Rockies starter Aaron Cook was pain free after throwing 50 pitches on Saturday. However, there is still no guarantee that Cook will start on Thursday against the Padres. Colorado manager Jim Tracy told the Denver Post that he won't make a final decision until next week. "I felt g-o-o-d," Cook kidded. "Seriously, I felt really good. I would like to start, but I'm going to do whatever the club needs."
