2023 Fantasy Outlook
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.

Tosses quality start Saturday
Flaherty allowed one run on seven hits and one walk while striking out four batters over seven innings in a no-decision against Cleveland on Saturday.
ANALYSIS
Flaherty has struggled mightily with free passes this season -- he entered Saturday with 33 walks over 51 innings -- so it was a a big step in the right direction for him to walk just one batter in the outing. The improved control helped the right-hander tie his season high with seven innings, and he picked up just his third quality start over 11 appearances. Flaherty induced only six swinging strikes and posted a modest four punchouts, but this was nonetheless one of his best starts of the campaign. Though his 4.81 season ERA is nothing to celebrate, it's trending in the right direction again after ballooning to 6.29 following a 2.1 inning, 10-run blowup against the Angels on May 4.

2015
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.
