In between Games 1 and 2 of the teams’ doubleheader in Baltimore on Tuesday, the Toronto Blue Jays acquired right-handed reliever Seranthony Dominguez from the Orioles, according to multiple reports.
The Orioles will receive right-handed pitching prospect Juaron Watts-Brown to complete the trade, Sportsnet and ESPN reported.
Dominguez, 30, last pitched Sunday, when the Orioles defeated the visiting Colorado Rockies 5-1. He did not appear in the first game of Tuesday’s twin bill, a 16-4 Baltimore rout of Toronto.
The Blue Jays are in first place in the American League East and made the deal with their division rival for an experienced bullpen arm.
In 298 career games with the Philadelphia Phillies (2018-24) and Orioles (2024-25), Dominguez has gone 21-22 with 40 saves, a 3.54 ERA and 335 strikeouts across 285 innings. He did not play in 2020 due to injury.
In 2025, Dominguez has gone 2-3 with two saves and a 3.24 ERA in 43 appearances for the Orioles. He’s struck out 54 batters for a rate of 11.7 strikeouts per nine innings.
Watts-Brown, 23, has split this season between Double-A New Hampshire and High-A Vancouver. He has gone 2-5 with a 3.54 ERA in 19 starts. MLB Pipeline ranked Watts-Brown as Toronto’s No. 10 prospect.
