The San Diego Padres- I don't consider them to be an underdog, unless they have to sell off everyone.
The San Fransisco Giants- Giants have strong pitching, if they can pull together a lineup they will be in there.
The Washington Nationals - Hahaha
The Seattle Mariners -
The Baltimore Orioles - No chance
The Kansas City Royals- They are starting to put together a nice team(there more like TB then any other choices)
The Pittsburgh Pirates- Hahaha no chance
The Cincinatti Reds - Good young talent, tough division
The Oakland Athletics - Oakland always seems to hang around
Other (Tigers, Braves, et cetera. I only have ten options) Tigers are not an underdog, more like under achievers, Braves are ok, but they have to go threw Philly and NY, plus its about that time for Florida's every 6th year title run.
