Here are my guesses:
Sox acquire Brandon Nimmo from the Mets for Blake Rutherford, Seby Zavala and Codi Heuer
Sox trade Jose Abreu, Welington Castillo and cash considerations to the A's for Sheldon Nuese
Sox trade Alex Colome to the Dodgers for Josiah Gray and Kyle Garlick
Sox trade Jon Jay and Evan Marshall to the A's for Resley Linares
Yolmer traded to somebody for a warm body
