Graveman may have his turn in the rotation skipped, allowing Sean Manaea to start Friday against the Yankees, Joe Stiglich of NBC Sports California reports.
No official move as been made and it's unclear why the team would elect to replace the 26-year-old in the rotation. Stiglich reports that Jharel Cotton has emerged as a possibility take Manaea's place for Saturday, likely indicating a potential injury to Graveman. Further details should be coming closer to game time from the club.
