i would not get rid of elvin, lagares, or tovar
honestly lagares has the best shot of anybody above AA of being an everyday mlb player (only if he can stay in center) due to his high contact ability
tovar is already a better major league player at back up SS than quintanilla (or even possibly hicks)
elvin ramirez is a very useful young bp arm that gets bashed for having little control in his mlb debut even though it was clear that (at only 24) he was not quite ready....hes not a huge loss but there is a reason that scouts like this kid - he has a very big arm
personally i am ok w/ dfaing havens and german to start and im not totally opposed to getting hefner or lutz off the roster (or dfa hicks and give tovar the job)
