An Ohio Cup series would be fun. You figure the Guardians, with their big late season success, could continue that momentum into the post. But that is unlikely. And the Reds are similar to the 2006 Cardinals. Thus there is a chance, but again probably not happening.
Those ‘06 Cardinals got healthy at the right time, had two Hall of Famers, a third almost Famer, an Hall of Famer manager (which the Reds also have), and a legitimate number one ace who excelled under pressure. Even though they were not a good team, they had good players that missed a lot of time during the season and all were available come post season.
