Liam Plunkett picked up four wickets as Yorkshire made short work of Northamptonshire on the final day to record their third LV= County Championship win of the season.
Hosts Northants began on 66 for three in pursuit of 432 for victory but, even with a delayed start to proceedings, they only lasted until mid-afternoon before being bowled out for 160.
Plunkett led the way as he claimed four of the final five wickets to fall as Yorkshire sealed victory by 271 runs, and in the process inflicted a fifth defeat in six matches on the home side.
England's Tim Bresnan was another to prosper, taking 3-46 from his 14 overs as the White Rose county picked up 19 points.
At Hove, Alex Hales hammered his first championship century in nearly two years, eventually making 167 from just 133 balls at Nottinghamshire took control in their match against Sussex.
The home side's Ed Joyce turned an overnight 104 into an unbeaten 164 in a first-innings total of 355 all out, but it was Hales' big hitting that dominated proceedings.
Nottinghamshire closed the third day with a commanding 404-run lead, after declaring on 336 for four in their second innings. Sussex will resume on 29 without loss on the final day, resigned to batting through to secure a draw.
With much talk about his chances of an England Test call-up, Middlesex opener Sam Robson did his claim no harm as he ended day three of their clash with Durham unbeaten on 42.
For his team, however, the prospects of success in this game look increasingly bleak. The visitors are 90 for two in their second innings and still trailing by 148 after being asked to follow on.
Resuming on Tuesday morning on 69-4 in their first innings, Middlesex succumbed to the pressure of chasing Durham's mammoth 568 for nine declared, being bowled out for 330, 89 short of the follow-on figure.
Mark Wood's 4-75 was largely responsible for pegging back the visitors, who then lost Australian Test star Chris Rogers and Dawid Malan before the close to leave themselves with plenty to do to save the game.
All-rounder Peter Trego starred with the ball as high-flyers Somerset chased an innings victory against Lancashire at Old Trafford.
The experienced Trego and Somerset's youngsters Craig Overton and George Dockrell each took three wickets apiece as Lancashire were bowled out for 203 in pursuit of Somerset's 420.
Then, after the home side were made to follow on, Trego dismissed Alex Davies, Paul Horton and Ashwell Prince cheaply to reduce Lancashire to 95 for three at the close on day three - still trailing by 122.
It would have been even worse for the Red Rose county but for a determined knock for Andrea Agathangelou, who finished the day unbeaten on 46 alongside Karl Brown (22).
Despite that, Somerset will still be hoping - weather permitting - to record their third victory of the season on the final day and possibly go top of the LV= County Championship Division One standings.
