Continuing with minor-league offensive leaderboards.

The first batch was limited to players on what I call "MLB Track":

• Rookie ball/short season by age 19
• Low-A by age 20
• High-A by age 21
• AA by age 22
• AAA by age 23

This group has all of the hitters, regardless of age-relative-to-level.  But those more than two years older than "MLB Track" level are indicated with a "(+3)" or the like.

Prospects on the "MLB Track" are in red or (if they had a limited number of appearances) in bolded green.

Other prospects are in black or (if they had a limited number of appearances) in regular green.

Hitters with between 100 and 150 PAs are in green.  Those with fewer than 100 PAs do not appear at all (nor do prospects in foreign leagues).

Traded players are placed in the right spot, but without rankings, and in blue.

My "Spectometer" benchmarks indicating a high level of performance in each catetory are marked off by "==="

Is that enough explanations?

Note: Some guys make this list with enormous walk totals, so it's not a hugely helpful leaderboard.  But it has a good track record as a warning sign when guys don't make it to 19% -- as in Stefen Romero and Tank O'Neill and Gabriel Guerrero.  (Neither Deej nor Kiv made the top 15, but no red flags ... both easily cleared 19%.)

Note: I wish Jackson were higher, but he was just a teenager getting his feet wet and there's not a lot of data yet.  There's lots of depth up top, and some or all of it may work out for the big club, but not even Deej and Kiv look like can't-miss guys.
