Derbyshire have released batsman Dan Redfern by mutual consent, despite the 23-year-old still having two years left to run on his contract. Redfern lost his place in the first team last season, as Derbyshire were relegated in their first Division One campaign in a decade.
A graduate of the club's academy, Redfern enjoyed his best season in 2012, scoring 792 runs at 37.71 - including his maiden first-class centuries - as Derbyshire won promotion as Division Two champions. He signed a three-year contract extension at the end of 2012 but suffered from injuries and a loss of form.
"Dan's been with the club since joining the academy in 2004 and we thank him for his efforts during that period," Derbyshire's head coach, Karl Krikken, said. "However, in recent times, he's had a number of issues - both on and off the field - which made last season in particular a challenging time for both him and the club.
"While it's always difficult to see players leave, both Dan and the club feel a new challenge is the best route forward."
Having made his debut as a 16-year-old in 2006, Redfern was part of a talented crop of young players to emerge under Krikken's guidance of the academy. He was a member of England's team at the 2008 Under-19 World Cup and became a regular in Derbyshire's Championship side from 2009 onwards. This year, however, he managed just two half-centuries, averaging 16.80 from eight first-class appearances.
Redfern said: "I have thoroughly enjoyed my time at Derbyshire and I thank 'Krikk' and the team for their support. The decision to move on is tough but a fresh start will open new opportunities for me in the next stage of my career."
