Jack Flaherty is back. The Detroit Tigers right-hander returned from the injured list on September 27, 2026, and is now on the active roster as the Tigers navigate the postseason. The return of a starting pitcher with Flaherty's experience is a significant roster development for Detroit, giving the club an additional arm available at one of the highest-stakes stretches of the year.
What We Know About Flaherty's Return
Flaherty's return was confirmed as of Monday, September 28, 2026. He is listed as active and eligible to pitch. No additional details about the nature of the injury or how he was used immediately upon activation are available at this time.
Where Flaherty Stands Coming In
Context matters here. In 2025, Flaherty made 31 starts and logged 161 innings, posting a 4.64 ERA with a 1.28 WHIP and 188 strikeouts against 59 walks — a strikeout-to-walk ratio of 3.19. He struck out 10.51 batters per nine innings, showing he can miss bats at a high level. The flip side: an 8-15 record and a 1.29 home runs per nine innings rate are numbers that earned genuine scrutiny. He is not returning on a hot streak — his 2025 numbers reflect a pitcher who can be dominant in stretches and costly in others.
Why It Matters in the Postseason
Roster depth in October is everything. Getting a starting pitcher back onto an active postseason roster — regardless of recent form — expands the options available to Tigers manager. Whether Flaherty slots into a starting role or is deployed out of the bullpen in longer relief, his availability gives Detroit flexibility it did not have while he was sidelined. The Tigers will need every healthy arm they can get.
