Mariners activated 1B/OF Corey Hart from the 15-day disabled list. Hart has been on the shelf since mid-May with a left hamstring strain, but he was cleared to return to action after batting .297/.366/.514 with one homer over 10 rehab games. He hit just .209/.295/.353 across 37 contests before going on the DL but did homer five times while driving in 17 runs.
