Durham on the brink of title
Durham are on the verge of their third LV= County Championship title, with just 62 runs required on Thursday to secure the silverware.
Victory over Nottinghamshire is enough to guarantee Durham the Division One crown, which they won back-to-back in the 2008 and 2009 seasons, and now appears a formality on day three.
Having blown their opponents away for 78 in the first innings at Emirates ICG, Durham managed 246 all out - with captain Paul Collingwood left hanging on 88 not out.
They then dismissed their opponents for the second time in the match, albeit for an improved 246 as the outside chance of an innings victory disappeared.
Graham Onions was again to the fore, taking three for 50 while all-rounder Ben Stokes, fresh from England's one-day series against Australia, took three for 55 after shaking off a hamstring problem.
Durham were left with a meagre 69 to win and chalked off seven of them in their only over before stumps.
Weather allowing, their coronation awaits.
Erstwhile title rivals Yorkshire ended day two against Middlesex with a workable lead, though it paled alongside Durham's efforts.
They slumped from 109 for three overnight to 210 all out - claiming just one bonus point as Tim Murtagh and Corey Collymore shared six wickets at Headingley.
That may have deflated their hopes but their bowlers gave no sign of that as they rolled Middlesex for 128. Ryan Sidebottom's fine season continued with four for 27, while Steven Patterson and Jack Brooks bagged three apiece.
Yorkshire go into day three on four without loss.
Rock bottom Surrey had one of their better days in a troubled season, making 400 for five against Warwickshire at Edgbaston.
Veteran Vikram Solanki made 162 in 246 balls, sharing a stand of 182 with fellow centurion Steven Davies (103).
In Division Two, champions-elect Lancashire fought back against Gloucestershire at Bristol on the back of Luke Procter's maiden first-class century.
Procter made 106, bettering a previous best of 89, to lift the Red Rose from 38 for three at the start of play to 292 for seven.
It enabled the visitors to move two bonus points nearer the title, having already clinched promotion.
Second-placed Northamptonshire toiled against Kent as the hosts piled on 418 all out.
Rob Key (101) and Brendan Nash (107) both cashed in, but James Middlebrook plugged away to return six for 78.
Essex's clash with Glamorgan at Chelmsford looked evenly poised with the home side 107 for one in reply to 322.
David Masters' five-wicket haul did most to restrict the Welsh side to that score, while Jaik Mickelburgh's 68no led the response.
It was a batsman's day at Grace Road as Hampshire pair Liam Dawson (136no) and James Vince (145no) plundered 248 runs in an unbroken third-wicket stand.
Bottom club Leicestershire used nine bowlers but could prise their pair apart and will reprise their attempts in the morning with the visitors 362 for two.
