Also, there are some disturbing rumors that Manny purposely left his bat on his shoulder & struck out in a critical situation vs. Mariano Rivera earlier this month. I remember watching that at bat & being totally amazed that Manny didn't swing. And now it makes total sense.
The Red Sox can tolerate Manny being clownish & incompetent in left field -- clearly we have already stomached it for this long. But if he goes into pouty & surly Manny mode, it won't be much longer for him in Boston. He will go the way of Nomar.
