If it seems like forever since the Red Sox have played a team other than the Yankees or Rays, it’s because it has been. The long 14-game stretch against the two division rivals finally ended on Sunday and in the worst possible way.

If there is going to be a recovery, they have to take advantage of their schedule softening up in the near future, beginning with this series against the Royals.
