The Reds go to St. Louis with an eight-game lead. They've surprised even themselves.
"I don't think anyone imagined the gap would be what it is," third baseman Scott Rolen said. "When (the Cardinals) were here, they outplayed us in every aspect of the game. Everyone kind of felt it was going to go the other way because of the momentum. I'm not a believer in momentum in baseball."
Rolen was referring to series in August in which the Cardinals swept the Reds.
The Reds are 13-4 since. The Cardinals have only won one of the six series they've played since leaving Cincinnati and have gone 5-12 overall.
The two clubs meet for the final time in regular season in a three-game series that starts Friday night in St.
