As Im sure many of you have noticed, I linked Kensai's A+ ball prospect updates. I posted a similar story on minorleagueball.com and someone asked me about the progression of Aaron Miller. They wanted to know about his changeup progression, if there was any. Does anyone know anything I can pass on to the poster on minorleagueball?

Also, does anyone have any idea about his possible advancement from A ball to AA?

Thanks in advance
