Just went and read the actual article. You'd have to assume 2011 would be the earliest reasonable projection for Vitters to reach the majors, with him possibly reaching AA this year, but more than likely topping out in high A (Peoria is actually low A ball).
Don't get too excited about mashing low A ball yet. If he can keep mashing up to Tennessee, however.....
You always wanna take it slow with a 19 year old.
On a side note, bleacherreport needs to get some Sox writers that don't blow. Replace Alexei Ramirez with Gordon Beckham right now? Jesus.
