Jonny Bairstow and Joe Root rewrote Yorkshire’s record books to give them control against Surrey after a shaky start to day two at Headingley.
Bairstow (198) and Root (190*) put on 372, a record fourth-wicket partnership for the county.
The England pair came together on 45-3 after Adam Lyth, Gary Ballance and Alex Lees were out in the first hour.
Bairstow, who survived a chance on 134, was caught at backward point as champions Yorkshire closed on 486-5.
- Bairstow batted for 4hrs 22mins, faced 231 balls and hit 24 fours
- Root batted for 5hrs and 51 mins, faced 221 balls and hit a six and 20 fours
- Average run-rate during their partnership: 5.5 per over
- They have batted together 32 times in first-class cricket, scoring 2,475 runs at an average of 77.34, with 11 hundreds and five fifties
- Yorkshire’s previous fourth-wicket record stand was 358 between Darren Lehmann and Michael Lumb against Durham in 2006
Having failed to win any of their opening three matches, Yorkshire made a poor start when Lyth was lbw to Ravi Rampaul for 13 in the fourth over of play.
Ballance did nothing to enhance his hopes of an England recall by playing on four overs later, while Lees jabbed at one from Tom Curran which he could have left and was caught behind.
Bairstow and Root were soon established, however, and launched a counter-attack which saw Yorkshire score 162 in 27 overs during the morning session.
Although the tempo slowed during the afternoon, the Bairstow’s century took only 96 balls and Root’s 110 as the Surrey attack toiled.
Arun Harinath could not hold a diving chance at mid-on offered by Bairstow, who fell just short of a double century when he was taken by Kumar Sangakkara off James Burke.
Captain Andrew Gale became Rampaul’s third victim before the close, with Root content to bide his time and press on for a double century on day three.
