This one is huge. Adrian Gonzalez has been targeted by Boston for several years now and it finally looks like he is headed over. This effectively ends the pursuit of Adrian Beltre as Gonzalez will shift Kevin Youkilis over to third base, his original position.
The cost is significant. Boston is sending first round draft picks Casey Kelly and Rey Fuentes, along with first base prospect Anthony Rizzo and a player to be named to San Diego. But to pick up a player of Gonzalez's caliber, you have to give up quite a bit. Boston also has five early draft picks next year to help absorb some of that loss to the organization as Beltre, Victor Martinez, and Felipe Lopez will all bring compensatory draft picks.
Gonzalez will be 29 next May, so he is still young. He is also a big-time power threat as he has hit 30 or more home runs each of the last four years while playing in San Diego, a notorious pitcher's park. This is a good pickup for Boston.
