Have you made the trade yet? What are you waiting for? Make it! Russel Martin will not maintain his level of production. Neither will Lohse. Cruz is legit, but you are getting the best player in the deal in Lester, you are improving your 3B position, and the catchers are kind of a wash. You are losing Cruz, but your outfield will still be good. And most importantly, you are selling high on several players (Lohse and Martin) that are not likely to maintain their production which is exact;y what you should be doing in fantasy baseball. That is a great trade for you.
