White Sox designate Mike Clevinger for assignment, promote Steven Wilson

The Chicago White Sox designated pitcher Mike Clevinger for assignment after he struggled in his new bullpen role, posting an 0-2 record and a 7.94 ERA over eight relief appearances this season. Clevinger, who had neck surgery earlier in the year and recently returned, was replaced on the roster by Steven Wilson, who has been effective in Triple-A with a 1.69 ERA. Clevinger cleared waivers unclaimed and can elect free agency or accept an outright assignment to Triple-A Charlotte. Meanwhile, the Boston Red Sox designated Michael Fulmer for assignment after a difficult return from UCL surgery, raising the possibility of a trade or waiver claim due to his pitching versatility. These moves reflect both teams' efforts to adjust their pitching staffs amid challenging seasons. The White Sox, in particular, are hoping roster changes will help them improve on a slow start to the year.
