From MLBTR:
"Starter Garrett Richards could be available in a deal for a top starter such as Zack Greinke, Cole Hamels or Francisco Liriano."
I would like a Liriano-Richards Swap. Richards was the 89th highest rated prospect going into 2012. He is having a decent season between AAA and the Majors, but he is a guy that can help the big club in the near future if not immediately. A righty that has a career 3.47 minor league ERA and has some of the best stuff in the Angels farm system.
Here is a quick scouting report from halosheaven going into this season:
"He has two great pitches: a booming, mid-to-high 90's fastball that he can cut in against lefthanders, and a dynamite slider with hard downward bite. Every once in awhile he throws a sweet change-up, so with more consistent execution his arsenal could total three plus offerings. Bringing back his get-me over curveball down the road would be icing on the cake."
