Essex have lifted cricket's county championship trophy for the first time in 25 years after thrashing Yorkshire in Chelmsford.
Watch the celebrations and interviews with Alastair Cook and Simon Harmer
Sam Cook took five for 20 to help skittle Yorkshire for just 74 runs as Essex celebrated their title triumph in style.
The champion's 10th victory of the 14-game campaign was followed by resounding applause and sprays of champagne.
For Yorkshire, who secured their safety on day one, their total was their lowest since 1999 as they succumbed to a massive 376-run defeat in just 29 overs.
There were still 25 overs remaining in the day when Matt Fisher was left on his back by Neil Wagner to end the season with Essex unbeaten.
Cook, who made his first-class debut for his home county less than two months ago, had taken a career-best five for 18 in the second innings at Southampton in the last game.
The young fast bowler put the skids under a Yorkshire top-order chasing an unlikely 451 to win with four wickets in 32 balls in a six-over burst.
Adam Lyth looked surprised to be given out caught behind to Cook's second ball and Kraigg Brathwaite played down the wrong line to be lbw to Jamie Porter in the next over.
Alex Lees' middle stump was sent cartwheeling by Cook and Yorkshire were already on an inexorable slide at 17 for three.
Cook claimed his third wicket for 11 runs when the Ashes-bound Gary Ballance fell lbw for just five.
Jack Leaning was stuck in his crease playing forward and edging to James Foster to give Cook wicket number four.
Essex County Cricket Club also announced that opening bowler Jamie Porter has signed a two-year contract extension.
Porter will remain with the Club until 2020 at least.
The 24-year-old has taken 50 wickets for the third year in a row and emerged as one of the finest bowling talents in the country.
