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

Sharp in second spring outing
Flaherty tossed four scoreless innings in Tuesday's Grapefruit League game against Atlanta. He walked two and struck out three.
ANALYSIS
Flaherty was just about flawless in his second spring outing. The Tigers gave him more than 10 days off between Grapefruit League starts, so it appears that the team is taking it easy on the righty before the season begins. Flaherty tossed a total of 162 innings for the Tigers and Dodgers last regular season, then saw another 22 innings in the postseason for Los Angeles as he helped lead the team to a World Series title. The 29-year-old will slot in behind staff ace Tarik Skubal to begin 2025.

Dive into the MLB picks today as Michael Rathburn analyzes Friday's slate and lines up his three best bets to target for the action.

FanDuel’s Friday picks include Freddie Freeman who’s a relatively inexpensive Dodger option going against Jack Flaherty at home.

With supposed paragon of durability George Kirby opening the year on the injured list, it's time to ask whether or not we really have any idea about which pitchers are injury-prone.

Tarik Skubal's Cy Young defense gets off to a tough start this weekend as he takes on the defending champions in Dodger Stadium. Where does he rank in Todd Zola's first pitcher rankings of the year?

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

Might be option for San Diego
The Padres would consider targeting Flaherty if they trade Dylan Cease or Michael King, Jon Heyman of the New York Post reports.
ANALYSIS
Nick Pivetta would also be an option for San Diego if either Cease or King is dealt. Flaherty is reportedly open to the idea of doing a shorter contract with a higher average annual value, as he has not been getting the sizable, long-term offers he had been hoping for. The 29-year-old posted a 3.17 ERA, 1.07 WHIP and 194:38 K:BB across 162 regular-season innings in 2024.
