Not to nitpick, but Baseball Reference has him at 23 in Fort Myers and Beloit (2010) and then 24 in Fort Myers and New Britain (2011). He's a May birthday andturned 23 in 2010 and 24 in 2011, but since he didn't move straight to AA in 2011, he was more likely 24, or was only 23 for days at most, so most of his time in AA was as a 24 year old. While he might only be "older than average," if we compare his age to Florimon and Escobar, our other two uninspiring middle infielders, competing for the same spots,both were younger in AA. Meanwhile, Aaron Hicks did his mashing at AA at 22. Parmelee was 22. Joe Benson, 22. So, while Dozier may have been "only above average" the players I listed aren't expected to be much more than ML regulars/starters (except maybe Hicks) and all these guys were in AA before Dozier and hitting as well or better. My point, ultimately, is that his AA numbers at age 24 were used to evaluate him, so it's not a surprise that those numbers wouldn't be representative of what he could do in the majors and why most people thought he was rushed, or at least should have been better evaluated in AAA.
