CHICAGO -- Reliever Buddy Carlyle landed on the disabled list Wednesday with lower back and hamstring issues. Left-hander Jack Leathersich will be promoted from Triple-A Las Vegas, although he is not due to join the big league team until Thursday's matinee series finale.

Leathersich, Chasen Bradford and Zack Thornton received consideration for the call-up, but Leathersich is the only one of that trio already on the 40-man roster.

Leathersich made two late-April appearances with the Mets.

Carlyle was forced to depart Monday's series opener at Wrigley Field after back spasms intensified covering first base.
