Trey Gibson Designated For Assignment Amid Orioles Roster Shuffle

The Orioles designated for assignment Trey Gibson’s roster spot in a Monday bullpen shuffle, then optioned him to Triple-A Sacramento before their game against the Yankees. The move also brought left-hander Josh Walker onto the roster and used Heston Kjerstad’s injured-list transfer to clear space.

Trey Gibson and Josh Walker

Gibson was the pitcher moved out after tossing two innings on Friday. Josh Walker had his contract selected from Triple-A Norfolk as the corresponding move, giving Baltimore a left-handed arm for the group heading into Monday night.

The timing points to a quick reset rather than a long wait. Baltimore made the move at 6:20 p.m. EDT on May 11, with the roster adjustment arriving before the Yankees game and leaving Gibson in Triple-A Sacramento after a short stay on the major league side.

Heston Kjerstad on 60-day IL

Heston Kjerstad’s right hamstring strain sent him to the 60-day injured list, and that transfer opened the 40-man roster spot Walker needed. Kjerstad’s move did not change the bullpen plan by itself, but it made the roster math work for Baltimore’s transaction.

For Orioles fans tracking the bullpen picture, the important part is the sequence: Gibson was optioned, Walker was added, and Kjerstad moved to the 60-day IL to create room. That is the full roster chain for Monday, with Baltimore entering the Yankees game having reshaped both its active pitching staff and its 40-man setup.

Baltimore before Yankees

The practical effect is immediate for Gibson and Walker. Gibson heads back to Triple-A Sacramento after two innings on Friday, while Walker joins the Orioles from Triple-A Norfolk as the club leans into a bullpen move on the eve of a game against New York.
