2025 Fantasy Outlook
Flaherty had an interesting 2024 season after languishing in prior seasons attempting to recover what he last was in 2019 with the Cardinals. He may never get back to that level of success, but he came closer in 2024 than in any other season since his peak, even with the midseason change of employment. Flaherty came into the season working on his pitch shape and repertoire, and it showed in his success. The actual outcomes of his four-seamers in 2024 (.245 BA) matched the expected outcomes the pitch failed to realize in 2023 (.247 xBA), but the slider is where the success story truly lies. Flaherty had both a cutter and slider in 2023, and neither was an effective pitch by actual nor expected results. Flaherty scrapped the cutter and worked on the slider, and the work paid off. The league average against the pitch dropped from .339 to .222, while the pitch's whiff rate jumped from 26.5 to 36.3 percent. The postseason version of Flaherty reminds us of his inconsistent track record, and the last time he worked this much in a season, the subsequent season was disastrous. The 2024 season was a much-needed career recovery for Flaherty, but the path forward is anything but certain given his track record. Read Past Outlooks
Signed a one-year, $25 million contract with the Tigers in February of 2025. Contract includes $10 million player option for 2026. Contract includes $10 million escalator for 2026 salary with 15 games started in 2025.
Takes loss in Game 3
Flaherty took the loss in Game 3 of the ALDS against Seattle on Tuesday after giving up four runs (three earned) on four hits and three walks while striking out six batters across 3.1 innings.
Analysis
The 29-year-old righty allowed just one man to reach base through two innings following a three-hour rain delay, but things took a turn at the start of the third frame after consecutive hits from Victor Robles, J.P. Crawford and Randy Arozarena allowed the Mariners to take a 2-0 lead. Flaherty came back out for the fourth frame but was quickly pulled after allowing a leadoff homer to Eugenio Suarez and walking Victor Robles, who eventually came around to score. The Tigers now find themselves on the brink of elimination, and Flaherty likely won't be available to pitch in relief for the rest of the series after needing 76 pitches to collect 10 outs Tuesday.

The good news for Flaherty is that he was healthy enough to make 29 appearances (27 starts) and throw 144.1 innings in 2023. That's no small feat for a guy who totaled 26 appearances (23 starts) and 114.1 frames over the previous two seasons combined. The bad news is he never resembled the guy who once looked like a budding ace. To give you an idea of how much Flaherty's stuff has backed up, note that he gave up 27 more hits in 2023 than he did during his stellar 2019 season, and he did so in 52 fewer innings. Flaherty's control has also become a problem, with his 10.2 percent walk rate representing the ninth-highest mark among 76 pitchers with at least 140 innings. The Orioles were intrigued enough by the righty to trade for him at the deadline, but he held a 6.75 ERA for them and was demoted to the bullpen. Detroit gave Flaherty a one-year, $14 million contract over the winter, and the righty will get to pitch in a favorable home park and work with up-and-coming pitching coach Chris Fetter. Flaherty is still young enough (28) to rediscover something, but he'll need to prove it before fantasy managers can trust him again.

Latest Fantasy Rumors
Undecided on future
Flaherty is undecided on whether to return to Detroit for the 2026 season, according to Evan Woodbery of MLive.com, who said that "it would be a surprise" to see Flaherty pick up his player option for the upcoming campaign.
Analysis
Flaherty signed a two-year, $35 million contract with the Tigers before the start of the 2025 season, but he increased that guarantee by reaching the 15-start threshold and escalating his 2026 player option from $10 million to $20 million. If Flaherty feels he can get more than $20 million in the open market, he could reject the option and enter free agency for a third consecutive offseason. Flaherty had a 4.64 ERA across 161 innings in the 2025 regular season for Detroit.
