Scouting Report: Shawn Armstrong

Summary

Shawn Armstrong, 35-year-old veteran reliever for the Cleveland Guardians, has been recovering from a right groin strain sustained in late April. He began a rehab assignment with Double-A Akron on May 12, 2026, and was successfully activated off the 15-day injured list on May 18. Before the injury, Armstrong posted a 1-0 record with a 4.22 ERA and 13 strikeouts over 10.2 innings in 12 appearances. His performance showed inconsistency with three poor outings accounting for most runs allowed, but he was dominant in nine other relief appearances. Armstrong brings 12 seasons of MLB experience with a career 3.83 ERA and 447 strikeouts. The Guardians signed him to a one-year deal to provide veteran depth and high-leverage relief options.
