2025 Fantasy Outlook
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. Read Past Outlooks
Signed a one-year contract with the Cardinals in March of 2025.
Set for knee procedure
Winn is expected to undergo arthroscopic surgery within the next two weeks to address a torn meniscus in his right knee, Katie Woo of The Athletic reports.
Analysis
Before Winn was placed on the injured list Saturday, manager Oliver Marmol confirmed that the slick-fielding shortstop won't take the field again in 2025 since he hadn't bounced back as well as the Cardinals had hoped while playing through the knee injury over the last several weeks. The surgery should help provide more permanent relief for the 23-year-old, who previously had a similar procedure on the same knee in high school, according to Derrick Goold of the St. Louis Post-Dispatch. Winn noted that after the previous surgery, he had resumed playing within three months, and the expectation is that he'll be available as a full participant for the start of spring training in February. Thomas Saggese has started each of the Cardinals' last five games at shortstop and is likely to serve as the primary option at the position for the remainder of the season.

How does Masyn Winn compare to other hitters?
This section compares his stats with all batting seasons from the previous three seasons (minimum 400 plate appearances)*. The bar represents the player's percentile rank.

Past Fantasy Outlooks
2024
2023
2021
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.

Latest Fantasy Rumors
Extension not close
According to Katie Woo of The Athletic, Winn and the Cardinals have not had "concrete conversations" regarding a contract extension.
Analysis
The 22-year-old delivered an impressive rookie campaign in 2024 with 15 homers, 11 steals and a .730 OPS in 150 games, but there's no rush on extension talks since he won't have his first year of arbitration eligibility until 2027. Winn also flashed his defensive skills and totaled plus-14 Defensive Runs Saved and plus-three Outs Above Average, so he should be a lineup staple for St. Louis for the foreseeable future.
