#1. Texas Rangers
The Phillies and Rangers have historically been excellent trade partners, as seen with the Hamels and Michael Young deals.
Most likely, Hellickson would be sent in a package, which could include Carlos Ruiz. The Phillies have been scouting the Rangers major league system, which could mean a trade larger than one made with Boston or Miami.
Texas also has one of the best records in baseball. As I mentioned with Boston though, you can never have enough pitching during a post-season run. Veteran Kyle Lohse is struggling for them at the bottom of the rotation, creating a perfect spot for Hellickson to fill in. Add the injury history with Yu Darvish, and Texas would love to add starting depth.
