The St. Louis Cardinals have placed right-handed pitching prospect Max Rajcic on the 60-day injured list due to a significant right elbow injury. To bolster their pitching depth in response, the organization selected the contract of veteran left-hander Kyle Gibson’s teammate, veteran lefty John King, from Triple-A Memphis.
Max Rajcic Injury Timeline and Impact
Max Rajcic, a key figure in the Cardinals’ minor league system, faces an extended recovery period following the diagnosis of his elbow injury. By moving the 23-year-old to the 60-day injured list, the Cardinals have cleared a spot on their 40-man roster. According to MLB.com, this move effectively shelves Rajcic for at least two months, sidelining him during a critical development phase of his professional career.

Rajcic was selected by the Cardinals in the sixth round of the 2022 MLB Draft out of UCLA. He quickly climbed the organizational ladder, known for his command and ability to induce ground balls. The severity of the elbow issue remains the primary concern for the front office, as the team assesses the long-term prognosis for one of their higher-regarded pitching prospects.
John King Joins Major League Bullpen
The promotion of John King provides the Cardinals with an immediate, experienced option in the bullpen. King, 29, brings a track record of major league experience, having previously pitched for the Texas Rangers before joining the Cardinals organization.
The decision to add King to the active roster signals the team’s commitment to maintaining a veteran presence in the relief corps. According to Baseball-Reference, King has spent the early portion of the current season working in the Triple-A Memphis rotation and bullpen, refining his sinker-slider mix. His ability to work multiple innings or serve as a situational specialist provides manager Oliver Marmol with additional tactical flexibility during high-leverage situations.
Roster Management and Future Considerations
The Cardinals’ decision to swap a long-term prospect for an experienced arm highlights the current pressures of the 2024 season. With the 60-day injured list designation, the team gains temporary roster flexibility while Rajcic undergoes rehabilitation.
- Roster Status: Max Rajcic is ineligible to return to the active roster until his 60-day window expires.
- Bullpen Depth: John King’s arrival adds a left-handed option to a relief unit that has navigated various health challenges throughout the year.
- Prospect Development: The organization will monitor Rajcic’s recovery closely, with team medical staff overseeing his throwing program once he is cleared for baseball activities.
This roster adjustment reflects the Cardinals’ strategy of balancing the need for immediate production in the National League Central standings with the long-term health of their internal pitching pipeline. The team remains focused on stabilizing the pitching staff as they continue their mid-season campaign.
