I don't think you need to look so deeply. Haren isn't cheap anymore after 2010. He jumps to $12.75 Million in 2011 and the same in 2012. He has a $15.5 Million option in 2013 with a $3.5 Million buy-out. Assuming the buy-out and spreading it over 2011 and 2012, he's roughly a $15 Million per year guy the next two years. With an ERA in the high 4's and scads of homers, the D-Backs are lucky that they didn't have to add players to get some one to take him. On paper, Haren looks a lot like Aaron Harang last year at this time (or two years ago). Haren and Harang even sound alike. I think the D-backs did pretty well to get Saunders, who will hold a spot in the rotation and provide similar production to what Haren provided in 2010 at an over $10 Million savings (and a prospect like Skaggs to boot) while exiting the deal when the bargain came to an end.
