CHICAGO -- The White Sox placed second baseman Lenyn Sosa on the 10-day injured list because of a strained right hip flexor and recalled first baseman Tim Elko from Triple-A Charlotte on Wednesday.
Chicago transferred right-hander Miguel Castro to the 60-day IL with a torn patellar tendon in his right knee prior to its game against the Tigers. The White Sox also claimed righty Ryan Cusick off waivers from the Tigers and optioned him to Charlotte.
Sosa, 25, is batting .274 with four homers and 17 RBIs in his fourth season.
