EDGE Analysis
Kloffenstein began the 2025 campaign on the injured list due to right shoulder fatigue. He'd looked sharp up until his last outing Saturday against Worcester, when he surrendered three runs on three hits and seven walks over 2.2 innings, his first earned runs allowed on the year.

Kloffenstein is dealing with right shoulder fatigue but recent underwent an MRI that came back negative, Keegan Matheson of MLB.com reports.
EDGE Analysis
Kloffenstein missed the final two months of the 2024 season with a right shoulder injury, so it's certainly not ideal that he's still battling shoulder issues. However, the expectation is that he'll be ready to resume throwing in a few days. If healthy, Kloffenstein projects to open the 2025 season in the rotation at Triple-A Buffalo.

The Blue Jays signed Kloffenstein (shoulder) to a minor-league contract that includes an invitation to spring training Tuesday, Ari Alexander of KPRC 2 Houston reports.
EDGE Analysis
Kloffenstein missed the final two months of the 2024 season with a right shoulder injury and was non-tendered by the Cardinals even though he was not yet eligible for arbitration. It's not clear what his health status is, but the Blue Jays felt good enough about the righty to invite him to camp. Kloffenstein was dealt from Toronto to St. Louis at the 2023 trade deadline as part of the return for Jordan Hicks.

The Cardinals non-tendered Kloffenstein (shoulder) on Friday.
EDGE Analysis
Kloffenstein was placed on Triple-A Memphis' 7-day injured list in late July due to right shoulder discomfort, and the injury was serious enough for him to be sidelined for the rest of the 2024 campaign. He went 4-5 across 17 starts in Triple-A and posted a 4.74 ERA, 1.34 WHIP and 73:41 K:BB across 89.1 innings.

Kloffenstein was placed on Triple-A Memphis' 7-day injured list Wednesday due to right shoulder discomfort, Jeff Jones of the Belleville News-Democrat reports.
EDGE Analysis
The right-hander made his major-league debut June 20 with a scoreless inning against San Francisco, but he's otherwise spent the campaign at Triple-A. Kloffenstein's shoulder is still being evaluated, so it's unclear how long he'll be sidelined.

EDGE Analysis
Kloffenstein turned in a 1-2-3 inning in his major-league debut Thursday versus the Giants to help out a depleted Cardinals bullpen but will quickly head back to Memphis. The big righty will re-enter Memphis' starting rotation, where he's collected a 3.97 ERA and 1.13 WHIP through 77 innings across 14 starts.

The Cardinals recalled Kloffenstein from Triple-A Memphis on Thursday.
EDGE Analysis
After putting up a 3.97 ERA and 1.13 WHP through 77 innings at Triple-A, Kloffenstein will now come up from the minors to give St. Louis another multi-inning relief option in its bullpen. He'll take the place of Chris Roycroft, who was optioned to Memphis in a corresponding move.

The Cardinals will recall Kloffenstein from Triple-A Memphis on Thursday, Katie Woo of The Athletic reports.
EDGE Analysis
Kloffenstein has spent all season with Memphis, posting a 3.97 ERA and 1.13 WHIP through 77 innings across 14 starts. Although he has been used almost exclusively as a starter throughout his minor-league career, he will likely be used as a multi-inning reliever while with St. Louis. The 23-year-old righty will be making his MLB debut whenever he gets into a game.
