The Rockies have spent this winter talking up second base prospect Jayson Nix. But that doesn?t mean they are afraid to throw competition for the starting job into the mix. The Rockies have agreed in principle on a one-year deal with veteran Marcus Giles, with a few remaining wrinkles to be ironed out. ?We are getting pretty close. We are going to get it done, but it?s not done yet,?? agent Joe Bick said today. It?s likely to be a non-guaranteed contract though Bick stressed that it?s premature to say that because it?s not finished.
