Jim Johnson's time as A's closer was remarkably short, and his tenure with the team now might be close to done.

Sources confirmed that the A's nearly traded Johnson to the Marlins for a competitive-balance draft pick and a player last week, a development first reported by Fox Sports' Ken Rosenthal.

Johnson is still available, in the right deal, and Oakland could be willing to pick up most or even all of the remainder of his $10 million deal depending on the return for him.

The A's are not looking to move Johnson for depth, or for immediate help; the primary benefit of a deal would be to free up a roster space, especially with Eric O'Flaherty (Tommy John surgery) coming off the disabled list before the end of the month. If the team trades him, "it will be addition by subtraction," one source said.
