The trade deadline doesn’t arrive until Tuesday at 6 p.m., but the Orioles got aggressive today. They found the opportunities to strike and didn’t let them pass.

They latched onto a starter under team control beyond 2024 who didn’t cost one of their top prospects. They strengthened their bullpen and added a plus defender for the outfield.

The total cost was outfielder Austin Hays and minor leaguers Jackson Baumeister, Mac Horvath and Matthew Etzel.

Hays went to the Phillies for reliever Seranthony Domínguez and outfielder Cristian Pache. The Orioles later announced that they acquired Zach Eflin from the Rays.

Eflin will report this weekend. Domínguez and Pache arrived at Camden Yards this afternoon.

With all the speculation that the O’s might be trading some prospects at the trade deadline and amid recent reports via ESPN that the club might be willing to deal Ryan Mountcastle and Cedric Mullins, it was another long-time O's player leaving the club.

Austin Hays, a veteran of 557 games over parts of seven seasons with the Orioles, was dealt to the Philadelphia Phillies.

The return was right-handed reliever Seranthony Domínguez and outfielder Cristian Pache.

Domínguez, 29, provides help for the Baltimore bullpen, which allowed late-game runs the last two days at Miami.

Domínguez is 3-2 with a 4.75 ERA and 1.222 WHIP on the year over 36 innings. Over the last three seasons, since 2022, he has a 3.74 ERA and 1.256 WHIP.

The Orioles made a significant change to their outfield, surrendering one of their longest tenured players, and fortified the bullpen earlier today by consummating their first trade approaching Tuesday’s deadline.

Austin Hays was dealt to the Phillies for reliever Seranthony Domínguez and outfielder Cristian Pache. Minor league pitcher Levi Stoudt was designated for assignment to make room on the 40-man roster.

Hays was a third-round pick in the 2016 draft out of Jacksonville University who made his major league debut the following September and started in last year’s All-Star Game. He’s battled injuries throughout much of his career and played in 63 games this season, slashing .255/.316/.395 with 13 doubles, three home runs and 14 RBIs in 175 plate appearances.

The part-time role was a tough adjustment for Hays, who played in 557 games with the Orioles over parts of seven seasons, but Colton Cowser’s emergence as a regular and the shuffling with Heston Kjerstad and Kyle Stowers limited his opportunities.

The Phillies might platoon Hays with Brandon Marsh before he enters his final year of arbitration eligibility.
