Janson Junk’s rehab start for Jacksonville ends early after line drive strikes his left wrist

Janson Junk took a step toward returning to the Miami Marlins rotation on Sunday with a rehab start for Triple-A Jacksonville, but the session ended earlier than planned after a line drive struck his left wrist. The team described the move as part of Junk’s recovery from right shin bone inflammation, a stint that had kept him from full-strength work.

In his first rehab outing, Junk faced Triple-A hitters in St. Louis and recorded 2 2/3 innings on the mound. The right-hander allowed three hits and a home run, while striking out three batters. Despite the early exit, the outing included command stretches, as he threw 42 pitches with 30 strikes.

The hit-by-contact was the decisive development. According to the MLB report, Junk was struck in the left wrist by a line drive, prompting the early departure from his start. For pitchers returning from lower-body or bone-related inflammation, a sudden impact to the pitching side adds an extra layer of uncertainty, even when the session has otherwise progressed.

The rehab start marked Junk’s first step back toward Miami’s big-league picture after the right shin issue. While a rehab appearance is designed to build arm strength and game rhythm, the outcome also affects how quickly a club can safely increase workload in subsequent sessions, especially when the session ends due to an injury event.

Jacksonville’s game served as the measuring stick for the next phase of Junk’s return process. The statistical line from the mound, including the home run and early innings total, offers only part of the picture. The immediate focus, as outlined in the report, is the condition of his left wrist and whether it allows further rehab progress after the incident.

What to watch next is the Marlins’ timeline for continuing or pausing Junk’s rehab after the wrist hit. In the meantime, the organization’s rotation planning will likely hinge on how quickly Junk can be evaluated and whether he can return for additional innings without aggravating the wrist. For now, Sunday’s rehab start is a reminder that even clean recoveries can be disrupted by a single moment of impact.

For Jacksonville, the rehab appearance also carried its own stakes, since Triple-A outing innings are often used to judge readiness against live, competitive lineups. Junk’s ability to miss bats at the Triple-A level, strikeouts aside, will be important if he resumes; the next report will likely focus on availability and how the wrist responds after this type of hit.
