The Colorado Rockies swapped minor league relievers with the Chicago Cubs on Monday, each of whom has seen big league time over the last calendar year and were subsequently designated for assignment.
Colorado acquired left-handed reliever Zac Rosscup from Chicago for right-hander reliever Matt Carasiti.
Rosscup was added to the Club’s 40-man roster and was optioned to Triple-A Albuquerque. This leaves the Rockies 40-man roster at a full 40. Rosscup has spent parts of four seasons in the majors going back to 2013. He was designated for assignment late last week.
