Yorkshire clinched their first LV= County Championship title since 2001 after wrapping up an emphatic innings and 152-run victory over Nottinghamshire on the final morning at Trent Bridge.
Needing just five wickets on day four to secure their 31st title, Yorkshire, thanks to Ryan Sidebottom’s six-wicket haul, completed the task in just over an hour's play and with a round of fixtures to spare.
Former Notts left-arm seamer Sidebottom returned to haunt his own team with figures of 6-30, including the winning wicket of James Taylor, to spark scenes of wild celebration on the outfield.
Sidebottom started the ball rolling in the third over by bowling nightwatchman Gary Keedy for a duck and then found Chris Read’s edge through to Jonny Bairstow to move the White Rose a step closer.
Luke Fletcher was the next to depart, edging Sidebottom to Adam Lyth at second slip and leg-spinner Adil Rashid put Yorkshire on the brink when he trapped Jake Ball lbw for a duck.
Warks into second
England hopeful Taylor fought valiantly for his 75 but was the last man out when he slashed Sidebottom to sub fielder Richard Pyrah at backward point to seal an eighth and decisive victory.
Sidebottom, 36, has now won the County Championship on four occasions, twice with Notts, and now twice with the county of his birth.
The heavy home defeat means Notts must now battle it out with Warwickshire for the runners-up consolation prize on the final week of fixtures.
Warwickshire moved into pole position to secure the runners-up spot with a crushing innings and 16 runs victory over Northamptonshire later on Friday and they could secure second spot next week if Nottinghamshire fail to beat Sussex at Trent Bridge.
Northamptonshire's defeat was their 11th in 14 matches in a wretched season and their seventh by an innings and the only bright spot was another innings of promise from Ben Duckett.
The former England Under-19 captain followed up last week's maiden century against Somerset with a busy 71 but it was not enough to make Warwickshire bat again as they were dismissed for 284 in their second innings.
Keith Barker was the pick of the Warwickshire bowlers, finishing with figures of 4-47 from 20.2 overs.
At Lord’s, Durham secured their place in Division One for another season and plunged Middlesex into the relegation scrap with an impressive 141-run victory.
Paceman Chris Rushworth led the way with three wickets for 74 runs as the Londoners were dismissed for 254 in pursuit of the 396 victory target on day four.
The defeat for Middlesex leaves them in a precarious position although the clear favourites to suffer the drop must be Lancashire after they allowed Sussex to complete a swift run chase and win by seven wickets at Hove.
The home side banished any fears that they might be dragged into a battle at the bottom of the table by chasing a target of 251 in 59 overs with 12.3 overs to spare with skipper Ed Joyce, Chris Nash and Craig Cachopa all making half-centuries.
That leaves Lancashire on the brink of a second relegation in three years as they sit second from bottom, 12 points behind Middlesex.
The sides meet at Old Trafford in the final match but Middlesex have a game in hand against Somerset at Taunton starting on Monday.
