Detroit Tigers' Casey Mize lands on injured list; Beau Brieske returns

Detroit Tigers Place Casey Mize on Injured List and Recall Beau Brieske The Detroit Tigers placed right-handed pitcher Casey Mize on the 15-day injured list on May 29, retroactive to May 28, ahead of their series against the Chicago White Sox at Rate Field. The club recalled right-handed reliever Beau Brieske from Triple-A Toledo to fill the roster spot. The transaction was confirmed by the team prior to the May 29 contest. This roster adjustment comes as the Tigers manage pitching depth during their American League Central schedule. Mize, 28, had posted a 3-4 record with a 4.15 ERA across nine appearances and 43 1/3 innings this season before the move.

Transaction Details

Detroit Tigers officials announced the placement through the team’s media relations department on May 29. The 15-day injured list allows Mize to miss a minimum of 15 games while the club evaluates his condition. Brieske, who had been optioned earlier in May, rejoined the active roster and was available for the White Sox series. No specific injury details were released in the initial club statement. Team medical staff will continue to monitor Mize, with updates provided as permitted under league rules. The timing aligns with standard roster procedures that give clubs flexibility to address short-term absences without immediate long-term decisions.

Player Backgrounds

Casey Mize was selected first overall by the Tigers in the 2018 MLB Draft out of Auburn University. He made his major-league debut in 2020 and recorded a 3.71 ERA across 71 appearances through the 2024 season. Mize underwent Tommy John surgery in 2022 and returned to the rotation in 2024. His 2025 campaign included starts against several American League Central opponents before the current placement. Beau Brieske, drafted by Detroit in the 27th round of the 2019 draft out of Colorado State University–Pueblo, has appeared in 48 major-league games since 2022, primarily in relief. He posted a 4.82 ERA in 18 2/3 innings during his most recent major-league stint before the May recall. His return provides the Tigers with additional bullpen options during the current series.

Team Context

The Tigers’ pitching staff entered the May 29 series with a 3.92 ERA, ranking eighth in the American League. Manager A.J. Hinch addressed roster decisions in pregame remarks, noting the need for adjustments to maintain competitive balance. Such moves reflect ongoing efforts to balance development and performance across the rotation and relief corps. These roster changes occur against the backdrop of a season in which the Tigers have relied on a mix of established starters and recalled arms. The placement of Mize shifts immediate responsibilities to other members of the pitching group while Brieske integrates back into game situations.

Outlook for the Roster

The Tigers will continue to monitor Mize’s status under league guidelines, with further roster decisions likely to follow based on medical evaluations and performance needs. Brieske’s presence on the active roster adds depth for upcoming games in the White Sox series and beyond. Additional transactions remain possible as the club navigates the remainder of the schedule.
