Sox are going to roll with the current group until Memorial Day. I wouldn't expect substantial changes until then. I don't know why Breslow should start sitting guys and sending others to AAA because of a two week sample. Would we do the same after a two week sample in July? Probably not.
Only 3 fulltime players have an OPS above 700: Abreu, Contreras and Rafaela. Wong and Masa are over 700, but neither have seen increased playing time. Calling up Cheng isn't going to make up for 6 underperforming starters.
