The Rockies got the difference between Harang's and Hernandez's salary. By DFA Harang, if someone picks him up, the Rockies essentially sold Hernadez for 4.75 million. If multiple teams put in a claim then the Rockies come out with a prospect. If only one team is slightly interested then they netted themselves money. It really shouldn't take above a c--prospect to get him. The better the prospect offered, then the more of that 4.75 million should come your way.
