Zak Chappell has agreed a three-year contract with Nottinghamshire after deciding to quit Leicestershire.
The 22-year-old became one of the hottest properties in English cricket in 2018, taking 16 wickets in the County Championship at an average of 15.93.
The all-rounder also averages over 30 with the bat in first-class cricket and becomes the third new signing ahead of the 2019 season, after Ben Slater and Ben Duckett both joined on three-year deals earlier this summer and moved to Trent Bridge on loan.
Chappell, who rejected two-year and one-year deals offered to him by Leicestershire to follow the path previously taken across the Midlands by Stuart Broad, James Taylor and Harry Gurney in recent years, said: "This is a dream move for me and I'm excited to get started at such a prestigious club.
"Nottinghamshire have a top-quality squad and I think it will be the perfect place for me to take my game to the next level.
"Being able to call Trent Bridge my home and to play alongside the likes of Stuart Broad, Alex Hales and Jake Ball will be a dream come true."
Nottinghamshire won the limited-overs cup double in 2017 as well as gaining promotion to the top flight of the County Championship.
However, that success combined with the loss of players such as Chris Read, Michael Lumb and Brendan Taylor in recent months has led to a period of consolidation.
Meanwhile, Lancashire are 5/2 to win this weekend's Vitality Blast. Somerset can be backed at 11/4, Sussex at 13/5 and Worcestershire at 3/1.
