Veteran left-hander Ross Detwiler has signed a $850,000, one-year contract with the Miami Marlins, whose primary offseason goal is to upgrade their bullpen.

The Marlins also announced the signing of catcher Sandy Leon to a minor league contract with an invitation to major league spring training. Left-hander Stephen Tarpley was designated for assignment.

Detwiler pitched in 16 games out of the bullpen for the Chicago White Sox in 2020, going 1-1 with a 3.20 ERA in 44 innings.

Leon batted .136 in 25 games last year for Cleveland. He has a .216 career average in nine seasons with three teams.
