The only silver lining about Romano is its a back thing and not an arm thing. But he might have to take some time to rest it. If that means a DL stint you do it. Can't afford to go 2 relievers short when you factor in Mitch White occupying and stealing a spot of an actual Major League picture currently.
There's a dominant late inning reliever on the market. He's a rental but he would be a hell of a rental. And ultimate insurance for Romano. Chad Green is a nice. But he's no Josh Hader.
