A tireless Day Three bowling effort from Nottinghamshire enabled the Green and Golds to set up a final-day run chase for a win that could see them contest the Bob Willis Trophy at Lord’s next week.
Yorkshire made 396 following on, of which opener Adam Lyth hit 153, which left Notts chasing 174 to win, and the home side closed on 42 for one, needing 132 more.
A victory here would give them the chance to take on Lancashire in the season finale at Lord’s by finishing second if Warwickshire fail to beat Somerset.
Lyth batted for eight and a quarter hours and hit 20 fours, leaving the field to generous applause from the home crowd after finally being dismissed by teenage all-rounder Joey Evison.
Three down overnight, the visitors turned a deficit of 54 into a lead of 29 by lunch with only one further wicket lost, Will Fraine falling leg before to Brett Hutton.
Luke Fletcher, the leading wicket-taker in the Championship with 66 scalps, was hit for four boundaries in the same over by Harry Brook, who also took three in one Hutton over as he and Lyth added 79 for the fifth wicket.
Dane Paterson - easily the pick of the home bowlers with three for 39 - produced a good ball to have Brook taken at first slip for 42 just after lunch, at which point Yorkshire were effectively 38 for five.
However, Lyth found another ally in Jordan Thompson, with whom he added 74 before his fellow left-hander edged Steven Mullaney to second slip.
Taking tea at 341 for six, Yorkshire were 118 in front, before Lyth’s innings ended three overs into the last session, when a beauty from 19-year-old Evison squared him up and found the edge.
Finding some swing late in the day, Hutton won leg before verdicts against Dom Bess and Harry Duke but another 19-year-old, Matthew Revis made 34 with seven fours before he miscued to mid-off.
Batting for 11 overs in the late afternoon sunshine, the hosts lost Haseeb Hameed when he nicked Ben Coad to Lyth in the slips, but the pair of Ben Duckett and Ben Slater were able to carry the hosts to the close without further alarm.
