I guess it is possible, but still very unlikely. He has only played 39 games at AA. maybe he will make it to AAA by the end of next year, but to think he will make that huge of a leap is so unlikely.
The 40 man roster for next year will be vastly different (no Schill, timlin, van every, aardsma, casey, colon, byrd, etc...) so you will likely get other infielders. Plus, Velasquez is on the 40 man now and while he may not be next year, he plays infield and was the call up this year.
