Right-handed reliever Seranthony Dominguez reached agreement on a two-year, $20 million contract with the Chicago White Sox, ESPN reported on Friday.
Dominguez, 31, is expected to serve as the closer for the White Sox, who have been active this winter.
Chicago signed Japanese slugger Munetaka Murakami to a two-year, $34 million contract last month. The White Sox also added left-handers Anthony Kay and Sean Newcomb as well as infielder Luisangel Acuna in the Luis Robert Jr. trade with the New York Mets on Tuesday.
Dominguez posted a 4-4 record with two saves and a 3.16 ERA in 67 relief appearances split between the Baltimore Orioles and Toronto Blue Jays last season. He joined the Blue Jays just prior to the trade deadline.
He owns a 23-23 record with 40 saves and a 3.50 ERA in 322 career relief appearances for the Philadelphia Phillies, Orioles and Blue Jays.
