The Baltimore Orioles have been one of the biggest disappointments this season, posting a 45-58 record after the all-star break and are currently trading away some of their players with expiring deals.
Gregory Soto was the first to go, with the reliever being sent to the New York Mets for a pair of prospects. Others like Tomoyuki Sugano, Ryan O’Hearn, and Cedric Mullins are likely also on the trade block, as well as fellow reliever Seranthony Dominguez, a potential target for the Blue Jays at the upcoming trade deadline.
Dominguez is a 6-foot-1 right-hander who has spent seven years in the big leagues. Originally signed by the Phillies as an international free agent, Dominiguez made his big league debut in 2018 and spent parts of six seasons in the NL East before being moved to the Baltimore Orioles at the 2024 trade deadline.
This season, Dominguez has found himself in 42 relief opportunities and has posted a 3.32 ERA and a 3.53 FIP through 40 2/3 innings. He has always been a strong strikeout type arm, and owns an 11.7 K/9 this season. While his arm has been a bit wild at times over the years, Dominguez is finding a new high with his free passes, amassing a 5.3 BB/9 and 24 walks this season, which has seen his WHIP rise to 1.352 so far this season. After a solid June showing (12 outings, six hits, zero earned runs), the Dominican product owns a 4.26 ERA through seven outings in July, allowing nine hits and three earned runs through 6 1/3 innings.

Working with a five-pitch mix, Dominguez leads with his four-seam fastball and mixes in a sweeper, split-finger, sinker, and curveball as well. His best pitch this season has been the split-finger, sitting at a +3 pitching run value, with his sweeper being the other pitch in positive territory (+2) while his fastball sits at -2, with opponents owning a .236 xBA and a .380 xwOBA on the offering. Even though his fastball can hit the high 90s, he has struggled to generate strong putaway numbers on the pitch, sitting at a 21.2% mark.
Before the 2023 season, Dominguez signed a two-year deal worth $7.25 million with the Phillies that included a club option for 2025, which the Orioles exercised at $8 million. Dominguez will be a free agent this winter, so any team that acquires the right-hander is looking at a rental situation.
The Toronto Blue Jays’ bullpen has struggled to stay healthy this season, and adding a pitcher like Dominguez raises the floor, even with the walking concerns mixed in. Ryan Burr, Yimi Garcia, Nick Sandlin, and Paxton Schultz are all on the IL.
Adding some depth with an arm like Dominguez, who has experience pitching late game or high-pressure situations, makes the Jays a better team and likely at a cheaper price point compared to some other names on the trade block this summer, given his expiring deal.
The hurdle will be whether the Blue Jays and Orioles can complete an intradivision deal. It’s not impossible, evidenced by the Jays moving Danny Jansen to the Boston Red Sox last summer, but helping a division rival for their postseason aspirations can rub a fan base the wrong way, especially since the two sides will square off later this month at the trade deadline. Having him hop from the home clubhouse to the visitors clubhouse may make for a fun narrative, though.
Dominguez makes sense for Toronto if the two sides can work out a deal, and if the Orioles’ expectations are around what they got for Soto in the Mets deal, the Jays have the prospect capital to complete a deal of this nature and save some players for other potential deals as well.
