It's been a hectic day - and that's all from us.
Take a bow Dawid Malan, Jack Burnham, Mark Pettini, Jake Libby, David Lloyd, Graham Wagg and James Hildreth and Brett D'Oliveira, who all made County Championship centuries.
On top of that, Northamptonshire's Rory Kleinveldt hit 24 off one over in his innings of 97, James Anderson took three wickets in one over for Lancashire and Worcestershire's Joe Leach took four wickets in four overs, including that of Alastair Cook.
But pride of place must go to 19-year-old Burnham, who became the third youngest player in Durham history to score a Championship hundred.
We'll be back tomorrow for the final day of action in the current round of matches. Play starts at 11:00 BST.
