TOM Kohler-Cadmore will join Yorkshire on Monday after signing a three-year contract at Headingley.
Kohler-Cadmore has been granted an immediate release from Worcestershire, where he was out of contract at the end of the season.
He is ineligible for the latter stages of the Royal London Cup, having not played for Yorkshire in the group stages.
The top-order batsman, 22, will also be unavailable for matches against Worcestershire this season.
Kohler-Cadmore played junior cricket for Yorkshire and his family still live in Hornsea near Hull, while his brother Ben plays for Driffield Town.
"Obviously it was a massive decision to move home – and I find it incredibly exciting," he said.
"Yorkshire was my childhood county. I played in the under-13s, 14s and 15s and I can't wait to join what I see as the best club in the country.
"Part of my decision to move was to challenge and test myself in what is a great environment and a very strong squad. Hopefully this will help me improve and push me on to higher levels.
"I remember how professional the club is and the pride that all the players have in wearing the White Rose.
"I'm thoroughly looking forward to pulling the shirt on, turning in some good performances and contributing where possible to some success.
"I've loved my time at Worcestershire. It will always have a special place in my heart.
"I'd like to thank them for all the opportunities they have afforded me, as well as the support I've received from both the players and fans."
Kohler-Cadmore's senior Yorkshire debut could come in a second XI Championship match against Lancashire at Scarborough, starting on Tuesday.
