Michael Lumb has turned down a new two-year deal at Hampshire and decided to join Nottinghamshire.
Lumb has spent the last five seasons with Hampshire but the offer of a three-year deal nearer to his Yorkshire roots was difficult to resist.
Nottinghamshire have been keen to sign a new opening batsman and their director of cricket Mick Newell said: “We’re delighted that Michael has agreed to join us and the meetings that we’ve had with him have been very constructive in terms of our respective ambitions and the role he sees himself playing in fulfilling them.
“We have been in the market for a proven batsman and we believe that he has the pedigree and the drive to improve our standing in all formats.”
Lumb, 31, said: “It has been a real pleasure to be involved in teams that have won two limited-overs trophies and finished runners-up in another.
“I would like to thank Rod Bransgrove, Giles White, and all of the fantastic players I’ve had a chance to play with for Hampshire, plus the Rose Bowl staff for helping make this my home for a hugely significant period in my development as a player and as a person.
“However, I feel that now is the right time to make a fresh start at a new club and, for that reason, I’m pleased to be offered the opportunity to play for Nottinghamshire. It’s a challenge and one I’m looking forward to.”
Hampshire chairman Bransgrove said: “Michael has been a good servant of the club and has made many important contributions to several successful campaigns.
“We’ve all been only too pleased to see him progress to the point where he has been involved for his country and, clearly, we’re disappointed to lose a player of his obvious talent. However, we wish him all the very best for the future.”
