Ginn (undisclosed) is dealing with some fatigue/soreness, Martin Gallegos of MLB.com reports.
Ginn had his latest turn in the rotation skipped Tuesday against Texas, and he's dealing with some unspecified fatigue/soreness prior to Thursday's series opener with the Mariners. The right-hander won't pitch at all during the team's four-game series in Seattle, and the A's haven't made a decision on a potential stint on the injured list for Ginn.
