England Lions opener Stephen Moore has joined Lancashire on a two-year deal.
Moore, 28, activated a release clause in his contract with Worcestershire following the county's relegation from Division One of the LV County Championship.
The South African-born right hander is aiming to use the switch to push his claims for a full England call-up.
"To join a club of Lancashire's stature is a fantastic opportunity for me at this stage in my career," Moore told Lancashire's official website.
"I am confident that the club will provide me with the platform to grow and develop as a player and person.
"I look forward to being a part of the club's future development, and will strive to contribute in everyway I can to the success of the team on and off the field."
Fantastic
Lancashire head coach Peter Moores added: "It's fantastic news that Stephen has decided to join Lancashire.
"We were keen to secure his services and are delighted he shares the same vision that we have for this great club.
"Not only is he a quality cricketer but has all the attributes and characteristics we look for in a person. We look forward to seeing Stephen play an important role in the future success of the team."
Moore averaged just 27 in 14 championship matches last season but did score a century for the Lions against Australia.
He has scored 6,862 first-class runs at an average of 40.12, including 15 hundreds, since his debut in 2003.
