Yorkshire gave an emphatic demonstration of how they have become the dominant force in county cricket as they continued to overpower leaders Durham at Chester-le-Street.
Nine points behind with a game in hand at the outset, the reigning champions built an impregnable position on the back of Jonny Bairstow and Tim Bresnan sharing the highest seventh-wicket stand in county cricket history.
They put on an unbroken 366, beating the 345 shared by K S Ranjitsinhji and Billy Newham for Sussex against Essex at Leyton in 1902.
Yorkshire declared on 557-6 from 148 overs then reduced the leaders to 140-5 at the close, led by the excellence of Steve Patterson with 13-6-16-2.
The only two higher seventh-wicket stands in first-class cricket were recorded in India and Australia, the latter being 371 between Mitchell Marsh and Doncaster-born Sam Whiteman for Australia A against India A at Brisbane last year.
Bairstow’s unbeaten 219 beat his best of 205 against Nottinghamshire at Trent Bridge in 2011, while Bresnan’s 169 not out was 44 more than his 125 for England Lions against the Indians at Chelmsford in 2007.
The highest stand for any wicket against Durham was 359 between Surrey’s Mark Butcher and Ian Ward at the Oval in 2000.
Durham tried nine bowlers, including Keaton Jennings, whose first ball was cut for four to take Bairstow to 200 off 244 balls.
His fourth 50 came off 45 deliveries and he hit the only six of the innings with an overarm smash over square leg off a John Hastings bouncer.
Bairstow, who resumed on 102 and was watched by England selector James Whitaker, is averaging 106 this season with 636 runs.
Bresnan took his championship tally for the season to 501 at an average of 83.5.
Although they fell short of the fifth batting point, Yorkshire added 118 in the morning session.
Bresnan cut Jamie Harrison for his 16th four to complete his second championship hundred of the season off 149 balls.
Bresnan passed his previous best in the last over before lunch with two to deep mid-wicket off the occasional off-spin of Mark Stoneman.
A further 110 were added in 19 overs after lunch before the declaration left Durham with ten overs to bat before tea.
They sped to 37 after eight before Yorkshire turned to Adil Rashid and left-hander Jennings shaped to turn his second ball, a googly, to leg. It turned to take the edge on the way to Bresnan at slip.
In the next over Mark Stoneman, who had raced to 25, chopped an attempted cut off Steve Patterson into his stumps.
Paul Collingwood, pushing forward, was lbw to Patterson for nought on the resumption and Michael Richardson was dropped at slip by Alex Lees before he had scored.
The wicketkeeper made 31 before a Ryan Sidebottom swinger had him lbw then Gordon Muchall was yorked second ball by Bresnan.
That made it 81 for five, but Scott Borthwick and Pringle avoided further calamities for Durham in an unbroken stand of 59.
