Tigers activate Jack Flaherty for Astros start, option Enmanuel De Jesus

The Detroit Tigers activated right-hander Jack Flaherty off the injured list on June 28, a move the team made to add another back-end option to its starting rotation as it plays through the stretch leading toward the All-Star break. According to the Tigers’ transaction notice as relayed by MLB Trade Rumors, Flaherty was brought back and will start the team’s game against the Houston Astros on the day of the activation.

Roster management is often as important as the pitching itself this time of year, and the Tigers handled the corresponding spot on the 26-man roster by moving left-hander Enmanuel De Jesus to Triple-A. That option created the space required for Flaherty to return, keeping Detroit’s top-level rotation plans intact while maintaining depth in the organization.

For Flaherty, the activation represents a direct path back to a major-league workload, with Detroit planning to use him immediately rather than in a limited bullpen role. Starting pitchers returning from the injured list typically bring questions about pitch count and overall readiness, but the Tigers’ decision to schedule him for the Astros game suggests the club believes he is prepared to take a regular turn.

The matchup against Houston adds context. The Astros are one of the American League’s more consistent organizations in recent years, and they tend to challenge pitchers with a mix of power and strike-zone discipline. For the Tigers, getting Flaherty back into that kind of environment can serve as a practical checkpoint on whether the rotation’s midseason needs can be met with depth rather than replacement-level options.

De Jesus’s option to Triple-A underscores the volatility that comes with activation moves. Even when a player is healthy and performing well in a bullpen or spot-start capacity, a return from the injured list can quickly reshuffle roles. For Detroit’s left-handed options, the path back to the majors runs through continued strong outings at the Triple-A level and staying ready for the next call-up if another spot opens up.

With the activation now in place, the Tigers will watch how Flaherty handles his first major-league start following the injured list stint. The early indicators will matter not just for that single game versus Houston, but for how Detroit calibrates its next rotation cycle as the season moves toward the midpoint.

What comes next for the pitching staff will likely be defined by follow-through after this initial return. If Flaherty can provide length and stable command in his start, the Tigers can lean on a more typical rotation pattern. If he needs to be managed more tightly, Detroit may have to adjust the sequencing of its other starters and late-inning bullpen workload around him. Either way, this activation gives the Tigers a clearer look at their rotation plans right now.
