The "closer" is a ceremonial "position" at best. Our best reliever, Marmol, should be free from such distinctions in order to pitch out of tight spots, which is exactly what's going to happen (probably, I hope). Some of you are really overthinking this. "Well, Kerry Wood trims his fingernails super-short, and there's an old Confucian analect that says "man with short fingernail scratch balls long time," meaning, he'll somehow be worse in the 9th inning than he is in any other inning because of this."
