The Phillies are doing extensive homework on the Dodgers' minor-league system in prep for trade talks regarding ace Cole Hamels, according to USA Today MLB columnist Bob Nightengale.

Hamels has been a name mentioned in trade rumors this offseason. It's been reported the Phillies are looking for a few elite prospects in return for Hamels, who went 9-9 with a 2.46 ERA in 30 starts last season.
