An absolute shellacking for the Pears away to Yorkshire, going down by 504 runs, a record Yorkshire win for weight of runs and a record defeat on runs for Worcestershire to boot, breaking a 116-year-old record by more than 100 runs.
Dom Bess scored a second innings 107, his first in county cricket, while there were five wickets in the match each for Ben Coad and George Hill.
In Division Two Kent boast an impressive win of their own, chasing down 316 v Middlesex with eight wickets and a day to spare at Canterbury.
The chase was managed with some style by Ben Compton (124*) and Tawanda Muyeye (125*) after Zafar Gohar removed Zak Crawley (58) and Daniel Bell-Drummond in two balls.
Where will we see our next result?
Perhaps at Hove where Somerset are 125-4, still 470 short of a hefty target, boosted by tons from Tom Haines and John Simpson.
Surrey have set Hampshire a hefty target of 377 and will be confident going into day four with Hampshire 342 short on 35-3, with two night watchmen gone in two balls.
Early days for the Bears in their pursuit of 339 to beat Durham at the Riverside. The away team are 12-0.
Notts are making a good game of it at Trent Bridge v Essex but how many will be enough? 213 ahead and five wickets in hand at stumps with Jack Haynes unbeaten on 49.
Northants still have a lot of work to do after forcing Lancashire to follow on at Old Trafford in Division Two, but were boosted by the second innings scalp of Keaton Jennings just before the close.
Leicestershire are building a big lead at home to Derbyshire, now 382 ahead, while Glamorgan are battling hard 55 in arrears v Gloucestershire, following-on at Bristol with all 10 wickets in hand.

Hampshire 31-3, target 377 to beat Surrey
Rory Burns tosses the ball to umpire Martin Saggers and the light has finally won...
That will also be stumps.
A torrid spell for Hampshire who have lost opener Mark Stoneman to Kemar Roach and then nightwatchers Brad Wheal and Sonny Baker to a fired-up Jordan Clark.
Earlier Dom Sibley made his second century of the game, making 105 with Jamie Smith adding 84 as the hosts made Hampshire toil in the field before a late flurry from Sonny Baker who claimed 5-80 - his first county championship haul.
It's been Surrey's day, will Monday be theirs too?
Glamorgan 385 & 106-0 f/o (trail by 55 runs) v Glocs 546
Just like at Christmas, the great escape is definitely on with Glamorgan negotiating 31 overs to the close of day three without losing a wicket.
Zain ul-Hassan (51) and Eddie Byrom (49) are the not out batsmen who did a fine job tonight and will return in the morning with the first target being the 55 to reach parity and make Glocs bat again.
The fact they were pretty comfortable throughout this evening session would suggest it is the hosts who may have the harder job taking 10 wickets.

First ball.
Jordan Clark thunders one in which almost cuts Sonny Baker in half, the ball comes off the shoulder of the bat as he takes evasive action and loops to Ollie Pope at second slip.
JORDAN CLARK IS ON A HAT-TRICK.
Nick Gubbins, not a nightwatcher, is in for it...
... and smothers one which was destined for off-stump.

Warwickshire 12-0, target 339 to beat Durham
Rob Yates and Alex Davies (10*) negotiate the tricky four-over spell before stumps without undue alarm.
They'll come back tomorrow with the prospect of a 3.5-an-over chase - if they get a full 96 overs in, with all 10 wickets in hand.
Quite a day with Ben Raine's lovely 81 helping the hosts post such a testing target while Michael Booth's four-over blast of 4-10 in the early afternoon kept things in the balance for a long while.
Let's hope for decent weather tomorrow, this game deserves a winner.
Sussex finish day three not just in the driving seat, but with the radio on full blast, window down and honking the horn every few hundred yards.
A target of 595 looks a world away from Somerset's batting line up with four of their men already back in the hutch.
Tom Abell, on 60 not out and James Rew on an unbeaten 19, have much of the responsibility on their shoulders and while they are there Somerset will continue to believe they can bat out the overs.
But one wicket should see Sussex sense blood.
Sean Hunt has been not only the pick of the bowlers taking the last five wickets to fall in the first innings but he has backed it up with all four of those to fall in Somerset's chase.

Nathan Fernandes bowls to Ben Compton.
He pushes the second ball leg side for two. Level!
Worked away on side and Kent win!
Great start to the chase from Zak Crawley with a brisk 50.
Zafar Gohar hit back for Middlesex with two wickets in two balls, dispatching Crawley and Kent skipper Daniel Bell-Drummond.
Compton and Muyeye put on an unbroken 225 to soak up the pressure and transfer it back on to Middlesex and they walk off to deserved applause in the fading Kent sunshine.
A desperately close draw at home to Lancashire at Lord's in the season opener and now a thumping loss here v Kent for Middlesex.

Notts 347 & 233-5 (lead by 213) v Essex 367
And that is that. A finely poised day with both sides losing five wickets and with the match very much in the balance.
Notts have battled pretty well since going in again with Haseeb Hameed (92) and Ben Slater (67) contributing well.
With Kyle Verreynne gone, much will rest on the shoulders of Jack Haynes, who finishes unbeaten on 49.
Verreynne's dismissal will divide opinion given he could have been saved for the morning but either way, the decision to send him out instead of a nightwatchman will probably not decide the game.
For Essex, Simon Harmer has made two decent breakthroughs without really suggesting this is a spinner's wicket, but the visitors will be hopeful that a decent first session tomorrow will give them a good chance of knocking off a sub-300 target.
