Somerset have announced that director of cricket Dave Nosworthy will leave the club at the end of the season following a mutual agreement.
The South African, who was appointed to the post in December 2012, plans to return to his home country with his family.
“Both the club and Dave have mutually agreed that it is in the best interests of Somerset County Cricket Club to part company at the end of this season,” Somerset chief executive officer Guy Lavender said in a statement.
“Dave will leave with our thanks for all he has done and our best wishes for the future.
“We still have a critical part of the season remaining with Dave in charge and all of our immediate efforts are focused on beating Northamptonshire in our LV= County Championship match which commences on Sunday.
“The process of recruiting Dave’s successor is underway and an announcement will be made in due course."
Nosworthy, a former coach of South Africa’s Under-19s and A team, saw Somerset fall just short of reaching the quarter-finals of both the NatWest T20 Blast and Royal London One-Day Cup this season.
Somerset sit fourth in the LV= County Championship with three games remaining and retain an outside chance of winning the Division One crown.
“I believe the time is now right for me to return home with my family for a number of personal and business reasons and for me to redirect my own personal energies and ambitions,” Nosworthy said.
“With me being the type of character to always put the club and the team first, I believe I have done as much as I can and that the time is now right to step aside.
“There have been highs and lows, and some tough decisions to have been made along the way, but what has been most pleasing to me has been the emergence of some of the younger players who have flourished and have really come through in recent months.
“I have personally learnt a lot over the last two years about people and cricket, and look forward to taking this knowledge and these experiences along with me in to the future.
“Lastly, I’ve really enjoyed my time at the club and it will always have a special place in my heart. I would like to thank the club, the players, the members and staff for allowing me to be part of Somerset and for your patience and help along the way.”
