So far this off-season, the Sox have all but completely ignored the bullpen, with the biggest additions being Ryan Watson and Tyler Samaniego. I could see adding maybe a Danny Coulombe into the mix., if you consider that spending.
One reason for the slow activity could be that the Sox are not close to adding anyone that they feel is a significant upgrade over the current 40 man roster, so there’s no one they want to DFA. If so, maybe they are on hold until such a time as Houck can be placed on the 60 day IL..
