Garrett (forearm) is scheduled to make a rehab start with Single-A Jupiter on Thursday, Kevin Barral of FishonFirst.com reports.
The left-hander progressed to throwing live batting practice over the weekend and has been deemed ready for game action after a bullpen session Tuesday. Garrett is expected to throw about three innings and/or 50 pitches Thursday in the first of what's likely to be a couple rehab starts. He's been on the shelf since mid-June due to a forearm strain.
