Seattle Mariners Roster Update: Injuries Impact Key Players
The Seattle Mariners are managing a wave of injury-related roster adjustments as of June 9, 2026. Shortstop J.P. Crawford is the latest addition to the injured list, sidelined with a right hand contusion retroactive to June 6, while several other core players continue their recovery processes. These moves arrive as the club attempts to maintain its competitive standing during a demanding stretch of the season.
Status of J.P. Crawford and Recent Infield Injuries
J.P. Crawford was officially placed on the 10-day injured list on June 8, according to MLB.com. The move followed a 95.6 mph fastball that struck his hand, causing persistent pain that necessitated the roster change. Crawford is expected to be out until at least June 16 and will accompany the team through the conclusion of its current road trip on June 14.
The infield depth is further tested by the status of other key contributors:
- Colt Emerson: The shortstop/third baseman was scratched before the June 8 game against Baltimore due to back tightness, with his return timeline currently listed as TBD.
- Brendan Donovan: Currently on the 10-day injured list with a left groin strain, Donovan is working through a recovery program on a weightless treadmill.
- Will Wilson: Recovering from a fractured left thumb, Wilson began a rehab assignment with High-A Everett on June 5.
- Miles Mastrobuoni: Working back from a right calf strain, Mastrobuoni has been on the 60-day injured list since March 25 and is targeting a mid-June return.
Cal Raleigh’s Rehab Progress
Catcher Cal Raleigh, who has been on the 10-day injured list since May 14 due to a right oblique strain, is making measurable progress toward a return. According to MLB.com, Raleigh began a rehab assignment on June 7 with High-A Everett, recording a 1-for-3 performance. The club plans to transition him to Triple-A Tacoma on June 9, with a potential return to the major league roster during the homestand that begins June 16.

Comparison of Current Injury Timelines
The Mariners are navigating a range of recovery stages, as shown in the following summary of anticipated return windows:
| Player | Injury | Estimated Return |
|---|---|---|
| J.P. Crawford | Right hand contusion | June 16 (earliest) |
| Cal Raleigh | Right oblique strain | June 16 (potential) |

Looking Ahead
The Mariners’ ability to navigate this period of roster instability remains a focal point for the organization. With multiple infielders and a primary catcher working through rehab assignments or recovery programs, the team’s depth will be tested throughout the remainder of June. The medical staff continues to monitor the progress of players like Raleigh and Mastrobuoni, whose returns are critical for stabilizing the lineup as the team moves past its current road trip.
