Manaea's MRI showed his injury is "muscular and minor" in nature, Jane Lee of MLB.com reports.
Many feared the worst after Manaea left Monday's game with a pronator muscle strain in his left forearm, but fortunately, no ligament damage was found in his MRI. As a result, the team is optimistic Manaea could make a quick turnaround, perhaps after missing just the minimum 15 days. Zach Neal is an option to start a couple games in the meantime.
