The Cardinals announced they’ve selected the contract of top shortstop prospect Masyn Winn. Katie Woo of the Athletic reported Winn’s promotion just before the announcement. In a corresponding move, St. Louis is placing center fielder Lars Nootbaar on the 10-day injured list with a lower abdominal contusion, tweets John Denton of MLB.com. The Cardinals already had two vacancies on the 40-man roster.
Winn was St. Louis’ second-round pick out of a Texas high school three years ago. The canceled minor league season kept him from playing in a professional game until 2021. Winn has rapidly climbed the minor league ladder, spending most of last season in Double-A at age 20. He stole 28 bases while hitting .258/.349/.432 in 86 games there against generally older competition, cementing himself as one of the game’s top prospects heading into last winter.
The Cards assigned Winn to Triple-A Memphis this year. He has spent the entire season there, posting a .283/.356/.465 batting line in 494 plate appearances. The slash stats are aided by an offense-heavy Triple-A environment; of the 107 International League hitters with 300+ trips, Winn ranks 57th in on-base percentage and 43rd in slugging.
That production is partially weighed down by a very slow start to the year. Winn hit only .223/.287/.321 in April but has an OPS of .763 or better in every subsequent month. The right-handed hitter has feasted on southpaws, hitting .353/.425/.639 against them. His production against same-handed pitching is more modest — .258/.331/.401 — but that’s a small concern for a 21-year-old hitter at the top minor league level.
Winn has shown advanced contact skills, drawing walks at a decent 8.9% clip while striking out in only 16.8% of his plate appearances. He has connected on 17 home runs, 15 doubles and seven triples and gone 17-19 in stolen base attempts.
In addition to those promising offensive traits, Winn has a chance to be an impact middle infield defender. Prospect evaluators credit him with elite arm strength and the athleticism to stick at shortstop. While the Cards gave him 25 starts at the keystone in Memphis to broaden his flexibility, Winn has logged more than 2300 professional innings at shortstop.
Given the well-rounded profile and his upper minors success despite being so young, Winn is unanimously regarded as one of the top young talents in the sport. Baseball America ranked him the game’s #30 prospect on their recent update; Kiley McDaniel of ESPN slotted him 16th on his own refresh of the sport’s top prospects earlier in the week. Evaluators peg Winn’s power potential as solid-average while raving about the rest of his game.
The 5’11” infielder is generally viewed as the Cards’ potential long-term starting shortstop. St. Louis dealt Paul DeJong to the Blue Jays at the deadline. Tommy Edman has been the primary shortstop of late but is capable of moving around the diamond. Nootbaar will be out of action for at least the next week and a half after fouling a ball off his groin last night, while second baseman Nolan Gorman hit the 10-day IL this afternoon because of a lower back strain. Edman can cover the keystone or center field while the Cards give Winn regular run at shortstop over the season’s final six-plus weeks.
More to come.
