Kowar cleared waivers Thursday and was sent outright to Triple-A Norfolk, Roch Kubatko of MASNSports.com reports.

EDGE Analysis

Kowar lost his place on the 40-man roster Wednesday after giving up three runs (one earned) over six innings during spring training, but he'll remain within the Orioles organization after passing through waivers unclaimed. The 29-year-old posted a 2.57 ERA over 14 frames in Triple-A last year and could work his way back into the majors if he performs similarly in 2026.

The Orioles designated Kowar for assignment Wednesday.

EDGE Analysis

Kowar was unable to win a spot in the Orioles' Opening Day bullpen after yielding three runs (one earned) on five hits and four walks across six innings during the Grapefruit League. The 29-year-old righty will now be exposed to waivers but could remain in the organization as relief depth at Triple-A Norfolk if he doesn't get claimed.

Kowar (shoulder) made his Grapefruit League debut in Thursday's 6-5 win over the Tigers, issuing one walk and allowing no hits over a scoreless inning of relief.

EDGE Analysis

Kowar looks to be back to full health after he spent the final month of the 2025 season on the Mariners' injured list due to a right shoulder impingement. After Seattle waived Kowar in January, he caught on with the Twins before being traded to the Orioles less than two weeks later. The right-hander is competing for a spot in Baltimore's Opening Day bullpen this spring.

The Twins traded Kowar (shoulder) to the Orioles on Saturday in exchange for cash.

EDGE Analysis

The Twins DFA'd Kowar on Thursday to make room for Anthony Banda, and the former will now find a home on Baltimore's 40-man roster. The 29-year-old righty finished 2025 with a 4.23 ERA and 1.24 WHIP across 17 innings with the Mariners and will have to break camp with the O's in order to keep his roster spot. Colin Selby (shoulder) was placed on the 60-day IL in a corresponding move.

The Twins designated Kowar (shoulder) for assignment Thursday, Dan Hayes of The Athletic reports.

EDGE Analysis

The transaction clears a 40-man roster spot for Anthony Banda, who was acquired via trade Thursday. Kowar was a waiver claim of the Twins earlier this month and could now be on the move again. He ended last season on the injured list with a right shoulder impingement, and it's unclear what Kowar's current health status is.

The Twins claimed Kowar off waivers from the Mariners on Tuesday.

EDGE Analysis

The right-hander was designated for assignment by the Mariners last week after they acquired Jhonny Pereda from the Twins, so this ended up being somewhat of a trade. Before landing on the injured list with a shoulder impingement in August, Kowar posted a 4.24 ERA, 1.24 WHIP and 15:7 K:BB across 17 innings out of the bullpen for Seattle.

The Mariners designated Kowar (shoulder) for assignment Tuesday.

EDGE Analysis

The 29-year-old righty will give up his place on Seattle's 40-man roster for Jhonny Pereda, who was acquired from the Twins on Tuesday. Kowar made 15 regular-season appearances for the Mariners in 2025 and finished the year with a 4.24 ERA and 1.24 WHIP over 17 frames before a right shoulder impingement ended his season in mid-August.

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.

EDGE Analysis

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.

The Mariners optioned Kowar to Triple-A Tacoma on Tuesday.

EDGE Analysis

Kowar had allowed four runs over 2.1 innings covering his last three outings. He'll head to Tacoma for now but could get another opportunity later on this season.

The Mariners recalled Kowar from Triple-A Tacoma on Friday.

EDGE Analysis

Kowar was optioned to Triple-A on Wednesday, but he'll turn around and head back to Seattle to replace the injured Trent Thornton (Achilles). Kowar will likely take on a middle-relief role with the Mariners after posting a 1.54 ERA and 0.86 WHIP through 11.2 innings with the big club this season.
