Wait, how long is this gonna go on for?

So now that Flash is pretty much on the way out, and Brett Myers is on the way in, the Phillies are presented with a new confounding question.

Why can't Mr. Myers pitch more than just the 9th inning? Are there established rules for how many outs your closer can get? Mariano Rivera used to get the ball in the 8th from time to time. Sure Brett Myers is no Rivera, but he's been a starter for his whole career....we all know he can pitch more than one inning. Sure, if your pitcher is going to come up in the 8th, you can't do this. But there have been multiple instances where this was not the case, yet there was no Myers in the 8th.

How many games will our middle relievers have to blow before this happens?
