This upcoming 2013 season will be a great one. There are ten legitimate titles contenders, five in each league. On paper, these are the teams that have a great shot at winning a title. This free agent period has been a memorable one with Zack Greinke signing with the Dodgers and a true shocker; Josh Hamilton signing with the Angels. There will be new faces in new places this year. Barring any injuries, these ten teams are true contenders.
