Because they were close with the Cardinals for the division, used up their top starters. The Cards were ready to use Wainwright on the final game of the season, but they luck out.
O's definitely looks the strongest. Good lineup, strong rotation, excellent bullpen. As long as Jones or Cruz don't pull s*** in the OF, they have to be favorite to go deep.
