Both Coulombe and Sean Poppen were added to the Twins' active roster Saturday, Aaron Gleeman of The Athletic reports.
Coulombe has already seen limited action at the major-league level over a span of seven years. The left-hander was most recently a part of the Athletics in 2018, when he registered a 4.56 ERA along with a 26:11 K:BB across 23.2 innings. He's a viable option as a middle reliever, at best.
