It’s very simple. The Sox needed to sacrifice some offense to get some pitching. Pedro is on the DL. Lowe is struggling and is back in Boston for more surgery on his nose. The overall sox pitching staff has been erratic at best. The future of the sox infield is Hanley Ramirez, Sanchez, Youkilis, and Shoppach. They were able to keep all of these prospects and still land one of the top relievers in the NL from the last couple years. Kim is 24 and had 36 saves, 8 wins, and a 2.04 ERA last year. He instantly adds flexibility to the sox pitching staff. I hate to see Hillenbrand go, but he was the best piece to give up at this point. Hoss has spoken.
