Sosa (wrist) resumed his rehab assignment with Single-A Dunedin on Tuesday, going 1-for-2 with a double and a hit-by-pitch.
Sosa was pulled off his initial rehab assignment in late June following a setback. He should be ready to return later this month if he can avoid another snag in the recovery process, though it's unclear whether there will be room for him on the Blue Jays' active roster.
