The Rockies probably would be willing to give him up, but he also has a no trade clause. Which means he is only going to go to a team that has a realistic chance of making the playoffs, which would not really be Baltimore. At most, they have an outside chance. The only team that really meets that and has a spot for him would be Minnesota, who cannot afford that salary. If he is going to play for a team that is not going to win, he might as well just stay in Denver, where he is loved by the fans, has a great park to hit in, where his home and family is.
