Yesterday, I gave a run down of the 2007 National League closers with the main dispute being the one in Cincinnatti. Today, I run the AL closers and their main back-up as I see things right now. There are some back-ups that will change or will be much discussed to change i.e. Akinori Otsuka, but I won't jump the gun (this time) and list another member of those 'pens until something is actually done.
