East losing its grip
It's still early.
I wrote that twice because I enjoy writing things twice, and also because it's still early. Or at least it's still early enough that we can't draw any grand conclusions about qualitative differences between particular divisions. Still, if one is looking for symbols, Travis Hafner's game-winning grand slam at Fenway Park last night is a pretty good symbol for the American League Central's success this season against the AL East.
