The Baltimore Orioles have been widely expected to be major sellers at the 2025 trade deadline.

While the team fully expects to try and compete next season, they have several pending free agents that still make sense to move, especially with the Orioles not likely to compete this season and the trade market looking very shallow at the moment. On Tuesday, Baltimore’s plan took further shape.

The position that the Orioles have the most tradable depth, without question, is in bullpen arms, which is a popular demographic this time of year.

After trading Gregory Soto a few days ago, Baltimore is continuing to try and capitalize on their depth and position by striking a trade with the Blue Jays to send Seranthony Dominguez in exchange for pitching prospect Juaron Watts-Brown.

Orioles trade Seranthony Dominguez to the Blue Jays for intriguing pitching prospect Juaron Watts-Brown

Being a pending free agent that is making real money ($8 million) this season made Dominguez a prime candidate to get moved from the beginning. In 43 appearances this season, Dominguez has posted a 3.24 ERA with 54 strikeouts in 41.2 innings of work.

In exchange, the Orioles are getting a pretty intriguing starting pitching prospect, which is great news since rotation arms are not an organizational strength at the moment. Watts-Brown was a third-round pick in the 2023 MLB Draft and has already pitched his way to Double-A thanks to a plus slider and big-time strikeout numbers. Orioles fans should expect Watts-Brown to move quickly and potentially play a role in 2026.

The return for Dominguez was never going to be massive as a rental, non-closing reliever, but Baltimore was smart to send over some cash in the deal to make sure they got an impact pitching prospect in the deal. Assuming this is a trend, the Orioles could end up in a really strong position post-deadline with a restocked farm system and the loss of few (if any) long-term assets.
