Evaluating Minor Leaguers

After my post earlier this morning about Luis Montanez and his age disqualifying him from prospect status despite his excellent statistics, Baseball Prospectus posted a discussion of their own about evaluating minor leaguers based on their stats. A quick comparison of Luis Montanez and Matt Wieters (go here and search for "Montanez" to see Wieters, Reimold and Montanez side-by-side):

Montanez has peak translated EQA of .248.
Wieters has a peak translated EQA of .360, the highest number in the minors.

Read those numbers like a batting average (and just ignore for a minute that Wieters has compiled his in only 107 at-bats) and you'll see why I man-crush on Matt Wieters and have ignored Luis Montanez until today. For comparison's sake, only one Major Leaguer has a 2008 EQA above .360: Albert Pujols and his .370 number. Even the league-leading .309 Wieters compiled in Frederick is impressive; it's much lower because the Carolina League is farther from the Majors than the Eastern League, and Wieters was the same age in both leagues.
