Wayne Madsen has been appointed captain of Derbyshire following the retirement last week of Luke Sutton.
The 27-year-old batsman has made 39 first-class appearances since scoring 170 not out on debut against Gloucestershire in 2009, the highest ever score by a Derbyshire debutant.
He has since compiled 2,476 first-class runs at an average of 35.88, including nine centuries.
Madsen has also become an integral member of the team in Limited Overs cricket and in 2011 averaged 43.45 in the Clydesdale Bank 40 competition with four half-centuries, plus a further three fifties during the Friends Life t20 campaign.
Madsen is South African-born and is due to complete England qualification early in 2013. He captained the side in four List A matches in 2011.
Madsen played international hockey for South Africa prior to becoming a professional cricketer.
He said: “I’m excited and extremely honoured to be handed the role.
“I’m looking forward to the challenge of leading an exciting young team into the new season.
“It will be a privilege to lead this group of players and I’m looking forward to working closely with Karl Krikken as we strive to get the best out of our young and talented squad.”
Derbyshire Head Coach Karl Krikken said: “As an excellent leader within the squad and as a model professional, Wayne is the ideal candidate to take over captaincy duties.
“He proved to be a very popular stand-in captain in one-day cricket during the latter part of last season and I know he will do an excellent job in the position on a full-time basis.
Derbyshire chairman Chris Grant added: “My sincere congratulations to Wayne on this fully deserved honour.
“I’m sure all the club’s members, supporters, sponsors and partners join me in wishing him all the very best for the season ahead.”
