The Chicago White Sox have designated struggling right-hander Ervin Santana for assignment.
The two-time All-Star was 0-2 with a 9.45 ERA in three starts after his contract was purchased from Triple-A Charlotte on April 9. The White Sox signed him to a minor league deal in February. A finger injury limited him to five appearances with Minnesota last season.
The 36-year-old Santana is 149-127 with a 4.09 ERA over 15 seasons with the Los Angeles Angels, Kansas City, Atlanta, Minnesota and Chicago.
Also Friday, the White Sox reinstated outfielder Eloy Jimenez from the bereavement list. He had returned home to the Dominican Republic following the death of his grandmother.
