Rest-of-Season Projections
2025 Fantasy Outlook
Coming back from a 2023 season shortened by arthroscopic left elbow surgery, Hjerpe was babied by the Cardinals for the first few months of the season at High-A Peoria, never exceeding four innings or 67 pitches in any of his 11 starts. They loosened the reins a bit upon a midseason promotion to Double-A Springfield, but unfortunately Hjerpe went down with more elbow trouble in early July which ended his campaign. When healthy, Hjerpe's performance was mostly encouraging, as he fanned 76 in 52.1 innings while collecting a 3.27 ERA. He also walked 28 batters, and avoiding free passes has been a consistent concern since he entered pro ball. Hjerpe, who works from a super low arm slot from the left side, needs to stay on the bump and find the strike zone in 2025. If he does that, he could be part of the Cardinals' rotation before the end of the season. Read Past Outlooks

Undergoes Tommy John surgery
Double-A Springfield transferred Hjerpe (elbow) from the 7-day injured list to the full-season injured list Tuesday.
ANALYSIS
Hjerpe recently underwent season-ending Tommy John surgery, which is notable after the 24-year-old dealt with elbow issues last season and didn't pitch after July 2. He was given a clean bill of health over the offseason, but he had yet to pitch in the minors early on this season. Hjerpe will miss another full season and has been limited to just 93.1 innings since being selected in the first round of the 2022 First-Year Player Draft.

Past Fantasy Outlooks
2024
2023
Hjerpe, a 6-foot-3 southpaw, put up very impressive numbers in college thanks to a unique arm angle that allows all his pitches to play up. He got off to a slow start in his pro debut, but he had a 1.54 ERA, 0.90 WHIP and 26 strikeouts in 23.1 innings over his final four starts before needing a cleanup procedure on his elbow. He made it back for the Arizona Fall League, and worked as a reliever there, striking out 15 while walking six in 8.1 innings over seven appearances. Including the AFL, Hjerpe was able to log just 49.1 innings after throwing 103.1 frames for Oregon State in 2022. Staying healthy and handling a starter's workload will be paramount this year, and if he does that, he could be an option in the big-league rotation in late 2024 or in 2025.
