As the Detroit Tigers prepare for the 2026 season, the focus centers on solidifying their pitching rotation, with Jack Flaherty standing out as a key figure despite limited fanfare. With the team addressing past challenges and reinforcing their roster, Flaherty’s role within the Tigers organization becomes crucial to their success going forward.
How the Tigers Have Rebuilt Their Starting Pitcher Lineup
In previous postseasons, the Detroit Tigers faced a shortage of reliable starters, leading to what was dubbed “pitching chaos,” a phrase symbolizing their scramble for effective rotation pieces. Initially, the Tigers signed Drew Anderson from overseas, a move that raised doubts about their commitment to contending. However, the front office and ownership soon changed the narrative by acquiring Framber Valdez and re-signing veteran Justin Verlander. These acquisitions provided the team with two dependable starters who alleviate the pressure on both Cy Young Award winner Tarik Skubal and other members of the rotation.
While much attention has centered around Skubal, Valdez, and Verlander, Jack Flaherty’s contributions warrant strong recognition as part of the Tigers’ pitching foundation.
Jack Flaherty’s Performance Amid a Mixed 2025 Campaign
Flaherty began his tenure with the Tigers ahead of the 2024 season, shaking off concerns about excessive walks and injury history through impressive outings before being traded to the Dodgers midseason. Returning for 2025, he entered with elevated expectations, but inconsistent performances tempered enthusiasm. Notably, two consecutive starts in June where he surrendered seven and eight runs stand out negatively, though these were balanced by three solid outings on either side, allowing just a handful of runs across six innings each.
August similarly displayed fluctuation, with three starts conceding five or more runs, countered by three low-run starts, including a dominant seven-inning performance with nine strikeouts and only three hits allowed. Flaherty’s velocity dipped slightly on his four-seam fastball—down by 0.4 mph—but remained steady or improved on his other pitches. His movement patterns largely mirrored those from 2024, though his slider was less effective.
Perhaps most impactful was a decline in swing-and-miss rates; all three primary pitches recorded lower whiff percentages compared to the previous year, with his fastball falling by seven percent. This suggests command issues, particularly with breaking balls that strayed more over the plate, allowing more contact and diminishing the synergy between fastball and breaking pitches. This lack of precise command contributed to the bouts of inconsistency and occasional “blowup” starts.
Despite these struggles, Flaherty’s advanced metrics offer a more nuanced view: his adjusted expected ERA (3.97) and expected FIP (3.69) were significantly better than his traditional 4.64 ERA, indicating underlying effectiveness that was not fully reflected in raw results.
Factors Supporting a Strong Rebound for Flaherty in 2026
Much of the disappointment around Flaherty last season stemmed from expectations not matching reality. Fans hoped for a return to his earlier dominant form with the Tigers, featuring high strikeout rates and a low-to-mid 3.00s ERA over a full season. However, that level of performance has been rare for Flaherty since 2019.
The new additions of Valdez and Verlander to the Tigers’ rotation reduce the burden on Flaherty to be the team’s primary force, allowing him to focus on consistency as a middle-to-upper rotation starter. This shift lessens mental pressure, which could positively affect his command and overall game management.
Velocity, sometimes a concern in past analyses, appears steady within normal seasonal fluctuations. Flaherty’s initial spring outing showed a fastball average of 93.7 mph, an increase from the previous year, suggesting his ability to challenge hitters remains intact. Enhancing fastball velocity supports improved effectiveness of his breaking pitches, particularly his knuckle curve, which is critical for generating swings and misses.
Last season’s subtle drop in whiff rate on the knuckle curve was offset by a rise in hard contact allowed, attributed primarily to pitch location issues such as leaving too many balls in the lower portion of the strike zone rather than painting the edges. The Tigers’ coaching staff has previously helped Flaherty adjust such flaws, indicating similar improvements are possible as he continues working with the team.
Despite an uneven campaign, Flaherty achieved 10 quality starts in 2025, just one fewer than in 2024, demonstrating flashes of the high-caliber pitcher he can be. His pitch movement and velocity have not dramatically changed between seasons, making command and pitch placement the key areas for unlocking his full potential.
Assessing Flaherty’s Role and Outlook Moving Forward
Jack Flaherty’s recent seasons show a pitcher resilient enough to consistently throw over 160 innings and exceed 185 strikeouts even when not at peak form. He has not experienced severe injury setbacks or steep declines in key performance indicators, distancing him from the risk factors that often truncate promising careers.
Although Flaherty may not fit the profile of an unquestioned frontline ace, he possesses the attributes of a reliable, high-end middle rotation arm who can stabilize the Tigers’ pitching staff. With command improvements within reach, and a proven ability to overcome hurdles, expecting Flaherty to be a pivotal piece in Detroit’s rotation for 2026 is reasonable.
Given the Tigers’ demonstrated capacity to address flaws in their pitchers’ mechanics and approach, there is little to suggest that Flaherty cannot overcome recent issues. His sustained strong underlying metrics and demonstrable skill set make him an underrated, yet essential, part of the Tigers’ rotation strategy as the team aims for greater success.
