Seriously. If the city of Cincinnati can only draw 12,000 to a game in September with a team on the verge of it's first playoff appearance in 15 years, why not play about 9 home games in Slugger Field next season? It holds 14,000, and I'm sure with temporary seating, it could get up to 20,000 or so and lets a large Reds fanbase see the games.
Personally, I've always thought it was a good idea for years for MLB to let teams hold some series in a minor league affiliate's stadium if they wanted. Maybe not financially smart if you're the Yankees or something, but for someone like the Reds it would be pretty cool.
