Brett Graves (oblique) is set to be activated from the 60-day disabled list.
The transaction was not made before the start of Thursday afternoon’s game against the Giants, but it should happen Friday. Graves, a Rule 5 Draft pick from the A’s this past winter, registered a 5.59 ERA over 19 1/3 innings on a lengthy minor league rehab assignment between High-A Jupiter and Double-A Jacksonville. He will work in long relief for the Marlins.
