Konnor Griffin (left ring finger) to begin Double-A rehab assignment Sunday

Konnor Griffin is scheduled to begin a rehab assignment at the Double-A level on Sunday, per Aiden Stepansky of MLB.com, as the Pittsburgh Pirates prospect continues his recovery from a left ring finger injury.

The assignment puts Griffin back on a competitive field, though what remains unconfirmed is any timetable for a return to the active roster or how the rehab stint is expected to progress. A Double-A assignment is a standard step in the process — enough live action to test the finger without the full weight of a major-league environment.

What to watch

How Griffin performs and how the finger responds to game action will shape whatever comes next. No further details about duration or next steps have been reported.
