Can you drop (or DL, for a temporary solution) someone to make a spot for Cabrera? If so, I'd do it, but still hang on to Greene on the bench until Cabrera sinks or swims.
Not sure about your pitching. Instinct would tell me to pick up Loaiza or Maroth, but I'd look into it more and get other opinions.
