With Chris Rusin starting the season on the injured list with upper back tightness and Jake McGee recently added to the injured list with a knee strain, left-handers are at a premium in the Colorado Rockies bullpen. There are currently just two on the active roster — Mike Dunn and Harrison Musgrave.
Musgrave’s role is unique in that, while he may be called upon in a certain situation, he is also designated as “the long reliever” right now, meaning he has to be ready to throw multiple innings if needed.
