What should i so with Chris Young?? SD?

Keep him. He'll probably come off the the DL soon enough. I don't think you can trade a player who's on the DL. Besides, he hasn't been pitching up to his potential. Cordero is useless. If I were you, I'd drop Cordero. If you're in a 10-team league, I'm sure there are a few other closers on the free agent list who're just as capable of getting saves as Cordero.
