According to FSN's Tyler Mason, Twins Doctor John Steubs said that Perkins' ulnar collateral ligament "looks perfect." He also noted that the forearm strain will be managed with exercise and therapy.
Earlier this week, Parker Hageman asked What was going on with Glen. Specifically, he wrote about his declining fastball velocity.
Perkins has experienced this forearm issue before but not to this degree. The most important thing is that the UCL is intact. That is actually good news.
He is expected to be ready for spring training.
