Shawn Armstrong is back. The Cleveland Guardians right-hander returned from the injured list on Wednesday, September 23, with the team confirming his roster activation. The move adds a bullpen arm back into the mix for Cleveland as the regular season heads toward its final days.

What Armstrong's Return Means for the Bullpen

Armstrong has established himself as a versatile bullpen arm capable of handling multiple roles for Cleveland — closing, bridging, and entering with runners on base. His return adds a proven option back to a pitching staff that has been without him during his time on the injured list. Full 2025 statistics for Armstrong were not available in confirmed sources at the time of publication and will be updated when verified.

Timing of the Return

Armstrong's return comes with the regular season in its closing stretch. The Guardians now have him available at Progressive Field as the roster pushes through September. His active status was confirmed as of September 23, and Cleveland will look to integrate him back into the bullpen mix immediately.

There are no current active streaks tied to Armstrong coming off the injured list, and his exact injury details were not disclosed in available information. What is known is straightforward: he is back, he is active, and a bullpen that leaned on his arm heavily in 2025 has him available again when it counts.
