Is this a good trade?

nope i would strongly advise you to leave this alone......adrian gonzalez is the best 1st basemen in the league so you dont want to be dealing him he and ortiz also play on one of the most potent offensive teams in the league as well so you dont want to be dealing either.......i would however try to deal chacin though....any dude that plays his home ball in coors field is a guy you dont want pitching for you.....i wouldnt necissarily trade him for shields but i would try to find someone that fancies him and sell him off cuz he is a liability.......all the best the rest of the season
