While not exactly a modern metric, Aaron Boone is convinced the New York Yankees have their highest kumbaya in years. "The closeness that these guys have with one another and that trite 'playing for one another' is palpable with this group, has been all year, has been since day one," the manager said Monday, four days ahead of the World Series opener against the Los Angeles Dodgers. Seeking their 28th title, the Yankees are in the World Series for the first time since winning the 2009 championship.
