Logan Morrison (knee) will shift his rehab assignment to Double-A Jacksonville on Monday. Morrison has spent the past week with the High-A Jupiter Hammerheads, collecting three hits and one RBI in 13 at-bats. He's working his way back from September surgery to repair a torn patella tendon in his right knee and is currently aiming to join the Marlins in early June. NL-only leaguers might want to stash him now.
