Resuming at 36 without loss, James Wharton was bowled in the second over of the day without adding to his score.
Jonny Tattersall joined Will Fraine and they added 25 before Fraine was also bowled for 29. Matthew Revis went in similar fashion shortly after to reduce Yorkshire to 74-3.
A hundred was reached just before Tattersall was adjudged lbw for 24 and Ben Birkhead was caught behind for five. At lunch, the White Rose were 113-5.
Harry Duke made 27 and at 128-6 we were still glancing at the follow-on figure, however Mat Pillans struck 44 from 41 balls with five fours and two sixes. Pillans was caught at long-on leaving Yorkshire at 193-7, but from here the home side subsided to 207 all-out, trailing by 92.
The Derbyshire second innings followed a similar vein to their first in so far as runs came quickly. The visitors had reached 47 in the 13th over before losing their first wicket – McGladdery caught behind.
When play finished early due to bad light, Derbyshire had taken their score to 113-2, a lead of 205.
