There are going to be a lot of bad days in a rebuilding project, and Tuesday may have been one of the worst of them.

If you're an Astros fan you hope, not even necessarily that Jonathan Singleton and Jarred Cosart combine to be better than Hunter Pence, but even that they just make their contributions when the Astros get good again rather than wasting them on a lesser roster like Pence may have.

But in the interim, there is a reality about trading a player like Pence, who hit the walkoff home run Tuesday that sent the Astros to their fourth straight loss, 4-3 to the Phillies.
