Yorkshire beat Warwickshire with a day to spare at Headingley to replace them as County Championship leaders.
Jack Brooks finished with seven wickets in the match as Warwickshire were bowled out for scores of 200 and 89 to slip to defeat by an innings and 155 runs late on day three.
Yorkshire's four-man seam attack all played their part with Liam Plunkett and Steven Patterson each taking four wickets - two per innings - and Tim Bresnan chipping in with 2-26 in the second innings.
Warwickshire had resumed on 136-6 in their first innings, needing a further 159 runs to avoid the follow-on.
They did not come close; Warwickshire skipper Ian Bell was last out for 97, caught behind off Brooks (3-39), and the visitors fared even worse following-on, their second innings lasting only 31.1 overs either side of a heavy downpour at tea that wiped out much of the evening session.
Yorkshire earned 23 points for their efforts and now sit 11 clear of Warwickshire.
Sussex could overtake Yorkshire with a victory in their match against Durham at Hove but that seems unlikely after rain limited day three to 45.2 overs.
Scott Borthwick's 84 not out guided Durham to 137-2 in reply to Sussex's first-innings of 505-9.
No 3 Borthwick, who had previously failed to register a half-century this summer, shared an unbroken 103-run stand with Kumar Sangakkara (30no) after coming together at 34-2.
Eoin Morgan completed his first championship hundred for five years as Middlesex moved into a good position to press for victory against Lancashire going into the final day at Lord's.
Morgan, on 76 overnight, advanced to 103 before edging behind off Tom Smith. John Simpson (50) and Ollie Rayner (77) then added 124 for the seventh wicket before Middlesex declared their first innings at 459-8, a lead of 193.
Lancashire lost Luis Reece, lbw to Tim Murtagh for two, on the way to 15-1 in their second innings at the close.
And at Trent Bridge, James Taylor and Riki Wessels led the way as Nottinghamshire recovered from 30-3 to reach 259-5 in reply to Northamptonshire's first-innings 248.
Taylor hit 11 fours in his 78 and Wessels was unbeaten on 78 from 94 deliveries to give the home side an 11-run advantage after three days, the first of which was a total washout.
