Essex clinched a thumping 254-run win over Nottinghamshire in the Vitality County Championship, skittling their hosts for 80 at Trent Bridge as Sam Cook claimed a 10-wicket match haul.
Essex, runners-up to Surrey during the 2023 campaign, shredded their opponents in 34.3 overs in their second innings with Cook claiming 6-14 to add to figures of 4-59 first time around.
Joe Clarke (19) top-scored for Nottinghamshire and was one of only three players to make double figures, alongside Haseeb Hameed (10) and Matthew Montgomery (12).

The Chelmsford side could potentially lose their 16 points for a win if an offence is confirmed.
In 2022, Durham were docked 10 points after Nic Maddison's bat failed to fit through the measurement gauge.
Essex head coach Anthony McGrath said: "The match referee and the umpires were involved after the incident and now it will go to the ECB. We'll await news on that.
"They have got the bat in question and will go through whatever the process is involved and hopefully we will get to know within the next couple of days.
"It's not ideal [to be facing a potentially big penalty], but whatever happens it won't take away from what was a really good team performance."
Cook's display was a standout and the bowler hopes it impressed the England selectors as he eyes an international debut this summer.
"I'm desperate to play for England and hopefully that performance is something towards that but I'm trying to concentrate on playing for Essex," said Cook.
"In the past I've probably been guilty of chasing it a bit too much and getting caught up in that, but in the last six months I've tried to go back to basics and concentrate on what I do well."
