Orioles Trade Seranthony Dominguez To Blue Jays

The Blue Jays and Orioles executed a bit of business between games of their doubleheader today, as Baltimore traded right-hander Seranthony Dominguez and cash to the Toronto in exchange for minor league righty Juaron Watts-Brown. Both clubs have announced the swap. The Jays designated veteran reliever Chad Green for assignment to open 40-man and 26-man roster spots for their new acquisition.

Dominguez, 30, is earning $8MM in his final season of club control. He’s spent the past year in Baltimore after coming over from the Phillies at the 2024 trade deadline. The 6’1″, 225-pound righty has been among the Orioles’ top setup options this season, pitching 41 2/3 innings of 3.24 ERA ball with an excellent 30.9% strikeout rate but also a troubling 13.7% walk rate. Command has been a problem for the hard-throwing Dominguez at times in the past, but never quite to this extent.

Even with the glut of free passes, Dominguez has still enjoyed a strong year. This year’s strikeout rate is the second-highest of his career (second to only his rookie season), as is his 14.3% swinging-strike rate. He’s sitting 97.7 mph with his four-seamer and 97.9 mph with his sinker, per Statcast, pairing those blistering primary offerings with a pair of newly implemented secondary weapons: a splitter averaging 87.4 mph and a more seldom-used curveball that’s sitting 83.7 mph.

Dominguez has picked up 13 holds and a pair of saves. He’s been charged with three blown saves on the season. Outside of closer Felix Bautista, no reliever in the Baltimore bullpen has been used more frequently in high-leverage situations. He’s no stranger to protecting late leads, either, evidenced by the 40 saves and 71 holds he’s tallied in 298 major league appearances dating back to his 2018 debut in Philadelphia.

Toronto’s bullpen entered play today tied for seventh in the majors with a collective 3.72 ERA — although that was before serving up a whopping 12 runs to the Orioles in the first game of today’s twin bill. (Two of those runs were yielded by backup catcher Ali Sanchez pitching in mop-up duty.) They’ve gotten terrific work out of Yariel Rodriguez, Brendon Little and Braydon Fisher, in particular.

Offseason signee Jeff Hoffman has a 4.73 ERA, though that’s skewed a bit by a five-run meltdown back in May. He’s pitched to a flat 3.00 ERA with a 33.8% strikeout rate and 5.6% walk rate in 18 innings dating back to June 1. Fellow veteran Yimi Garcia, who re-signed as a free agent with the Jays this winter after being traded to the Mariners last July, missed more than a month with a shoulder impingement and then was placed back on the IL day due to an ankle sprain just three days after returning. He’s still on the shelf but has posted a 3.86 ERA in 21 innings when healthy.

The Jays are eyeing a variety of upgrades as they look to keep their spot atop the standings in the American League East. They’ve been in the hunt for bullpen upgrades — and still are even after acquiring Dominguez, per Mark Feinsand of MLB.com — in addition to rotation arms like Dylan Cease and prominent bats like Steven Kwan (though Kwan, in particular, is a long shot to change hands). In an effort to obtain upgrades of that nature, they’ve been willing to listen to trade offers on some controllable young big leaguers who’ve gotten their feet wet in the majors already, though that didn’t prove necessary with regard to Dominguez.

Dominguez will net the Orioles the 23-year-old Watts-Brown, whom the Blue Jays selected with their third-round pick back in 2023. The Oklahoma State product has spent the season in the rotation at High-A and Double-A, logging a combined 3.54 ERA with a 30.5% strikeout rate and 10.1% walk rate in 89 innings. He ranked 14th among Jays prospects, per Baseball America’s most recent midseason update of their system.

Listed at 6’3″ and 190 pounds, Watts-Brown sits 92-94 mph with his four-seamer and can run it up a couple ticks higher when he needs to reach back for more. Scouting reports at BA, MLB.com and FanGraphs all laud the lanky right-hander’s slider and curveball as plus pitches, but command troubles and a lack of missed bats with his heater have led to some thought that he might be better suited for a relief role down the road. The Jays have continued to develop him as a starter, and that’ll presumably be the case as well for an Orioles club that is quite thin on upper-level pitching.

Watts-Brown walked an untenable 13.2% of hitters in 2024 and, after notching a much-improved 7.7% walk rate in High-A to begin the season, is back up to an 11.8% walk rate in 11 Double-A starts. He’s also plunked four hitters in 51 innings there. Watts-Brown will need to further refine his command to thrive as a starter, but his frame and four-pitch arsenal lend themselves well to rotation work if he can scale back on the free passes. That he’s already in Double-A suggests a potential 2026 debut for the former third-round pick if things go well.

Dominguez is the third reliever shipped out by a disappointing Baltimore club this month. The O’s sent Bryan Baker to the Rays prior to the All-Star break and traded Gregory Soto to the Mets last week. Dominguez and Soto were obvious trade candidates, given their impending free agency on a team that has fallen well shy of expectations. Other O’s veterans who are set to hit the market at season’s end (e.g. Ryan O’Hearn, Cedric Mullins, Zach Eflin, Charlie Morton) are likely to follow.

Ben Nicholson-Smith and Shi Davidi of Sportsnet first reported the trade.
