The Chicago White Sox and right-handed reliever Seranthony Domínguez agreed to a two-year, $20-million contract, sources told ESPN's Jeff Passan.
Domínguez, 31, authored a 3.16 ERA and 3.47 FIP over 67 appearances between the Baltimore Orioles and Toronto Blue Jays last year.
He's expected to close for the White Sox, Passan adds.
