Chicago White Sox pitcher Mike Clevinger is under investigation by Major League Baseball following allegations of domestic violence involving the mother of his 10-month-old daughter and child abuse.

Olivia Finestead, the 24-year-old mother of Clevinger’s child, told The Athletic on Tuesday that she has been in contact with individuals from MLB’s Department of Investigations since this summer. According to Finestead, she has detailed to those investigators incidents of physical, verbal and emotional abuse, including an incident from last June in which Finestead said Clevinger choked her, and another about two weeks later when she said Clevinger slapped her in a hotel room when the team was playing the Dodgers and threw used chewing tobacco on their child.

A source familiar with MLB’s investigation process confirmed there is an open investigation on Clevinger. The source added that the White Sox became aware of the allegations after he was signed.

Clevinger, 33, reached via text message said his agent and lawyer would contact The Athletic. Asked for an on-the-record statement before publication, Clevinger’s agent, Seth Levinson wrote in a text message: “We need to fairly and thoroughly protect our client and at the same time be respectful of the White Sox and MLB. We need time before responding.”
