Lands on IL The Mariners recalled Kowar from Triple-A Tacoma and placed him on the 15-day injured list Wednesday with a right shoulder impingement, retroactive to Aug. 19.
Impact Kowar was sent down to Triple-A in mid-August but hasn't pitched for Tacoma since being demoted. Now dealing with a shoulder issue, the 28-year-old will return to the big-league club to rehab his injury. He'll be eligible to return from the IL as soon as he's healthy, but there's currently no telling how close he is to activation.

Back with M's The Mariners recalled Kowar from Triple-A Tacoma on Thursday.
Impact Since being optioned to Triple-A in mid-June, Kowar has given up six runs (three earned) over nine innings while striking out 12 batters and walking seven. He owns a 2.08 ERA through 8.2 frames with the Mariners this year, but his career 8.38 ERA will keep him limited to a low-leverage role in Seattle's bullpen. Brandyn Garcia was optioned to Tacoma in a corresponding move.
JULY 24 • ROTOWIRE
Optioned to Triple-A The Mariners optioned Kowar to Triple-A Tacoma on Monday, Shannon Drayer of SeattleSports.com reports.
Impact The transaction frees a spot on the active roster for the return of Logan Gilbert (elbow). Kowar made seven appearances after being activated late last month, yielding two runs with an 8:3 K:BB over 8.2 frames.

Reinstated from IL The Mariners reinstated Kowar (elbow) from the 60-day injured list Wednesday.
Impact Kowar will return to the majors after missing the entire 2024 season following Tommy John surgery last March. The 28-year-old right hander posted a 2.57 ERA and 1.29 WHIP across seven innings during his rehab assignment and did not yield a run in each of his last three outings. Kowar will be available to make his 2025 debut out of the Mariners' bullpen against the Nationals on Wednesday. Logan Evans was optioned to Triple-A Tacoma in a corresponding move.
MAY 28 • ROTOWIRE
Closing in on return Kowar (elbow) could be nearing his activation from the 60-day injured list, MLB.com reports.
Impact Kowar has produced solid results in the minor leagues amidst his recovery from 2024 Tommy John surgery, posting a 2.57 ERA, 1.29 WHIP and 4:3 K:BB over seven innings (eight appearances) on his rehab assignment. The 24-year-old right-hander should be ready to make both his Mariners and season debut by early June, and he'll likely operate as a multi-inning reliever in Seattle's bullpen once he's fully up to speed.
