Another thought, I don’t know much about TZ — I haven’t browsed your article yet - but for minor league data, since it’s compared to league average, would it be easier to post higher scores in the lower levels assuming that the talent is lower in A ball than it is in AA-ball? I wonder how it translates across levels?
I ask because Mike McBryde — who has a reputation as a very good defensive OF — but up a +20 by R/150 in his season in SK, but since then, he’s played closer to average in CF. Is it talent level thing?
This is really cool, I’ll have to think about it for a bit.
Now with better readability

Keep in mind
That TotalZone suffers from the same syndrome all defensive metrics do- TINSTAAPDM (There Is No Such Thing As A Perfect Defensive Metric). Try to think of it more like an estimate.
It’ll be very interesting to see how it translates across levels, like you mentioned. It’d probably take a while to compile all that data.

Antoan Richardson is getting some really nice scores for his defense in CF.
nice
But where is the fake bunt category?

I live on Minor League Splits anyway and this just makes it better.

Here you go, for 2008
Villalona: +3 R/150 (1B, 180 chances)
Noonan: -4 R/150 (2B, 382 chances)
EME: +2 R/15 (LF, 259 chances)
Culberson: -9 R/150 (SS, 286 chances)
Williams: N/A for catchers (16 errors and 19 PB last season, though I’m sure what those are telling you given the quality of command in the low minors)

I Can't Seem To Get This To Work - What Does It Say About Sandoval's Career Minor League Defense At 1B And 3B?

Thank you. So how is this to be interpreted? Villalon +3 is this good or bad because believe he had 14 errors. Noonan -4 thought he was good. EME +2 is this decent?
Actually, Total Zone is rather bad for rating 1B's
The system only measures plays made on batted balls, not on receiving throws. If the 15 errors are any indication, Villalona’s a pretty horrendous receiver, and Total Zone is seriously overrating his defense.

Additionally
Here’s the article explaining Total Zone
If I’m reading it right, it rates infielder based on their efficiency at turning ground balls into outs. Since it doesn’t account for receiving at 1B, I think it may end up assigning all the “blame” for Villalona’s 15 errors (and Neal’s 8 errors, in only 38 games) to the infielders making the throw (it doesn’t give them demerits for the error, but simply records it as a failed fielding opportunity). That could mean the system is slightly underrating Culberson and Noonan, who had to put up with some pretty stinky work from Villalona and Neal at the cold corner. Still, Culberson had 35 errors himself in only 79 games, so it’s quite possible that he’s actually the one making Villalona and Neal look bad. I don’t see any way to separate out which party is guilty, beyond the (often unsatisfactory) judgment of the official scorer.

+3 is slightly above average and -4 is slightly below averages, but this stat isn’t that accurate (lack of PBP data in the minors), and the sample size is pretty small too. So don’t pay too much attention to the details – basically Villalona, Noonan, and EME appear to be around average, and Culberson looks below average.
..so allow me to present Tim Lincecum and Matt Cain as two sweet, sweet bottles of warming hooch.
Here's another interesting one
Frandsen’s last minor league season as a (near) full time 2B in 2006: -12 R/150
