Here's an approach that I use pretty often:
I know there's a guy on the wire that I want. So far no one's made a move, so I think I can risk waiting a day or two. What do I do? Pull an old two for one trade! Maybe package Kearns and a pitcher, touting Kearns' huge potential, for an upgraded outfielder. Or even do Klesko and a pitcher for a possible stud outfielder. Once the trade is done, you grab your man!
I'd say Hinske is your weakest link in the infield, so maybe you could combine him and a pitcher in a trade as well.
No sense waiving someone that you feel should be on someone's roster.
Pull this off, and you've upgraded two positions instead of one!
