Chesterfield-born Ben Slater has signed a two-year contract with Derbyshire.
The 23-year-old batsman has scored 423 runs, in six matches, at an average of 35.25 since breaking into the LV= County Championship team in July, including three half-centuries.
Former Netherthorpe School pupil Slater said: “I’m thrilled to commit my future to my home county. I feel like my game has come a long way this year working closely with the coaching team.
“I’ve been around the first team for a few years and now it’s important that I secure a place at the top of the order and contribute runs to a successful Derbyshire team.”
Derbyshire’s elite performance director Graeme Welch said: “Ben is a home-grown talent who has come through the ranks and - at 23 years old - has the potential to become a consistent performer.
“He has impressed me since returning to the four-day side. He’s a talented cricketer and a proud Derbyshire lad who our members and supporters really root for.
“This is reward for the effort Ben has put in throughout pre-season training and during the summer. It has really started to pay off.
“He has become more confident at the crease and is starting to know his own game very well. It’s now important that Ben carries on improving and becomes the player we know he can be.”
