Sanchez (chest) is slated to throw a simulated game Sunday, Jason Beck of MLB.com reports. The right-hander threw 40 pitches off a mound Thursday, his third mound session of the week, and will now look ahead to facing live hitters Sunday morning. According to the report, Sanchez is upbeat about a possible return next week, though the team has yet to clarify whether he'll work as a starter or as a reliever immediately upon his reinstatement from the DL.
