The Twins reassigned Coulombe to their minor-league camp Sunday, Betsy Helfand of the St. Paul Pioneer Press reports.
Coulombe, who was attending big-league spring training as a non-roster invitee, is expected to report to Triple-A St. Paul to begin 2021. The 31-year-old lefty boasts 155 games of big-league experience, so he could be on the short list for a promotion if the Twins need a lefty reliever at any point.
