Masyn Winn -- Prospect Evaluation

Masyn Winn is a 19-year-old two-way prospect for the St. Louis Cardinals selected in the 2nd round (54th overall) of the 2020 MLB Draft. Ranked #7 on the 2021 Cardinals Top 50 prospects, Winn began his professional career with the Palm Beach Cardinals in Low-A Southeast.

As a position player, Winn is a solid shortstop with excellent range and quickness. He possesses decent bat speed with projections for plus power as he matures, though he tends to be an aggressive hitter who swings at pitches outside the zone. He has plus speed and an above-average hit tool potential with refinement. Defensively capable of playing multiple infield positions, scouts project he will remain in the middle infield.

As a pitcher, Winn demonstrates significant arm talent with a fastball sitting in the mid-90s that tops out at 98 mph. His curve sits around 80 mph with sharp downward movement and projects as a plus pitch. His changeup, currently in the low 80s, is his weakest offering but could develop into an above-average pitch. Scouts view him as better suited for a bullpen role than starting. In his first professional game, he recorded an 88.5 mph throw to first on a double play, notably fast for a 19-year-old shortstop.

Overall, Winn projects as a viable two-way player at the MLB level, though the Cardinals' long-term development plan for him remains unclear. If focusing on either position exclusively, he should develop into an above-average player.

Masyn Winn joins the St. Louis Cardinals roster as one of baseball's elite defensive prospects, possessing one of only two 80-grade throwing arms among Top 30 prospects league-wide. The 21-year-old was originally drafted 54th overall in 2020 as a two-way player after throwing 98 mph fastballs as a high school pitcher, but his bat development has made him a viable position player. Winn demonstrated a significant offensive breakthrough at Triple-A Memphis this summer, posting a .359/.427/.750 slash line with 18 extra-base hits and 26 RBIs in 22 July games to earn International League Player of the Month honors. He led all Triple-A players with 97 runs scored and recorded 128 hits while facing primarily older hurlers across 445 at-bats before his callup. His breakthrough combined with the Cardinals' middle infield needs—Paul DeJong was traded to Toronto at the deadline and Brendan Donovan was sidelined with a right flexor strain—created the opportunity for Winn's promotion. Having played primarily shortstop but also significant time at second base, Winn is positioned to see immediate playing time. Notably, 11 of his 18 Triple-A home runs came off pitchers with major league experience, and he recorded his first multi-homer game as a professional in May.

The St. Louis Cardinals announced Thursday night the promotion of top shortstop prospect Masyn Winn to the major leagues, with his debut scheduled for Friday. The 21-year-old's arrival comes after the Cardinals traded Paul DeJong to the Toronto Blue Jays at the deadline and placed outfielder Lars Nootbaar on the injured list. Winn is widely regarded as one of the top shortstops in the minor leagues and should provide St. Louis with both immediate defensive upgrades and long-term potential.

Winn's most notable skill is his elite arm strength, with throws reaching triple digits and earning comparison as the strongest-armed shortstop in the NL Central division, surpassing recent promotions Oneil Cruz and Elly De La Cruz. Beyond his cannon arm, Winn combines slick fielding with above-average speed, giving him Gold Glove upside at the position. Paired with third baseman Nolan Arenado, Winn could provide the Cardinals with one of baseball's best defensive left sides of the infield.

The timing of Winn's promotion carries strategic significance regarding his rookie eligibility status. With 45 days remaining in the 2023 season, the Cardinals can carefully manage his playing time and at-bats to keep him under 130 plate appearances, preserving his rookie status for 2024. Should Winn win NL Rookie of the Year while retaining rookie eligibility, the Cardinals receive an early draft pick as compensation—similar to the Seattle Mariners receiving a pick for Julio Rodriguez—and Winn accelerates his path toward arbitration eligibility.

Masyn Blaze Winn (born 03/21/2002 in Katy, TX) was drafted 54th overall in 2020 by the St. Louis Cardinals for $2.1 million out of Kingwood High School. Standing 5'11" and weighing 180 pounds, Winn is evaluated as a legitimate two-way player with plus tools on both offense and defense. As a hitter, he demonstrates above-average bat speed, surprising raw power for his frame, and plus speed both in the box and on the basepaths. At shortstop, he exhibits exceptional athleticism, massive arm strength, solid hands, and strong instincts. On the mound, Winn reaches 98 mph with his fastball (typically 92-96 range) and pairs it with a hard slider showing slurvy characteristics and a plus changeup. His deceptive arm stroke enhances pitch effectiveness.

Scouts and teams remain divided on whether Winn's upside is better as a pitcher or hitter. At a Jupiter showcase, he produced one of the best two-way performances on record—flashing three plus pitches and generating exit velocities exceeding 100 mph three times. However, questions persist regarding his smaller frame, consistency on routine plays at shortstop, and plate discipline issues. Scouts suggest Winn needs to slow the game down, be more consistent defensively, and chase fewer pitches out of the zone. Some consider a reliever-only path due to size concerns, while others question whether he should follow the Brendan McKay model of continued two-way play. Despite obvious upside and talent, the prospect requires additional refinement and maturity. Winn has climbed from #11 (2021) to #1 (2024) in St. Louis Cardinals prospect rankings and was ranked #27 by Baseball America in 2023.

Masyn Winn, part of the Cardinals' 2020 draft class, has emerged as a top prospect and potential long-term shortstop solution for St. Louis. Originally considered as a potential two-way player, he settled into shortstop professionally and has attracted national attention, including a memorable 100.5 MPH throw at the 2022 MILB Futures Game that ranks among the strongest throws in StatCast history.

Winn was assigned to Triple-A Memphis in 2023 to advance his offensive production while leveraging his already elite defense. His offensive profile centers on contact skills, with a bat-to-ball approach that has generated above-average soft contact. Over 740 plate appearances in the high minors, he has maintained a .258 batting average but generated consistent on-base percentages, hovering around .340. Advanced metrics suggest his contact rate of 80.6% and zone contact rate of 86.8% significantly exceed league averages.

Despite modest raw power production (11 HR in 2022, 8 HR in 2023), scouts view Winn's toolset as the foundation for future development. His projection suggests potential to reach a .275+ batting average at full maturity, with the expectation that improved power output will follow as he continues to develop at higher minor league levels.
