I don't see who else it could be.  I know Iggy is nursing an injury currently but he is the only guy that makes sense that you want starting for a month.  Aviles goes to second obviously.

As much as I have been an advocate for Aviles over Iggy at this point in his development and as much as it really would hurt to lose Pedroia for that long I would be excited to see what Iggy showed us starting every day for awhile.
