We've known the outcome of this for several days.
Yorkshire will know they'll have a lot to do to not end up in a relegation battle at the back end of the season.

It could be a tricky chase for them.

Ben Slater enjoys playing Durham. He's just reached 50 for the second time in this game and now has nine half centuries against them, plus a double hundred.
The latest came in 69 balls and included 9x4s. He made 52 in the first innings and is on the same score now.
Two wickets have fallen today. Nightwatchman Rob Lord was caught by Ben McKinney at first slip on 15, off the bowling of James Minto.
Freddie McCann then survived two massive shouts for caught behind off Ben Raine. The bowler looked stunned when Peter Hartley refused to give either.
But Brydon Carse then bowled McCann for six anyway, so his luck didn't last for long.
Bairstow b Patel 77 (Surrey 512 v Yorkshire 255 & 216-8 - trail by 41 runs)
That's the big, big wicket for Surrey!
Ryan Patel hasn't bowled for about a year but now he's got none other than Jonny Bairstow!
Clean bowled and Yorkshire's key man is gone for 77.
Just two more wickets needed now for the hosts to complete the victory.
