2019 Fantasy Outlook
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. Read Past Outlooks

Sustains first loss
PSt. Louis Cardinals
April 16, 2019
Flaherty (1-1) took the loss Tuesday, allowing five runs on nine hits and one walk while striking out four over 2.2 innings against Milwaukee.
ANALYSIS
Flaherty wasn't fooling the Brewers, and permitted all five runs in the third inning highlighted by homers from Lorenzo Cain and Yasmani Grandal. The 23-year-old was removed with two outs in the third inning after 75 pitches. The poor outing inflates his ERA to 5.00 and his WHIP to 1.61 after four starts, and he'll look to rebound in a rematch with Milwaukee at home Monday.

Past Fantasy Outlooks

2016
2015
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.
