It seems like we're looking at another "team of destiny". Think Cardinals last year, or the 2007 Rockies (even though they lost). I'm locking in this play right now.
I already have Yankees +600 to win the WS before the season began. If things hold up as they are now and the Yankees win tonight, it is possible the Yanks/A's meet in the ALCS, and I'll have a sweet hedge opportunity in the WS.
