The Astros dealt anyone and everyone that contenders had interest in at the deadline (outside of Jose Altuve), and they are laying the groundwork for contention in a few seasons.
A complete lack of starting pitching has left the Rockies among the worst teams in baseball. They have some young arms and a solid offense, so they could return to contention sooner rather than later.
The Cubs are in full-on rebuilding mode, and the recent call-ups of Brett Jackson and Josh Vitters gives Cubs fans something to get excited about down the stretch and moving forward.
San Diego Padres
Opting to re-sign Carlos Quentin and Huston Street while holding on to Chase Headley, the Padres are looking to return to contention sooner rather than later. They'll be a team to watch next season if they can add a starter or two, either from within or on the market.
The Phillies have had an abysmal year, dealing with injuries to a number of their superstar players and falling out of things early. That led to Hunter Pence, Shane Victorino and Joe Blanton being moved, and it will be interesting to see where the franchise goes from here.
The Marlins spent big in the offseason, hoping to usher in their new stadium with a contender, but a rough stretch led to them selling off the likes of Hanley Ramirez, Anibal Sanchez and Omar Infante at the deadline. They have been one of the biggest disappointments of the year.
A horrible week leading up to the trade deadline was enough for the Brewers to sell, and they dealt ace Zack Greinke to the Angels for a trio of top prospects. The team has built its farm system back up and still has a solid offense. If the Brewers can shore up their bullpen and add a starter, they should be right back in the thick of things next year.
