With the Red Sox having just brought Nathan Eovaldi back on a four-year deal and signing Steve Pearce to a one-year deal earlier in the winter, they have just one more mission left for the offseason. Well, at least in terms of positions to fill on the roster. There are still moves that can and will be made — most notably in likely dealing one of their three catchers — but the one big task that remains is beefing up the bullpen. The preference here is that they bring aboard two new relievers, but grabbing at least one is certainly necessary.
