The Detroit Tigers are making proactive roster adjustments by recalling right-handed pitcher Keider Montero and sending left-handed pitcher Bailey Horn to Triple-A Toledo. Montero is stepping in to support a fatigued bullpen as the Tigers manage injuries among their pitchers. Despite frequent moving between the major league and minor league, Montero has become a key player on the team, ranking fourth in innings pitched. However, his strikeout rate remains low compared to his workload, presenting a challenge in his effectiveness on the mound.

With the Tigers already dealing with injuries to key starters including Jackson Jobe, who is out for the season with Tommy John surgery, and Sawyer Gipson-Long on the injured list, Montero’s role is crucial. The team is optimistic about the potential return of José Urquidy and Alex Lange in the near future, which could further impact Montero's usage and the overall strength of the pitching rotation.

The Detroit Tigers are facing challenges in their bullpen as reliever John Brebbia has been placed on the 15-day injured list due to a right triceps strain. This marks the second reliever the team has put on the IL within two days, following Beau Brieske's similar fate. Brebbia, who has struggled with his recent performance, threw 31 pitches in his last outing against Kansas City before succumbing to injury.

In a strategic move, the Tigers have called up Bailey Horn from Triple-A Toledo to fill the gap left by Brebbia. Horn has had a rocky start in the minors, posting a 6.48 ERA over 8⅓ innings this season. Meanwhile, manager A.J. Hinch expressed concerns over Brebbia's inconsistency on the mound, contrasting it with his earlier efficient performances. The Tigers will need to adapt quickly as they navigate this difficult patch in their season.
