Hafner in May, June and July is batting in the .170s. That's nearly three months of garbage. There's no a lefty bat anywhere to be found? They would rather have an automatic out at dh?
Hell matsui could hit that right now. I understand that this is a unusual year, but I can't see why you would stay with that production, The injuries to Musty in AAA has most likely kept Hafner on the payroll. Come Monday, I would designate him knowing Jeter and Arod would be sharing DH much of the way home.
