Athletics vs Orioles

It's a big step for the 31-year-old, though there remains no timetable for his return to the active roster. Rooker has been shelved for the past week-and-a-half with a right oblique strain and could need a few rehab games before returning to the Athletics' lineup.

Kittredge's assignment was paused Tuesday when he went on paternity leave, but he's now back with the Tides, continuing to work his way back from the right shoulder inflammation that sent him to the injured list at the beginning of the year. The 36-year-old has already made three appearances at Triple-A, allowing one earned run on three hits and a walk while striking out five batters through 2.2 innings.

Selby's move to the 60-day IL will ensure he remains sidelined until at least late May and open up a spot on the 40-man roster for Jackson Kowar, who was acquired in a trade with the Twins on Saturday. Selby isn't reportedly dealing with any structural damage, which increases the likelihood that he returns to the Orioles' bullpen after a minimum-length IL stint.

In a corresponding move, the Orioles recalled Brandon Young from Triple-A Norfolk, who will take over for Kremer's starts while he is out. Kremer will miss at least two starts if he is able to return right after the 15-day window.

Enns landed on the 15-day injured list April 6 due to a left foot infection. He has recovered enough to go on a rehab assignment and shouldn't need more than a couple of outings before returning to the majors. Enns appeared in three games prior to his IL stint, allowing two runs on two hits and five walks while striking out seven across 4.1 innings.

Kjerstad suffered a right hamstring strain during a March 19 Grapefruit League game, resulting in a stay on the injured list to open the season. The 27-year-old outfielder lacks a concrete timeline for a return to the field, though he'll likely need a minor-league rehab assignment before becoming an option to rejoin the Orioles.

Akin has been shelved all season with a left groin strain but has been cleared to try things out in game action. The lefty suffered the injury late in spring training and doesn't need to rebuild much stamina as a reliever, so Akin could require only a couple rehab appearances if he looks and feels good.

Mountcastle was diagnosed with a fractured fourth metacarpal in his left foot following his exit from Saturday's game against the Giants. His placement on the 60-day IL means the earliest he can return to major-league action is mid-to-late June, though it wouldn't be surprising to see Mountcastle on the shelf until the All-Star break in mid-July. With Mountcastle sidelined for an extended period of time, the Orioles acquired Christian Encarnacion-Strand from the Reds and assigned him to Triple-A Norfolk.

O'Neill is slowly easing back into activities as he works his way back from a concussion. He hasn't played in a game in nearly two weeks, so there's a good chance O'Neill will need a short rehab assignment before rejoining the Orioles' active roster.

Though the Orioles are still labeling Hiraldo's shoulder injury as inflammation, the team's decision to move him from the 15-day injured list to the 60-day IL last week would seem to suggest that he could be dealing with something more significant. After he receives a second opinion from Dr. ElAttrache, Hiraldo will decide on a treatment plan for his injury. The righty reliever made just three appearances for Baltimore before landing on the shelf.

The Orioles moved Eflin to the 60-day injured list Tuesday after he received a second opinion on his injured elbow, and he'll now be out until midway through the 2027 campaign after going under the knife. The 32-year-old righty will finish 2026 having made just 15 starts over the past two seasons, during which he's posted a 5.76 ERA and 1.43 WHIP over 75 innings.

An X-ray confirmed the thumb fracture, which Vazquez suffered when he was hit by a pitch in Sunday's game against the Nationals. Vazquez also required stitches to seal a wound on his hand. A timeline for Vazquez's return will likely depend on whether or not he requires surgery, but regardless, the thumb injury removes the 26-year-old from consideration for a reserve infield role on the Orioles' Opening Day roster. Vazquez is expected to open the season on Triple-A Norfolk's injured list.

The right-hander continues to get the job done as the Orioles' closer, and Helsley has converted all six of his save chances to begin the season. Last year's homer issues also have yet to resurface -- after he served up nine long balls over 56 innings in 2025 between the Cardinals and Mets, leading to a 4.50 ERA, Helsley has yet to be taken deep over 8.1 innings in 2026 while producing a 2.16 ERA.
