Orioles reliever Jim Johnson, who is nursing an elbow injury and not expected back anytime soon, was called up and placed on the 15-day disabled list.
It is pretty much a paper move, but it does carry ramifications for Johnson, who will accrue major league service time and big-league wages while he is on the DL. If he returns at some point in July, that's not that big of a deal. If he needs Tommy John surgery and is out all of next year, that will be a big deal because that's another year closer to free agency.
It sounds like the Orioles and Johnson's agent, Michael Moye, worked out a deal because Johnson had been on the minor league disabled list.
