It already happened last season. Aside from baltimore we only played the white sox, the angels and the mariners and got extra games against the diamondbacks and pirates. It rotates every season.

I hate the Phillies but they've earned a few "breaks" here and there. Someday, we'll all say, "Man, the Nats got a break on that." We ain't quite there yet.
