Triceps

February 28, 2026

Peterson was diagnosed with a right triceps strain Saturday and will require roughly 6-to-8 weeks of recovery time, Tim Stebbins of MLB.com reports.

Analysis
Peterson suffered the injury during his appearance in Tuesday's Cactus League game against the Dodgers. He won't be able to make another appearance this spring and will almost certainly begin the regular season on either the Guardians' injured list or Triple-A Columbus' IL.
