Ginn (undisclosed) has made minimal progress and may not pitch again this season, Martin Gallegos of MLB.com reports.
The A's pushed Ginn back from his most recent start and will send him to see an orthopedist Saturday to get a better read on the right-hander's condition. So far, the team has not provided specifics beyond fatigue and soreness. Ginn has not yet been placed on the injured list, but it sounds like that could happen in the coming days.
