Yorkshire seamer Jack Brooks took four wickets in 15 balls to finish with figures of 4-76 on his Championship debut for the White Rose.
This represented a recovery for the former Northants man, who had 0-60 off 9.4 overs at one stage.
The seamer who held the attack together was Ryan Sidebottom, who had last-man Monty Panesar lbw for one to finish with 4-72 off 21.5 overs.
In Yorkshire's second innings, Stuart Magoffin removed Alex Lees, caught by Chris Jordan at slip for a single before bad light stopped play with Yorkshire on 27-1.
