The start is being made possible by moving his next start up to Friday (it was scheduled for Saturday). My preferred solution was to start Bonser on Saturday and limit him to 60 pitches or so, but this is better because he'll be starting the playoff game on regular rest.
That means the question spots in the rotation are in the 3 and 4 spots, and Brad Radke could go a long way towards answering one of the questions with his start on Thursday. I'll go on record as saying that I don't think that Radke will be on the playoff roster, because honestly that would be ridiculous, based on the damage he has suffered in his shoulder. I certainly hope I'm wrong; Radke at 70% is better than any of the other options available for Game 3. I just suspect that his body is going to let him down.
So, that would leave Game 4 for either Silva or Garza. As I said yesterday, watch carefully; the way they pitch this week very well could be the determinative factor on who gets to start (and who is likely left off the roster altogether).
