Aaron Cook is still holding out hope that he'll be able to return to the mound for the Rockies this season. The right-hander threw a 25-pitch side session on Sunday, but the team still isn't expecting him to return until the 2010 season. "That's my goal," Cook, who has been out since Aug. 22 with a strained right shoulder, said of pitching in 2009. "I understand they are trying to be cautious, but I believe I will be in a big-league game based on how I feel right now."
