My point about luck wasn't so much about the Yankees playing above their level (according to peripherals), but it was that the Yankees were lucky that players such as Overbay, Hafner, Wells (outcasts from other teams way past their primes) are hitting like they are in their primes again. Obviously the Yankees have been unlucky enough to have to rely on those players, but they are lucky they aren't buried in the division, let alone leading it.
