The 20-year-old has made three first-class outings for the Trent Bridge club after impressing for the second XI
Nottinghamshire have awarded Liam Patterson-White a professional contract following his ascent into the first team the season.
The 20-year-old has made three County Championship outings for Notts in 2019, during which he has scored 75 runs and taken 16 wickets.
Those performances have included a maiden five-for on debut against Somerset and a half-century against Yorkshire in August - leading to the offer of a pro deal.
Patterson-White, who has penned a three-year deal, has previously been on England's radar having represented the Under-19 side.
“It is an absolute privilege to have signed my first pro deal. It’s not really sunk in yet,” he said.
“I’ve been working towards this dream for a number of years and to achieve it is really special.
“My next goal is to cement myself in the red-ball side next summer and continue the form I’ve found at the end of this season.

“I’ll be putting hard graft in over the winter to improve my consistency and to show people how much I want to play for Nottinghamshire.”
Head coach Peter Moores added of the left-arm spinner: “For a young player, the first professional contract is always a special moment because it tends to mean they’ve achieved a longstanding ambition.
“Liam’s attitude and performances since coming into the side have been outstanding.
“He’s a local cricketer who has come through the age-group and Academy system, played some good cricket in the seconds and got his chance in the first team on the back of that.
“It makes him a good example of how the pathway should work. And once he was in the first team, his performances have been enough to show that he has a bright future.”
