This piece at the Daily Dish says that the Red Sox are targeting pitchers, and further notes that the A's "are expected to be selling." On behalf of Billy Beane, I make the following over to Theo Epstein.

Red Sox acquire: Guillermo Moscoso, RHP, 2.16 ERA
Athletics acquire: Ryan Lavarnway, C, AAA, has never played in the majors

This strikes me as an entirely fair deal.
