Cardinals Face A Real Decision On Jurrangelo Cijntjes MLB Debut

As the Memphis Redbirds gear up for the postseason, the St. Louis Cardinals weigh the potential impact of giving standout prospect Jurrangelo Cijntje his Major League debut.

The Cardinals have a chance to give Jurrangelo Cijntje a real big-league test before this season runs out, and there’s a pretty clean case for doing it.

Cijntje, the top prize from the Brendan Donovan trade this offseason, has taken his lumps along the way this year. He wasn’t sharp for long stretches, but he found his footing at Double-A, then moved up to Triple-A in July. After needing a little time to get used to throwing the Major League ball, he’s been rolling on the mound.

Over his last seven starts, Cijntje has posted a 2.86 ERA with 41 strikeouts in 34.2 innings. His 28.9 K% and 7.7 BB% in that span stand out, and he’s also carrying a 2.44 FIP. In his final regular-season start of the year for Memphis, he threw 5 1/3 scoreless innings.

The numbers back up the bigger point: this is a Cardinals team still trying to sort out who belongs in the 2027 rotation, and Cijntje deserves a look. He already ranks second in all of minor league baseball in strikeouts this season, sitting just ahead of another Cardinals prospect, Daniel Eagen, who came over in the Lars Nootbaar trade at the deadline. For an organization trying to stockpile more swing-and-miss arms, getting Cijntje in front of Major League hitters now could be part of the development process.

That matters because he’s shown a pattern of starting slowly whenever he’s bumped to a new level before settling in and dealing. A September call-up would let him feel what it’s like to pitch on that stage, see how his stuff plays, and head into spring training with a better sense of either what he can already do or what still needs work.

There are also two roster complications to weigh. The Cardinals have two open spots on the 40-man roster, but Cijntje is not Rule 5 eligible until next December, which means they could leave him off the roster all offseason and still bring him to camp as a non-roster invitee. If he pitches well there, he can still earn a job.

The other issue is what happens if Major League Baseball misses games next year. If Cijntje is on the 40-man roster, he would not be able to pitch in minor league games during a lockout. If he stays off it, he would still be able to play because he’d be covered by a different collective bargaining agreement.

Even with those considerations, this feels like the kind of move that could help both now and later. And yes, it would be fun to see him soon.

Cardinals May Be Headed For The Big Spending Move Fans Want

The Cardinals have spent much of the season outpacing the modest expectations that followed them into April, and that has opened the door to a different kind of conversation around the roster. If the front office decides the club is ready to make a real push, third base looks like one of the spots that could justify a bigger swing, especially with the current production at the position lagging behind the rest of the lineup.

Bo Bichette has emerged as a name that fits both the need and the moment. He has been working mostly at third base this season while still providing the kind of offense and leadership that tend to travel well in free agency, and he is attached to a deal with two years and $84 million left, plus a player option for 2027. For a Cardinals team trying to balance caution with ambition, the question is whether this is the kind of spending move that signals they are ready to act like contenders. [Read more 🡒]

Cardinals Suddenly Have A Worry With One Breakout Young Bat

Joshua Bez has given the Cardinals one of the more encouraging young-bat stories of the season, flashing real pop since his MLB debut and quickly making himself part of the conversation in St. Louis. Through 29 games, he has already shown the kind of offensive punch that can change how a lineup looks, which is why his early exit against the Giants drew immediate attention.

Bez left that game because of tightness on his left side and is now being treated as day-to-day, a reminder of how quickly a breakout can be tested. The timing is at least a little favorable for the Cardinals, who have a day off before their next game, giving him a little extra recovery time while the team waits to see whether this is a short scare or something more significant.

JJ Wetherholts Return Just Changed A Cardinals Roster Battle

JJ Wetherholt is back on the Cardinals' active roster after the club activated the rookie infielder from the 10-day injured list, a move that immediately reshaped the infield picture in St. Louis. To clear space, the Cardinals designated infielder Ramn Uras and right-handed pitcher Peter Strzelecki for assignment, a reminder that roster churn can turn quickly this time of year.

Wetherholts return comes after a season in which he has already logged 130 games, giving St. Louis a young option back in the mix as the team sorts out its finish. Uras had appeared in 43 games for the Cardinals, while Strzelecki made eight appearances, and their exits leave the organization with another decision to navigate as Wetherholt reenters the fold.
