Ant Botha has signed a two-year contract with Warwickshire after turning down an extension with Derbyshire.

"It has been a very difficult decision," Botha said. "At this stage of my career, I feel this is the right move for me and an exciting opportunity that I might not get again."

John Morris, Derbyshire's director of cricket, admitted he was "very disappointed" to lose Botha mid-season but stressed it would give him a chance to "assess players in the remaining matches this year who are going to be a part of Derbyshire's future".
