign haul to 39 Championship wickets in only his ninth match. Not a bad effort for a 37-year-old whose season was curtailed by an early season calf injury which caused him to miss seven matches.

He also went past 700 career first-class wickets.

Fellow England paceman Tim Bresnan weighed in with 4-30, but it was Sidebottom's triple-wicket maiden at the home of cricket to get this game off to such an amazing start which will most long be remembered.

Only a matter of time now, surely.

Steven Mullaney and Luke Wood are battling hard for Notts taking them to 115-7.

They've put on 42 in quick time.

Middlesex bring the 100 uppublished at 13:39

The crowd are on their feet (well one man at least) as the home side reach three figures.

Tim Murtagh was the man who took them past the 100-mark, with a three off Ryan Sidebottom, followed by a boundary from James Harris.

Now on 106-9, Middlesex are just 244 away from the four batting bonus points they need to stay in the title race!    

There's certainly some pretty happy Yorkshire fans at the moment...

Just 11 runs and the vital wicket of James Vince in the first five overs after lunch.

The game is delicately balanced in the match some are terming the '32-point relegation decider.'
