Minor League Batted Ball Charts
More great Edison-work being done here:

(Hat tip: studes)
One thing I would do is…
... I can’t stand batting average. I hate it the more I see it. The same applies to those “Inside Edge” charts you see with the batting average in each zone. We know the relative values of the double, triples, (and when applicable to the chart) HR to the single. Why treat all of them as “1”. FirstInning.com at least shows you the numbers of XBH, but, I think it’s clearer to combine the two.
If you are going to use PA or AB or ball in zone, etc as your denominator, then the relative weights per single is: 1.4 for doubles, 1.8 for triples, 2.2 for HR. All you have to do to put something on its equivalent batting average scale is this:
1- figure out how many “weighted” singles you have per opp… let’s say the league average is .290
2 - figure out the basic batting average… let’s say the league average is .270
3 - reduce your weighted singles per opp by 27/29
It was also unclear to me whether HR were included in the batted ball chart on FirstInning.com. In some cases, it should be, and in some cases, it shouldn’t. It all depends on what you are using the charts for.
