Orioles juggle 40-man roster, activating Dean Kremer and recalling Cameron Weston

The Baltimore Orioles made multiple roster moves on Wednesday, reshaping both their active pitching group and their 40-man roster picture as the season moves deeper. The central transaction was the activation of right-hander Dean Kremer from the 60-day injured list, a move that aligns with his immediate return to the starting rotation.

According to MLB Trade Rumors, Baltimore reinstated Kremer and scheduled him to start against the Chicago White Sox within hours of the announcement. For an Orioles team that often relies on stability at the back of its rotation, getting a pitcher back from the 60-day IL can change how the staff is managed over subsequent turns, particularly if Baltimore is balancing innings limits and bullpen workload.

The Orioles also needed a roster opening, and they addressed that by designating minor league catcher Dom Keegan for assignment. That step is typically used to create room on the 40-man roster, and it indicates Baltimore is actively weighing its organizational catchers while also prioritizing other players’ inclusion at the major league level.

On the pitching depth side, Baltimore recalled right-hander Cameron Weston from Triple-A Norfolk. The move gives the Orioles another arm available for immediate major-league use, whether as a bullpen option or as a spot starter/late-inning complement, depending on how manager decision-making unfolds in the next set of games.

Along with the additions, the Orioles also made corresponding option moves. MLB Trade Rumors reported that Baltimore optioned top prospect Trey Gibson and left-hander Josh Walker, continuing a pattern common for contenders and playoff hopefuls: promoting players who match immediate roster needs while preserving longer-term development plans in the minors.

These transactions collectively point to a team trying to maintain flexibility without overcommitting spots on the 40-man roster. Designating a player for assignment gives the organization time to decide whether that catcher will remain within the organization’s major-league options, be traded, or be claimed by another club.

For fans and baseball operations, the immediate watch item is how Kremer looks in his first start back and how the Orioles’ rotation and bullpen are managed after his return. The second watch item is whether the Weston recall becomes a short-term lift or turns into a more durable role, and what the Keegan designation could mean if another team takes an interest.
