Yes the Yankees are in first place and have taken a sizable lead in the division but that does not equal a turning of the tide in the rivalry and does not equal a World Series championship as some would have you believe. Take this joke of an article from John Harper in the NY Daily News:
the Yankees on the verge of burying the Red Sox deep in the standings with a four-game sweep, the Rivalry has taken a rather stunning turn back to more familiar Yankee dominance.
And it's at least partly because the Yankees, for a change, are winning the battle of the front offices. Going back to the winter when he swooped in to steal Mark Teixeira from the Red Sox, Cashman this year is outmaneuvering Theo.
