Middlesex 44-5 (Robson 19)
Ryan Sidebottom's hopes of getting all 10 on the first morning against Middlesex at Lord's are ended by another of the Tykes' England pacemen Tim Bresnan, who strikes with the fifth ball of his first over after coming on at the Nursery End for Jack Brooks.
Neil Dexter is caught behind, after putting on 30 with opener Sam Robson.
Hampshire captain James Vince is living a charmed life in Taunton as the ball flies past his bat on more than one occasion and is lucky not to nick behind.
Michael Carberry is finding life at the crease far more easy as he sends Craig Overton for consecutive fours to move into the 40s.
Okay, the calculators have been out again at BBC Sport towers and we think we've got a definitive answer on what Yorkshire need to win the title...
If they bowl Middlesex out for less than 300 and Notts fail to reach 350, the White Rose county will be crowned champions.
In all reality Yorkshire could be celebrating at the end of today.
Hampshire 49-1
BBC Sport's Elizabeth Ammon at Taunton:
Hampshire 49-1 (Carberry 33)
Jimmy Adams falls in rather strange circumstances as Jamie Overton runs him out with a direct hit from deep extra cover, with Adams going for what looks like an easy third run.
A much needed breakthrough for Somerset.
Michael Carberry has found his scoring boots after a slow start with 24 of his 31 runs coming in boundaries, with Lewis Gregory feeling the brunt of his early morning aggression.
Hampshire are ticking along steadily as they look to escape relegation.
I mentioned earlier that Yorkshire needed six points to claim the title, but it appears they only need five, as even if they finish level on points with Middlesex they will claim the title with more wins.
It's all academic anyway, but just wanted to get the maths right!
Yorkshire's England contingent are certainly enjoying their side's good start.
Middlesex 14-4 (Robson 7)
Four wickets for Ryan Sidebottom and Yorkshire have one hand on the County Championship trophy.
Stevie Eskinazi edges the 37-year-old to Adam Lyth at second slip and Middlesex are in deep trouble.
Yorkshire will be batting before lunch at this rate.
The bowlers are certainly making the most of the cloudy overhead conditions.
At Trent Bridge, Notts are now 7-3 against Durham , with Graham Onions picking up a couple of wickets.
Kent have also lost Daniel Bell-Drummond early in their match against Glamorgan - they're 23-1.
No such alarms at Taunton as Hampshire tentatively ease themselves into the match.
Just one run has come off the bat so far with eight leg byes having been conceded between opening bowling pair Craig Overton and Lewis Gregory.
What a baptism of fire this is for Middlesex debutant Stevie Eskinazi.
The 21-year-old is now at the crease after those three wickets in the first over.
It's going to be a tough test, that's for sure.
Middlesex 0-3 (Robson 0)
Three have gone in the first over! I can't quite believe this.
Ryan Sidebottom bowls Dawid Malan first ball.
Incredible.
Middlesex 0-2 (Robson 0)

It's Ryan Sidebottom again - Nick Compton edges him behind.
0-2.
Middlesex 0-1 (Robson 0)
Well that didn't take long!
Ryan Sidebottom has removed Paul Stirling, lbw, with just the third ball of the morning at a very overcast Lord's.
That's his 700th wicket in first-class cricket as well.
What a start for Yorkshire.
Nottinghamshire 1-1 v Durham
We have our first wicket of the day ladies and gentlemen.
And it's that man Chris Rushworth again!
Jake Libby is the man to go, caught by Gordon Muchall.
Middlesex v Yorkshire (10:30 BST)
I said it would be a short delay...well the teams are on their way to the middle.
Middlesex v Yorkshire (10:30 BST)
It looks like we're in for a short delay at Lord's because the light isn't quite good enough to start.
Don't think it'll be too long before we get under way though.
