Here's an article from the Rockies official site:http://colorado.rockies.mlb.com/news/article.jsp?ymd=20070722&content_id=2102203&vkey=news_col&fext=.jsp&c_id=col
It's kind of odd how tight lipped everyone in the organization is being about it.
As for Fuentes and the closer's role, I still think it's his job but he should have to prove it with some solid outings before retaining the job. Corpas has done very well in the role so far so it will be hard to move him from that role.
As for teams being interested in Corpas, that's great for them, but in reality, the Rockies would be crazy to trade him. In all liklihood, he will be the Rockies closer next season, as I think Fuentes will either be traded or become too expensive for the Rockies to keep.
