2026 Fantasy Outlook
Fitts prepared to compete for a spot on the back end of Boston's rotation or its bullpen, but the Red Sox traded him to St. Louis to land Sonny Gray. That deal likely means Fitts will be part of the Cardinals rotation. The right-hander fought through a couple of injuries and made 11 appearances (10 starts) 2025, posting a 5.00 ERA with estimators suggesting luck was on his side (5.80 FIP, 5.55 xERA). Any encouraging contact rates from his four starts in 2024 went the other way in 2025, when he was hammered for 11 home runs in 45 innings. An arm injury eventually cut short his season in August, but Fitts was throwing in November and is expected to have a normal offseason. He's a fastball/slider starter and may need to develop another pitch or locate better. In St. Louis, beyond Matthew Liberatore and Michael McGreevy, the Cardinals are looking to fill out the starting staff. Fitts, even with his fringy stuff, could easily grab one of those spots, possibly as the third in the rotation ahead of Andre Pallante, who disappointed in 2025. Read Past Outlooks
Signed a one-year contract with the Cardinals in March of 2026.
Undergoes season-ending lat surgery
Fitts has undergone season-ending surgery on his right lat, Daniel Guerrero of the St. Louis Post-Dispatch reports.
Analysis
Fitts was placed on the 7-day injured list at Triple-A Memphis earlier this week with a lat strain, and testing revealed the need for surgery. Cardinals president of baseball operations Chaim Bloom said Friday that the long-term prognosis for Fitts is good, but the operation will cost him the rest of 2026 and it's possible he also gets a late start to the 2027 campaign. Fitts was acquired from the Red Sox over the offseason in the Sonny Gray trade and had posted a 1.76 ERA and 11:6 K:BB over 15.1 innings at Memphis.

2025 Fantasy Outlook
Once the dust settles this offseason, Fitts may not project to crack Boston's Opening Day rotation, but he appears ready to step up when a need arises. The 24-year-old righty struggled to miss bats in his four-start run in the majors (6.4 SwStr%, nine Ks in 20.2 IP), but he also limited hard contact (1.4 Barrel%) en route to a 1.74 ERA and 1.26 WHIP. The ERA estimators were split on his work (xERA, FIP in favor, xFIP, SIERRA against), but his pitches popped on the Stuff+ model, particularly his mid-80s slider (121 Stuff+), while Location+ (104) and Pitching+ (106) were also bullish on Fitts. He logged a 4.17 ERA, 1.28 WHIP and a 15.0 K-BB% in 116.2 innings over 24 appearances at Triple-A. Fitts has logged over 135 innings in back-to-back seasons and could make double-digit starts in the majors this year with a slight chance at a breakout.

Latest Fantasy Rumors
MLB debut incoming?
Red Sox GM indicated Sunday that Fitts will be considered for major-league starts during the final six weeks of the season, reports Chris Cotillo of MassLive.com.
Analysis
Breslow cited the right-hander's strong performance in August, as he has a 2.12 ERA, 1.00 WHIP and 19:2 K:BB across 17 innings through three starts. Fitts' 4.42 ERA and 3.2 BB/9 for the season are a bit less encouraging, but the improved results this month have put his big-league debut within reach.
