The Marlins placed rookie closer Henry Owens back on the disabled list with right shoulder inflammation. From the mlb.com story, he says "the two injuries are unrelated. The rotator cuff problem was in the front of his shoulder, while the current ailment is in the back."
To me it sounds bad, but that isn't the point. What interests me is the acquistion of Armando Benitez makes more sense now. Assuming the Marlins withheld some information about the previous injury - information that would make them wary of Owens' season-long health, then getting Benitez to pitch late in the game was a shrewder move than previously thought.
I am almost ready to connect a returning disabled player and the transaction to add a player who plays the same position as a signal the returning disabled player is not considered likely to remain healthy.
