Starting pitcher Mike Clevinger is back with the Chicago White Sox on a 1-year deal

Mike Clevinger is returning to the Chicago White Sox.

The right-hander, who went 9-9 for the Sox last season, agreed to a one-year contract Monday, a source confirmed to the Tribune. Terms were not disclosed. The move is pending a physical.

Robert Murray of FanSided had the initial report.

Clevinger, 33, was at times the most effective Sox starter in 2023. He had a 3.77 ERA and 110 strikeouts in 24 starts. Clevinger declined a mutual option in November.

He potentially would join a rotation that includes Garrett Crochet, Michael Soroka, Erick Fedde and Chris Flexen.

Brad Keller, who signed a minor-league deal with the Sox in March, is building up. Another option could be minor-leaguer Nick Nastrini, who pitched well during spring training.

Clevinger previously pitched for Cleveland (2016-20) and the San Diego Padres (2020, 2022). He missed the 2021 season after Tommy John surgery on his right elbow.

The Sox signed Clevinger to a one-year, $12 million deal before last season, announced in December 2022. In March 2023, Major League Baseball notified him that it wouldn’t impose discipline after investigating allegations of domestic violence and child abuse. The Sox said they didn’t know of the allegations or the investigation at the time of the signing.

Clevinger has a 60-39 record with a 3.45 ERA in 152 career outings (138 starts) over seven seasons.
