Cardinals are always clutch in big games i'd probably go with them at 8-1 if i had to pick 1.
Maybe Tigers, Nationals, Dodgers or A's would be good ones since they are all pretty much locks to make the playoffs.
Braves always choke, Red Sox won't repeat, Rangers not enough pitching other than Darvish.
As long shots I like the Orioles, Jays to win the AL East.
Also Brewers, D-Backs, Phillies, Rockies, and Mariners are my dark horses to win their divisions i may sprinkle something on just for fun.
