3 Cardinals prospects who should not get a September call-up

As the season winds down for teams with no real chance of making the postseason, taking a look at players who could be part of their future success makes sense a lot of the time, but not all the time.

Is there a Triple-A player knocking down the door, all but demanding a big-league opportunity with his performance? Sure, bring him up. Did the team trade away a starter, and now they need someone to fill in, even if they're not quite ready? Hey, let's see what the kid can do. He can always go back to the minors next year to work on his development some more.

But is this always the right move? Not necessarily. Maybe a prospect really isn't ready to make the leap to the majors, and there is the risk of hurting his confidence by allowing him to fail on the game's biggest stage. Getting rushed and flopping can't feel good, and it's possible that performance has a lingering effect on his game.

Service time manipulation has been an issue for a long time, and while it's different under the new Collective Bargaining Agreement, it might be better and worse at the same time. Perhaps a minor league player is showing he's ready for a late-season call-up, but the team doesn't want him to get on a jump on his service clock, with the plan being to keep him in the minors until mid-April next year when they'll lock in a seventh year of control.

And then there are Rookie of the Year considerations. A player who spends more than 45 days on the active roster, exceeds 130 at-bats (not plate appearances), or tops more than 50 innings pitched loses rookie eligibility. Teams now are incentivized to start their best prospects on Opening Day, since a top-100 prospect who spends a full-service year (172 of 182 days) on the major league roster and finish in the top three in ROY voting earns his team an extra draft pick after the first round.

All of these factors have to be considered when deciding the proper time to call up players. And for St. Louis, things shake out such that a few players should not see Busch Stadium before 2024.

Here are three prospects that should not receive a September call-up from the Cardinals

Masyn Winn

The Cardinals thinned out their middle-infield logjam with the trade of Paul DeJong to the Blue Jays, one of three deals this season between St. Louis and Toronto. This move left Tommy Edman as the primary shortstop and cemented Nolan Gorman as the everyday second baseman. Of course, few players are truly "everyday" players, so Brendan Donovan (when healthy) and Taylor Motter are available to provide rest when Edman and Gorman need it.

Masyn Winn is tearing it up at Triple-A Memphis this year. Through August 11, he was hitting .286/.356/.467 with 17 home runs, an equal number of stolen bases, and 94 runs scored in 101 games. This 21-year-old prospect is ready to shed that label and replace it with "major leaguer."

But is bringing Winn to The Show the correct move for the Cardinals? The benefits are exposure to the highest level to get him ready for next season and some excitement for the fans in this down season.

The drawbacks are the risk of interrupting a strong season one rung below the majors, either by poor performance or by allowing Winn to sit on the bench too much, getting a taste of the big league environment but not enough on-field action. After all, Edman and Gorman do need to continue to play a lot.

The service time issues of 45 days or 130 ABs are easy enough for the Cardinals to control. The ROY potential for next season is more difficult to gauge. Is there any guarantee Winn will finish in the top three of ROY voting? Of course not. Sure, he looks great now, but lots of things can affect how a youngster plays when he first reaches the majors.

The most likely scenario for St. Louis is to keep Winn in Memphis all of 2023 and start him there to begin the 2024 campaign, with Winn likely to reach the majors around Tax Day of next season. It's probably not fair, and it might not even be prudent if he does earn a top-three ROY finish.

However, the benefit of a draft pick around No. 35 probably doesn't outweigh locking in the risk of losing Winn a year earlier than the CBA permits. I expect the typically conservative Cardinals to play it that way, all but ensuring control over Winn through the 2030 season.

(Almost) all of the newly acquired prospects

Okay, so this isn't going to be about the specific third prospect the Cardinals shouldn't call up. It's actually about the rather large number of new prospects St. Louis traded for leading up to the August 1 trade deadline. Given where the big league team is headed and the status of their new acquisitions. promoting just about any of them doesn't make much sense.

Among the current big leaguers, Dakota Hudson and Matthew Liberatore should be given opportunities to show what they can do in the rotation. The team also should give strong consideration to including Zack Thompson in the starting mix, even if that means going to a six-man rotation or bumping Cardinals legend Adam Wainwright to the bullpen amid his painful-to-watch final season.

There simply aren't rotation spots available this year for Drew Rom, and Sem Robberse, with the latter not yet on the 40-man roster. Meanwhile, Tekoah Roby is still recovering from a shoulder injury, so there's a very different focus for him than considering a big-league debut.

On the position player side, Cesar Prieto has played third base, second base, and a little shortstop in the minors, positions at which the Cardinals already have good depth. Thomas Saggese has a similar defensive profile to Prieto, and he's currently at Double-A Springfield, so the odds are even slimmer of him making an appearance at Busch Stadium this year. Given St. Louis' roster construction, it wouldn't be surprising to see either or both of these players dealt in an offseason move to acquire even more pitching.

About the only reasonable call-ups among the newly acquired talent would be relievers Adam Kloffenstien, currently pitching for Memphis, or - as a real stretch - Matt Svanson, who is toiling for Springfield. Relievers are fickle, so seeing what either of them could do against major league hitters this September might give the Cardinals a slightly better sense of their ability to contribute to the bullpen next season.

Sometimes teams will bring their new acquisitions to the majors to give fans a demonstration of what all the trade deadline deals were about, to let them see those transactions are paying dividends right away, even if immediate impact is not the real intention of those moves. For St. Louis, most of their fans know better, that what's most important is figuring out who on the current roster should stick around while using the minor leagues to continue refining the skills of their youngsters in full-time roles so they'll be ready to help the big league squad when their number is called.
