2025 Fantasy Outlook
Falter got his most extended opportunity as a starter in 2024 by taking 28 turns through the rotation as a member of the Pirates. His 4.43 ERA and 1.29 WHIP were both unremarkable, and those results were backed by similarly uninspiring skills. His strikeout rate dipped to 16.5 percent, and his career 9.2 percent swinging strike rate doesn't suggest there's much additional upside. The positive from his profile was his ability to blend a relatively high 42.1 percent flyball rate with a more muted 1.1 HR/9. That could offer a streaming opportunity in favorable pitcher's parks or power-deficient lineups, so long as Falter can stick in the rotation. The latter point is hardly a given with Johan Oviedo (elbow) likely to be back in the mix, as well as promising prospects such as Thomas Harrington, Braxton Ashcraft (forearm) and Bubba Chandler all likely to reach the majors at some point in 2025. All told, Falter should be on the radar for NL-only leagues, but his appeal in mixed formats should be a streamer at most. Read Past Outlooks

Falter (7-6) took the loss against the Red Sox on Monday, allowing seven runs on eight hits and two walks with two strikeouts over four innings.
Analysis
Falter was mostly undone by a five-run first inning and managed just one scoreless frame in a lackluster debut with his new club. The southpaw generated only six whiffs on 88 pitches, though a Jarren Duran homer was the lone extra-base hit he allowed. He owns a 4.14 ERA, 1.23 WHIP and 72:41 K:BB across 117.1 innings and is tentatively slated for a home matchup with the Nationals early next week.

Past Fantasy Outlooks
2024
2023
Falter was flipped from Philadelphia at the trade deadline in 2023, though his role, workload and skill all remained nearly identical before and after the trade. He threw a total of 80.2 uninspiring innings in the majors, as he saw his velocity dip to the lowest mark of his career (90.9), with a corresponding dip in swinging strike rate (7.9 percent) and strikeout rate (17.3 percent). Even on a team with a relatively uninspiring group of starters, it's unlikely that Falter will be able to earn anything more than spot starts and a bullpen role. Though he's not a closer of the future, Falter has had more success in relief in his career, holding opponents to a .303 wOBA with 52 strikeouts across 56.2 innings. He could turn into a relatively successful multi-inning reliever, though the fantasy value of that in most league formats is minimal.
Falter spent last season as the Phillies' sixth starter and was needed in the rotation for roughly half the year, making 16 starts and four relief appearances. The results were perfectly respectable for the second-year lefty, as he finished the year with a 3.86 ERA and 1.21 WHIP in 84 innings of work. He didn't provide much in the strikeout category, but his 21.2 K% was close enough to league average and paired well with his 4.9 BB%. Throwing that many strikes is a good thing, but allowing plenty of contact can be an issue at cozy Citizens Bank Park. His 1.7 HR/9 overall was poor, and that number spiked to 2.1 at home, leading to a 5.49 ERA. Falter's 31.7% groundball rate was sixth-lowest among pitchers who threw at least 80 innings, so don't expect those homer problems to disappear any time soon. Still, if he's able to win a rotation spot, his control is good enough to make him usable in the right spots, especially on the road.

Latest Fantasy Rumors
Makes Pirates history
PPittsburgh Pirates
June 3, 2025
Falter's 0.76 ERA across six starts in June is the lowest mark by a Pirates pitcher that made at least six starts in a month since 1920.
Analysis
The left-hander's fantasy upside continues to be limited due to his low strikeout numbers, but he was dominant in May with just three earned runs allowed and a 19:13 K:BB across 35.2 innings. Falter was a decent rotation piece for Pittsburgh last year with a 4.43 ERA in 28 starts, but he's looking like a borderline All-Star early in 2025 with a 3.14 ERA and 1.08 WHIP across 66 innings.
