This weekend’s series against the Yankees at Fenway isn’t quite over yet, but it’s already been everything we could have asked for and more. The Red Sox have taken care of business in the biggest series of the year, and that’s putting it mildly. They’ve already clinched the upper hand in the four-game set by taking the first three games, and at worst they’ll leave Boston and head to Toronto with a 7.5-game edge in the American League East. Even the most optimistic of us probably didn’t see that happening at any point this year.
