Orioles Claim Shawn Dubin, Designate Matt Bowman For Assignment

The Orioles announced that they have claimed right-hander Shawn Dubin off waivers. The Astros designated him for assignment earlier this week. The O’s also announced that righty Kyle Bradish has been reinstated from the 60-day injured list, a move which was previously reported. To open 40-man spots for those two, the O’s transferred righty Scott Blewett to the 60-day injured list and designated righty Matt Bowman for assignment. Bowman’s DFA opens an active roster spot for Bradish. Dubin is out of options and will also need an active roster spot once he reports to the club.

Dubin, 29, isn’t having his best season but has shown promise in the past. He came into the year with 54 1/3 big league innings and a 4.64 earned run average. His 11.6% walk rate was a bit high but he had struck out 24.1% of batters faced and kept balls in play on the ground at a 45.5% clip.

Here in 2025, he has spent time on the IL due to shoulder inflammation and a forearm strain. Around those IL stints, he tossed 25 2/3 innings for the Astros with a 5.61 ERA. His 46.9% ground ball rate was still good and he dropped his walk rate to 7.2% but his strikeout rate also fell to 18.9%. Since he is out of options, he got nudged off Houston’s roster and onto the waiver wire.

He’s a sensible flier for the O’s. They are playing out the string on a lost season. Their bullpen has been stripped down a lot this year. They traded Seranthony Domínguez, Gregory Soto and Andrew Kittredge ahead of the deadline. Closer Félix Bautista recently underwent shoulder surgery and will be out of action well into 2026. That gives them a lot of roles to fill on the 2026 team.

They can use the remainder of this season to take chances on guys like Dubin to see what happens. He is out of options but could be a long-term piece if he bounces back. His service time is between one and two years, meaning he could be controlled for five seasons beyond this one if he continues to hold onto a roster spot. It’s also possible the O’s try to run him through waivers in the future in order to keep him as a non-roster depth piece.

As for Blewett, he was acquired from Atlanta in a June cash deal. He was placed on the 15-day IL July 13th due to elbow discomfort. This transfer is backdated to that initial IL placement, so he’ll be eligible for reinstatement in a couple of weeks. That gives him a window to pitch again this season but it’s unclear if that’s possible from a health perspective.

This was Bowman’s fourth stint of the season with the Orioles. He appeared in one game, pitching 1 1/3 innings but allowing a pair of runs. That ballooned his season-long earned run average to an ugly 6.20. Bowman has been solid in Triple-A Norfolk, tossing 26 1/3 innings for the Tides and posting a 4.10 ERA. He’s set down 21.8% of his opponents there on strikes and notched a 5.5% walk rate.

Bowman will be placed on outright waivers or release waivers within the next few days. He’s cleared waivers at multiple points this season and accepted an outright assignment to Norfolk each time, so it seems there’s a strong chance the O’s will hang onto him as a depth arm for the final month or so of the regular season.
