As the regular season draws near, the St. Louis Cardinals are finalizing both their major league and minor league rosters, using the long-term injured list as part of their final adjustments. With Opening Day less than a week away, several roster decisions have been influenced by injuries, particularly among the organization’s developing pitchers.

A number of prospects have now been placed on the minor league 60-day injured list, signaling that they are likely to miss an extended period during the 2026 campaign. Among the most notable names are Sem Robberse and Zack Thompson, two pitchers who had already been reassigned from major league camp earlier in spring. Both players have dealt with injuries in the past, and their latest setbacks suggest those issues will continue to impact their progress this season.
Although these moves do not create immediate opportunities for players like JJ Wetherholt or Nelson Velázquez to secure roster spots, they still provide some insight into the current state of the Cardinals’ pitching depth. The use of the 60-day injured list typically indicates an absence of at least a couple of months, but in the minors, the criteria for placement are less strict. As a result, the exact nature and severity of some of these injuries remain unclear, leaving fans and analysts to make educated guesses about recovery timelines.
Robberse’s situation is more straightforward, as he is still recovering from Tommy John surgery performed last year. Given the typical recovery period for that procedure, his placement on the injured list was widely expected. Thompson’s case is less defined. After returning to the organization as a non-roster invitee, he appears to be dealing with additional physical setbacks, though specifics have not been disclosed.
Three other pitchers were also added to the injured list, further thinning the Cardinals’ minor league pitching depth. Brandon Clarke is recovering from surgery to address a shoulder aneurysm, a serious condition that required medical intervention. Additionally, recent draft pick Frank Elissalt and A-ball pitcher Andrew Dutkanych IV have both been sidelined, though details regarding their injuries have not been made public. In many cases, updates on lower-level prospects are limited unless team officials or front office members choose to share more information.
Another name included in the announcement is Reiner Lopez, a right-handed pitcher approaching his 20th birthday. Lopez has spent the past two seasons developing in the Dominican Summer League, gradually building experience and innings. His addition to the injured list represents another developmental setback for a young arm still in the early stages of his professional career.
While injuries are an unavoidable part of baseball, they can be especially damaging for prospects, as missed time can slow growth and delay advancement through the system. For the Cardinals, these early-season setbacks highlight the challenges of maintaining pitching depth while continuing to develop young talent.
