The Rockies have an excellent core with Troy Tulowitzki, Carlos Gonzalez and Ubaldo Jimenez, but more help is needed. Manager Jim Tracy said Thursday that adding an "impact bat" is a top offseason priority. The Rockies will target catcher/first baseman Victor Martinez, if he becomes a free agent, but he could be out of their price range. "My first reaction is that I would just like someone in here to step up and be that bat," Tulowitzki said. "The way this organization is run, in-house would be the first choice. We need somebody to step up and really be that threat. If that doesn't happen, then we will be forced to go out and get someone."
