The Boston Red Sox placed right-hander Clayton Mortensen on the disabled list Tuesday with a hip/groin condition that has been bothering him since early April and recalled Jose De La Torre to help an overtaxed pitching staff that is in need of fresh arms. De La Torre is expected to be activated just Tuesday night for insurance purposes and then will be sent back to Pawtucket to make room for Alfredo Aceves, who will start on Wednesday against the Rays.
