"I don't feel like it's over at all," he said. "Are you kidding me? I still look at our lineup, we're capable of scoring runs. I know we haven't done it with Matt, but I know we're capable. I understand where we are, but to say it's over is just crazy."
Mattingly said he's buoyed by the comeback of last year's St. Louis Cardinals, who were 10 1/2 games out of first place on Aug. 5, made the playoffs as a Wild Card and won the World Series.
"After seeing that pennant race, we've got to win today and have a chance to win the series tomorrow," said Mattingly. "Then go to Arizona and win that series and go home and beat St. Louis. For me, I don't think it's over at all. We've got to keep this in perspective.
"I remember, and I think a lot about it, we swept St. Louis four straight and they were getting booed and it looked like a dead team with no chance. Two weeks later they caught fire and rolled right through. We've got to get on that roll. We've shown no indication of that, but when will it start? Today?"
