Joey Evison, Nottinghamshire's former England Under-19 allrounder, has signed a three-year contract with Kent. He will also join the club on loan for this year's Royal London Cup.
Evison, 20, debuted for Notts in 2019 and has since made 10 first-class appearances, alongside five in List A and one T20. He recorded his maiden first-class hundred earlier this season but has seen opportunities limited by the development of fellow seam-bowling allrounder Lyndon James.
Evison currently averages 27.13 with the bat in first class cricket, and 30.19 with the ball, having taken a maiden five-wicket haul against Durham last summer.
"I couldn't be more excited about joining Kent Cricket," Evison said. "I recognise that I'm still young but I'm hungry for first team cricket and very much hope I'll be able to achieve this at Canterbury, as well as helping the team to success in the coming years."
The signing could be the start of a rebuilding process at Kent, who saw seamer Matt Milnes agree terms with Yorkshire on Friday and have to start preparing for life after Darren Stevens, with the 46-year-old allrounder having only made seven first-team appearances this year.
Kent's director of cricket, Paul Downton, said: "I'm delighted that Joey has chosen to join Kent. He's an exciting talent with the potential to bat in the top order and also be a threat with the ball. He's a really hard worker and we're convinced that he will be a quick learner too, as opportunities come his way.
"We're also really pleased to have Joey available for us in this season's Royal London Cup, and he strengthens our 50-over squad ahead of the tournament.
"This is a signing with both the present and the future in mind. We can't wait to see Joey blossom and make a positive impact both on and off the field for Kent."
