Chris Carpenter is leading the league in ERA and could win another Cy Young award, but he doesn't feel as though his stuff is as good as 2005. ?I?m having a good year, but I?d have a ways to go before I matched ?05," said Carpenter. "I could be pitching better than I am. I think just to be out there again and having success is gratifying, but I want to be better than that. I want to go out there every time and feel like I?ve pitched my best, and I haven?t always felt that way. But from where I came from, sure, I think I?m doing OK.??
