George Hill took five wickets for Yorkshire
It's been a tough day for batting at a number of grounds with five teams bowled out inside the opening day - four of them in Division One, including leaders Nottinghamshire.
They only mustered 228 all out but a couple of Yorkshire wickets before the close will have made them feel a lot better - second-placed Surrey, meanwhile, ran through Essex for 217.
Batters fared better in Division Two with Derbyshire's Caleb Jewell, Saif Zaib of Northamptonshire and Glamorgan pair Sam Northeast and Kiran Carlson hitting centuries.
Join us again tomorrow from 10:30 for full coverage of the second day's play.
