The Chicago White Sox designated right-hander Mike Clevinger for assignment following a 12-3 loss to the Athletics, where Clevinger allowed three runs in the ninth inning. Clevinger, who primarily served as a starter throughout his career, has struggled this season with an 0-2 record and a 7.94 ERA in five relief appearances. He signed with the White Sox in free agency and holds a career record of 9-14 with a 4.24 ERA in his time with the team.
In response to Clevinger's designation, right-hander Steven Wilson was called up from Triple-A Charlotte. Wilson, acquired in a trade with San Diego, had a 1.69 ERA in five relief outings in Charlotte but posted a 5.71 ERA in 40 appearances with the White Sox last year. Clevinger, a seasoned pitcher with a 3.55 ERA over nine seasons, made his MLB debut with Cleveland in 2016 and also played for the Padres before joining the White Sox.
