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 had to be 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 setback, though it's unclear whether there will be room for him on the Blue Jays' active roster.
