June 16, 2025 5:50 PM : The Mariners optioned Kowar to Triple-A Tacoma on Monday, Shannon Drayer of SeattleSports.com reports.
Analysis: The transaction frees a spot on the active roster for the return of right-hander Logan Gilbert (elbow) from the injured list. Kowar made seven appearances after being activated from the 60-day injured list late last month, yielding two runs with an 8:3 K:BB over 8.2 frames.
