The news that they're capable of actually making a mid-season trade is bigger news that the pieces involved in this instance, however, since the only player of note making a move is Boston Red Sox farmhand reliever Miguel Celestino, according to Mike Antonellis.

Antonellis, by the way, is the radio voice of Boston's AA affiliate, the Portland Sea Dogs, where Celestino spent much of the last three seasons. Mike later added that Celestino will be heading to Pensacola.
Celestino is a big righty, a 6'6" 205 lb 25 year old who was signed out of the Dominican Republic by the Seattle Mariners when he was just 17.
