I still think that by the AS break, Craig Hansen could be the closer. Since he's been in Boston, he's pitched opposite of strength, which is dominating sinker, both sides of plate, and his slider. He got wrapped up in radar gun readings of high fastballs and pitched opposite of what made him such a great prospect. And I think John Farrell will have a very strong influence on him.
From your mouth to Theo's ears, Peter... though I suspect it's actually the other way 'round! ^_^
