Garcia (elbow) will throw a bullpen session Saturday, Brian McTaggart of MLB.com reports.
Saturday will mark Garcia's first time throwing off a mound since July 4, as the Astros opted to pull him off his rehab assignment following a rough outing in Double-A. He will likely need to throw a few additional mound sessions before resuming his rehab stint, at which point he'll require multiple starts as he works his way back from Tommy John surgery.
