So that's where we'll draw stumps ourselves at the end of the first day.
A few impressive innings from across those nine fixtures.
Hats off to Gary Ballance though, who will resume on 120 not out tomorrow for Yorkshire against Hampshire.
You can read how he performed as well as all the other day's reports on the counties page of the BBC Sport website.
We'll be back for day two from 10:45 BST on Friday. Thanks for being with us.
