2024 Fantasy Outlook
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. Read Past Outlooks

October 31, 2024
Flaherty was tagged four runs on four hits and one walk over just 1.1 innings Wednesday against the Yankees in Game 5 of the World Series. He struck out one and didn't factor in the decision.
ANALYSIS
It's not clear whether the hamstring issue which bothered Flaherty toward the end of his Game 1 start was an issue Wednesday, but he didn't have anything working for him in this one. A one-out walk to Juan Soto in the first inning was followed by back-to-back homers from Aaron Judge and Jazz Chisholm, and the Yankees tacked on another run with one out in the second before Flaherty was pulled. The early hook by Dodgers manager Dave Roberts proved to be a wise move, as the bullpen held the Yankees to just two runs over the next 7.2 frames while the offense did enough to pull out the victory. Flaherty had an uneven postseason, mixing in some stellar efforts with some clunkers, and he ultimately finished with a 7.36 ERA and 15:9 K:BB over 22 innings covering five starts.

After finishing the 2021 season seemingly healthy, Flaherty experienced shoulder soreness in spring training. He received a PRP injection to help combat the inflammation and Flaherty was shut down for a bit before ramping up with bullpen sessions. Flaherty made his debut on June 15 but mustered only three short appearances before a recurrence of the shoulder strain, sending him to the 60-day IL. Flaherty returned in September for five starts, posting a 4.00 ERA and 1.48 WHIP in 27 innings with 26 punch outs. However, control was an issue with 13 walks. Making it back and throwing all his pitches with normal velocity is encouraging, but including rehab, Flaherty has only logged 190.2 innings over the past three years. Even if healthy and effective, Flaherty's workload will likely be monitored. The smart approach is drafting Flaherty as a luxury, but chances are someone will pay for the potential.
Flaherty was supposed to be the anchor to the Cardinals' rotation, yet two separate injuries limited his season to fewer than 80 innings. He began the season extremely well, going 8-1 in his first 11 starts with a 2.90 ERA and 1.03 WHIP while striking out 26% of the batters he faced. He hit the IL for the first time at the end of May after straining his oblique while (unnecessarily) batting, and did not return to the mound until mid-August when he made three more starts before leaving in the last of those three starts with a right shoulder strain. Flaherty came back late in the season to work in relief, but there is no way to sugarcoat how disappointing the season was after such a terrific start. That disappointment carries over into 2022, as a small tear in Flaherty's right shoulder will sideline him for the start of the season. He received a PRP injection and is shut down from throwing for two weeks, but it's unclear exactly how much time he'll actually miss. Flaherty was expected to be a high-risk/high-reward pitching option for fantasy managers, and that risk is now even higher as his injury issues continue in 2022.
The small samples that come with a 60-game season were always going to lead to some disappointing years from top players. Flaherty was most certainly among that group. The large number of doubleheaders the Cardinals were forced to play due to their COVID-related shutdown meant the young right-hander was able to make just nine starts, and he struggled to a disappointing 4.91 ERA in those outings. There are plenty of reasons not to be too worried about his future. His strikeout rate dropped slightly from 29.9% to 28.8%, his walk rate rose from 7.1% to 9.4% and his groundball rate increased from 39.5% to 42.6% -- these are all marginal differences, suggesting he was essentially the same pitcher in terms of skills. One awful start can completely tank a player's ERA in such a short season, and Flaherty's would sit at a much-better 3.13 if not for a nine-run blowup against the Brewers in mid-September.
While 2018 was the breakout for Flaherty's delicious slider, 2019 was the breakout season for Flaherty as a pitcher. That seems silly to say when we look back at the midpoint of the season and find Flaherty 4-5 with a 4.90 ERA in his first 17 starts, but it was. At that time, Flaherty was getting the strikeouts, but 1.9 homers per nine innings limited his success. Flaherty changed his tune over his final 16 starts, going 7-3 with a 0.93 ERA and allowing six homers over his final 106.1 innings of work. He was simply masterful down the stretch for the Cardinals, holding opponents to a .139 batting average over those 16 starts. The real Flaherty lies somewhere in between those two groupings of stats. It is worth noting he has thrown over 400 innings the past two seasons, including 213.1 IP in 2019 when you include postseason work. That, plus the slider usage, is something to consider before going all-in.
The year didn't end on a positive note, with Flaherty posting a 5.34 ERA in September, but the overall body of work was stellar, especially for a 22-year-old taking his first real spin through the major leagues. Flaherty's fastball/slider combo is already one of the best in the game, and he can also change speeds although the changeup was a clear fourth offering behind the heater, slider and curve. He used that arsenal to strike batters out at a 29.6% clip, which was a top-10 mark among all pitchers with at least 150 innings. He shot himself in the foot occasionally with walks (3.5 BB/9) and homers (1.19 HR/9), but even marginal improvement to his 57.2% first-pitch strike rate should help on both fronts, and he's proven durable so far in his young professional career. With a rotation spot secured on what looks like a contending club, Flaherty should be viewed as a solid SP2 in mixed leagues.
Once seen as a likely No. 4 or No. 5 starter, the projectable 6-foot-4 righty finally delivered on the promise evaluators had long envisioned, with his fastball velocity jumping from the low-90s to the mid-90s in 2017. Exceptional command allowed him to profile as a back-end starter when he had middling stuff, and now that command allows him to project as a No. 3 starter. In addition to an improved fastball, Flaherty's slider also took a step forward, now profiling as his second-best offering. His curveball is more of a show-me pitch and his changeup is still developing, but has a chance to be a quality third pitch. Flaherty will not strike out a batter per inning, but should eventually be an asset in ERA and WHIP, and is ready to approach 200 innings. He got a brief taste of the majors last season, and will compete for a rotation spot this spring. One way or another, he figures to spend the bulk of 2018 in the big-league rotation, and makes for a decent flier at the end of deep-league drafts.
The 21-year-old Flaherty may not have the upside of some of the other pitchers in the St. Louis organization, but he achieved a good deal of success at High-A in 2016. The former first-round pick posted a 126:45 K:BB in 134 innings at that level. His fastball sits in the low-90s and is certainly not overpowering, but it does have a lot of movement. His changeup is above average, and Flaherty also features an emerging curveball and slider. In addition, Flaherty possesses an ideal frame at 6-foot-4, 205 pounds that should hold up to the rigors of being a rotation workhorse. Flaherty has the upside of a No. 2 starter and will begin the 2017 campaign at Double-A working to improve his secondary offerings.
Despite missing almost two months with a back injury at the start of the season, Flaherty managed to pass his first test pitching in a full-season league with flying colors. The 6-foot-4 righty posted a 2.84 ERA (2.83 FIP) with a 1.29 WHIP and 97 strikeouts in 95 innings with Low-A Peoria. He probably should have been challenged with a late-season promotion to the Florida State League, as his four-pitch mix was more than enough to dominate Low-A hitters. Flaherty will get his chance with High-A Palm Beach to start his age-20 season, but this may not be a one level per year arm, as the Cardinals might want to see how he fares in the upper levels at some point in 2016. A first-round pick in 2014, Flaherty has three pitches that could reach plus status, giving him a No. 2 ceiling, with the realistic floor of a No. 4 starter.
The Cardinals took Flaherty in the first round of the 2014 draft, inking the 6-foot-4 righty with a bonus well over the slot value for the No. 34 pick. He's several years away from contributing at the big league level but the Cardinals spent a lot to keep him from going to North Carolina for college. He was able to get in six starts in the Gulf Coast League for the Cardinals, posting an impressive 1.59 ERA and 28 strikeouts in just 22.2 innings as an 18-year-old. He could take some big steps forward in 2015, his first full year where his focus will be entirely on pitching, and if he can finish the season in High-A for the Cardinals it will be a great sign of things to come.

Latest Fantasy Rumors
Playoff run spelling LA reunion?
PLos Angeles Dodgers  
October 30, 2024
Derrick Goold of the St. Louis Post-Dispatch speculates that Flaherty's playoff performance could make it more likely he re-signs with the Dodgers during the offseason.
ANALYSIS
The right-hander has a 6.10 ERA through four playoff starts, though that figure is a bit inflated since he surrendered eight runs to the Mets in Game 5 of the NLCS. Flaherty is taking the mound Wednesday versus the Yankees in Game 5 of the World Series with a chance to close out the series, and a strong performance would make the ultimate case for Los Angeles to re-sign him as a free agent. The 29-year-old made 28 starts between the Tigers and Dodgers this season and has a 3.17 ERA 1.07 WHIP over 162 innings, which was his highest workload since 2019.
