Yorkshire were kept waiting on the brink of their first title in 13 years as James Taylor revealed some belated Nottinghamshire resistance at Trent Bridge.
Reprising his captain Chris Read’s defiance in a first-innings 203 all out, and benefiting from one of two significant Yorkshire fumbles when he was dropped in the slips on one by Gary Ballance off Ryan Sidebottom, Taylor (56no) dug in to take the hosts to 149 for five.
Yorkshire took 11 wickets on the day, bowling out the hosts for 203 and leaving them on 149-5 at the end of the second day.
So they still had work left for the final day as they seek to wrap up their 32nd title with a match to spare.
Only Read (81no) kept the champions elect at bay for long in Notts’ first descent on another sunny morning and were bowled out in only 66.2 overs when the number 11 fell lbw.
They would need to last a whole lot longer second time round to make Yorkshire sweat.
Yet they lost Steven Mullaney to the very first ball, lbw when Sidebottom went full but perhaps pitched marginally outside leg, and then Lumb edged Brooks to third slip in the second over.
Yorkshire’s unexpected generosity kicked in before tea, though, Hales dropped first on four by Adam Lyth at second slip off Sidebottom - and then Taylor escaping too.
The third-wicket pair put on 62 before Hales drove a sharp return catch back at a perfect height for Brooks in his follow-through, and Yorkshire did not strike again until the final hour when Jonny Bairstow was alert - and Samit Patel most definitely was not, stumped casually lifting his back foot with the wicketkeeper standing up to Steve Patterson.
Wessels also went before the close, for the second time in the day, bowled on the back foot pushing across one from Sidebottom that did not get up much.
But Taylor was in no mood to make it easy for Yorkshire again - and as he chiselled out a gritty 94-ball half-century, it dawned on one and all that they would be back for more on Friday after all.
