2026 Fantasy Outlook
Winn did not take the step forward offensively in 2025 that many were hoping to see, instead watching his production tick down across the board. The question is how much of a role a right knee injury played in his offensive struggles. Winn reportedly began feeling soreness in the knee in late May/early June, and he finished the first two months of the season with a healthy .276/.352/.435 batting line and six home runs. The 24-year-old then slashed just .240/.287/.324 with three long balls the rest of the way before eventually succumbing to meniscus surgery in late September. Winn is expected to be ready to roll for the 2026 campaign, and with health he should bounce back to some degree. He could be more accumulator than upside play, however, as Winn's power has always been middling, and he hasn't been much of a stolen-base threat since Double-A in 2022. Read Past Outlooks

Winn (knee) will start at shortstop and bat sixth in Wednesday's contest against the Pirates.
Analysis
Winn had to sit out Tuesday's contest with a left knee injury, but he's feeling well enough to give it a go in the second game of the series after an MRI came back negative. The Gold Glove shortstop enters play Tuesday having slashed just .230/.298/.297 across his last 20 tilts.

Past Fantasy Outlooks
2025
2024
2023
2021
Winn was dreadful during a cup of coffee with the big club down the stretch of the 2023 season, but that didn't stop the Cardinals from handing him their starting shortstop gig heading into 2024. The youngster rewarded the club's faith with a quality rookie season, as Winn collected a .730 OPS with 15 home runs and 11 stolen bases while playing 150 games. Ten of Winn's 15 long balls came after the All-Star break after the infielder tweaked his approach to eke out more power, but it came at the expense of 37 points of batting average. Winn was the Cardinals' leadoff hitter from June on, which helped boost his counting stats, but with just a .290 OBP from the leadoff spot, he's no guarantee to stay there, especially not versus righties. The shortstop had an .818 OPS against left-handers in 2024 but just a .691 OPS versus right-handed pitching.
The youngest qualified hitter at Triple-A last season, Winn went on a summer-long heater that earned him a call to the majors late enough in the calendar to preserve his rookie status. He had a .553 OPS in his first 21 games at Triple-A and slashed .309/.383/.520 with 17 home runs and nine steals on 11 attempts over his final 83 games before getting the call. Over that stretch, his 14.7 percent strikeout rate and 9.5 percent walk rate were particularly impressive, even considering the automated balls and strikes system at Triple-A. Winn, a former two-way prospect, is probably known best known for his 80-grade arm at shortstop, however he's a great all-around athlete with plus speed and plus bat speed. He will turn 22 during spring training and is a shoo-in to enter the year as the everyday shortstop. Winn won't wow anyone with his exit velocities at this stage of his development, but his 81.7 percent contact rate, steady playing time and speed on the bases portends a fairly high floor. It should have surprised no one that he struggled initially in the majors, given his age, and a .196 BABIP played a role in that as well.
Winn has a couple really loud tools in his plus speed and 80-grade arm, and he comfortably projects as the Cardinals' shortstop of the future, assuming they don't sign one of the big free agents at the position this offseason. He played at multiple levels as a 20-year-old, riding a .431 BABIP to dominance in 33 games at High-A before putting up middling numbers at Double-A (.258/.349/.432) and the Arizona Fall League (.294/.407/.353). He was very young for Double-A and the AFL, but it's pretty clear his BABIP-fueled run at High-A is the outlier. He just needs to hit for double-digit homer power with an OBP in the .330-.350 range to be a roto monster who hits high in the lineup and helps across the board while threatening for 30-steal seasons. However, his 19.8 Hard% suggests there's still some work to do to be that impactful against upper-level pitching. His median outcome might be closer to a bottom-third of the order hitter who is targeted for his stolen-base contributions.
For fantasy, we want Winn, the No. 54 overall pick in last year's draft, to eventually focus full time on being a shortstop. Despite standing just 5-foot-11, 180 pounds, Winn's upper-90s fastball and breaking ball are each plus pitches, and his changeup has a chance to be a 60-grade pitch as well. He is also an elite athlete, which should help him harness his electric arsenal. For these reasons, St. Louis is developing him as a two-way player for now. However, if he were to be developed as a shortstop, his fantasy ceiling would rival that of any high school hitter in his draft class. He has plus raw power and is at least a plus runner, and while he currently chases too many pitches out of the zone, the expectation is that his hit tool would improve if he were focused solely on hitting. Winn continued to develop as a hitter and a pitcher at the alternate site after getting drafted.
