Because the Reds are very good at beating up on crappy teams like the Cubs, D-Backs, Pirates, etc...but they tend to struggle against decent teams. Ironically, a lot like the Dodgers were the last couple of years. That, and the Reds have lost nine straight in LA IIRC?
I've had a very, very good week...but this series is a difficult one for me to get a handle on. No play for me.
